uses of computer in medical field wikipedia

[60] Kalbkhani et al. Saritha also suggested to use spider-web plots. For example, staff records, recording incoming and outgoing time of … A low specificity reduces the acceptance of the CAD system because the user has to identify all of these wrong hits. In contrast, many economists and artificial intelligence experts believe that fields such as radiology will be massively disrupted, with unemployment or downward pressure on the wages of radiologists; hospitals will need fewer radiologists overall, and many of the radiologists who still exist will require substantial retraining. In CAST systems the FP rate must be extremely low (less than 1 per examination) to allow a meaningful study triage. Uses of computers in Medical Field: Hospital Management System should maintain by the computer to know the complete environment and working operations of hospitals and etc. [53], In 2010, Wang and Wu presented a forward neural network (FNN) based method to classify a given MR brain image as normal or abnormal. There is no doubt that ICT is one of the latest mastered human brain does not stop this development at a certain point or area of life without the other has had this technology a significant impact and contribution of the actors in the health field, particularly in the provision of medical service and high level .. The two principal characteristics of a computer are: It responds to a specific instruction set in a well-defined manner and it can execute a prerecorded list of instructions call a program. Manual analysis of these images can be time-consuming and unreliable. [76], Green channel filtering is another technique that is useful in differentiating lesions rather than vessels. You will receive a link to create a new password. CADs can be used to identify subjects with Alzheimer's and mild cognitive impairment from normal elder controls. [76] The main objective of this method is to provide contrast enhancement, especially darker regions compared to background. [76] Some beneficial properties of SVM include[83], Multi-scale approach is a multiple resolution approach in vessel segmentation. These methods are SVM, multi-scale, vessel-tracking, region growing approach, and model-based approaches. Use of Computers within the Medical Field: A laptop has become an important trade goods in each hospital. CAD detects the polyps by identifying their characteristic "bump-like" shape. Especially in diagnostic and surgical fields. Medical Offices. [29] At this a volumetric dataset with up to 3,000 single images is prepared and analyzed. The field of digital image processing refers to processing digital images by means of a digital computer. To this end, various noninvasive and low-cost markers have been proposed, using ultrasound-image-based features. [81] This technique is the least used pre-processing method in the review from 2014. f Uses of computers in Medical Field Hospital Management System Specialized hospital management softwares are used to automate the day to day procedures and operations at hospitals. 6.) Basic three sub-steps on medical imaging are segmentation, feature extraction / selection and classification. Nowadays, patients should have proper appointment to contact with … have first reported a trained Fully Convolutional Network (FCN) for detection and quantification of neurofibrillary tangles (NFT) in Alzheimer's disease and an array of other tauopathies. [76] In addition, green channel filtering can be used to detect center of optic disc in conjunction with double-windowing system.[79]. Their uses include storing patient related data, housing knowledge bases, providing the logic and circuitry for medical equipment, scanning and imaging the body, and facilitating speedy communications.Patient records are stored on computer databases in the medical field. In the following years several commercial CAD systems for analyzing mammography, breast MRI, medical imagining of lung, colon, and heart also received FDA approvals. [57] Genetic pattern search method was applied to identify abnormal brain from normal controls. are the basic operations of a computer, Uses Therefore, one advantage of using this technique is the increased analytical speed. Reliable early-detection and risk-stratification of carotid atherosclerosis is of outmost importance for predicting strokes in asymptomatic patients. Custom Medical Device Manufacturing. But we know, it's not just the education sector which computers have impacted. The latter's advantage is that only the markings which are approved by the radiologist are saved. There are various uses of computer in medical field as it plays a vital role in every medical office. The FCN reached near-practical efficiency with average processing time of 45 min per WSI per Graphic Processing Unit (GPU), enabling reliable and reproducible large-scale detection of NFTs. It contributes a lot to the hospital administration where all the administrative processes are computerized. [76], Histogram equalization is useful in enhancing contrast within an image. Biomedical Signal Processing and Control, 2006. Round lesions (lung cancer, metastases and benign changes) from 1 mm are detectable. There is a wide variety of use and need for a computer in the medical field. The normalization of input data includes noise reduction, and filtering. Depending on the CAD system these markings can be permanently or temporary saved. Computer-aided detection (CADe), also called computer-aided diagnosis (CADx), are systems that assist doctors in the interpretation of medical images.Imaging techniques in X-ray, MRI, and ultrasound diagnostics yield a great deal of information that the radiologist or other medical professional has to analyze and evaluate comprehensively in a short time. Procedures to evaluate mammography based on magnetic resonance imaging exist too. The operations done by the medical experts are completely recorded by the computers for future references and also to avoid complications. {\displaystyle f'=f+\mu -\lambda }. But, without computers, the healthcare system wouldn’t run as smoothly. These elements are referred … Effective designing, implementing and analyzing for EHR is a major necessity on any CAD systems. Computers used in database storage, networking, information collection and patients scanning. [79] Similar approaches that utilize the concept of centerline are the skeleton-based and differential geometry-based. Morphological operations is the second least used pre-processing method in 2014 review. Various types of techniques help create images of the human body, or body parts, for medical … Computers serve myriad purposes in the field of medicine, often playing a predominant role in medical offices throughout the world. There is vital use of computers in medical assisting field. Every detected region is analyzed individually for special characteristics: 4. It uses a 4.77-MHz Intel 8088 chip and has 64 kilobytes RAM, one 5.25-inch floppy diskette drive and PC … They are really important. CT lung examinations) the FP-rate could be 25 or more. Patnaik, and N.R. Round lesions that vary from 5–10 mm are easily overlooked. CAD is available for detection of colorectal polyps in the colon in CT colonography. Data Storage 2. It contributes a lot to the hospital administration where all the administrative processes are computerized. Thus, by the late 1980s and early 1990s the focus sifted in the use of data mining approaches for the purpose of using more advanced and flexible CAD systems. heart, lung, ribcage, blood vessels, possible round lesions, Average greylevel value analyze within a ROI, Proportion of greylevels to border of the structure inside the ROI, Flexibility – Highly flexible in terms of function, Simplicity – Simple, especially with large datasets (only support vectors are needed to create separation between data), This page was last edited on 2 February 2021, at 17:14. Maitra, M. and A. Chatterjee, A Slantlet transform based intelligent system for magnetic resonance brain image classification. We can use computers for the administration of a hospital. This method is important because it provides the maximal contrast between diabetic retinopathy-related lesions. Intensity variations in areas between periphery and central macular region of the eye have been reported to cause inaccuracy of vessel segmentation. The changes is that majority of the medical students are computer literate these days. In 2014, Padma et al. CAD is an interdisciplinary technology combining elements of artificial intelligence and computer vision with radiological and pathology image processing. Moreover, while many positive developments of CAD systems have been proven, studies for validating their algorithms for clinical practice has hardly been confirmed. The technology and the instruments have helped save lives of millions of people. Computer-aided detection (CADe), also called computer-aided diagnosis (CADx), are systems that assist doctors in the interpretation of medical images. [68] Other approaches with decent results involve the use of texture analysis,[69] morphological features,[70] or high-order statistical features[71], CADx is available for nuclear medicine images. λ Since the early 1970s, some of the very early CAD systems in medicine, which were often referred as “expert systems” in medicine, were developed and used mainly for educational purposes. Modern computers can do billions of calculations in a second. Surgical Procedures 3. [67] Polynomial kernel SVM has been shown to achieve good accuracy. The absolute detection rate of the radiologist is an alternative metric to sensitivity and specificity. These sub-steps require advanced techniques to analyze input data with less computational time. suggested to apply naive Bayes classifier to detect pathological brains.[63]. The MYCIN expert system,[9] the Internist-I expert system[10] and the CADUCEUS (expert system) [11] are some of such examples. [24], During the preprocessing stage, input data requires to be normalized. It can be put under four main categories that include: 1. Medical Imaging. [27], Recent advances in machine learning, deep-learning and artificial intelligence technology have enabled the development of CAD systems that are clinically proven to assist radiologists in addressing the challenges of reading mammographic images by improving cancer detection rates and reducing false positives and unnecessary patient recalls, while significantly decreasing reading times.[28]. proposed to use Ripplet transform. The polynomial KSVM performs better than linear SVM and RBF kernel SVM. [74] This technique is also being used in optic disc identification.[79]. One disadvantage of this technique is that it requires manual selection of seed point, which introduces bias and inconsistency in the algorithm. [64], In 2019, Signaevsky et al. Automation of medical diagnosis labor (for example, quantifying red blood cells) has some historical precedent. Computer science is used on a daily basis, not only to keep … [86][87] An op-ed in JAMA argues that pathologists and radiologists should merge into a single "information specialist" role, and state that "To avoid being replaced by computers, radiologists must allow themselves to be displaced by computers." Today's CAD systems cannot detect 100% of pathological changes. [65], Eigenbrain is a novel brain feature that can help to detect AD, based on Principal Component Analysis[66] or Independent Component Analysis decomposition. However, after the breakthrough paper, “Reducibility among Combinatorial Problems” by Richard M. Karp,[12] it became clear that there were limitations but also potential opportunities when one develops algorithms to solve groups of important computational problems.[8]. After pre-processing of funduscopic image, the image will be further analyzed using different computational methods. used combined wavelet statistical texture features to segment and classify AD benign and malignant tumor slices. New information on medical topics is readily accessible via the Internet and handheld computers such as palmtops, personal digital assistants (PDA). proved removing spider-web plots did not influence the performance. Their feature vector of each image is created by considering the magnitudes of Slantlet transform outputs corresponding to six spatial positions chosen according to a specific logic. [58] Das et al. [74], Region growing approach is a method of detecting neighboring pixels with similarities. X-ray or other types of images are scanned for suspicious structures. Non-uniform illumination correction is a technique that adjusts for non-uniform illumination in fundoscopic image. [55], In 2013, Saritha et al. [62], In 2015, Zhou et al. [24] This fact may cause the difficulty for obtaining FDA approval for commercial use. Everything from patient scheduling to billing to filing insurance claims takes place through a computer. Although CAD has been used in clinical environments for over 40 years, CAD usually does not substitute the doctor or other professional, but rather plays a supporting role. [81] Walter-Klein transformation is then applied to achieve the uniform illumination. CAD is used in the diagnosis of breast cancer, lung cancer, colon cancer, prostate cancer, bone metastases, coronary artery disease, congenital heart defect, pathological brain detection, Alzheimer's disease, and diabetic retinopathy. [80] Microaneurysms and hemorrhages are red lesions that appear dark after application of green channel filtering. Processing may contain a few sub-steps depending on applications. The surface representation is a surface normal to the curvature of the vessels, allowing the detection of abnormalities on vessel surface. Hospital organization: The hospital is an essential association. For instance, some hospitals use CAD to support preventive medical check-ups in mammography (diagnosis of breast cancer), the detection of polyps in the colon, and lung cancer. Imaging is used to recognize early signs of abnormal retinal blood vessels. For example, in mammography CAD highlights microcalcification clusters and hyperdense structures in the soft tissue. Two elements are needed for this technique to work: similarity and spatial proximity. Each study result depends on its basic conditions and has to be evaluated on those terms. [84] Lastly, template matching is the usage of a template, fitted by stochastic deformation process using Hidden Markov Mode 1. Of Computer in Business Organizations, Differentiate To avoid excessive false positives, CAD ignores the normal colon wall, including the haustral folds. Another application is CADq, which quantifies, e.g., the size of a tumor or the tumor's behavior in contrast medium uptake. Results over 160 images showed that the classification accuracy was 98.75%. Early detection of pathology can be the difference between life and death. Parametric uses geometric parameters such as tubular, cylinder, or ellipsoid representation of blood vessels. were the first to apply wavelet entropy (WE) to detect pathological brains. Answer (1 of 13): Computers play a key role in the medical field. The expectation of what computers can do was unrealistically optimistic among these scientists. [79] This technique is used to increase local contrast. f Geoffrey Hinton, the "Godfather of deep learning", argues that (in view of the likely advances expected in the next five or ten years) hospitals should immediately stop training radiologists, as their time-consuming and expensive training on visual diagnosis will soon be mostly obsolete, leading to a glut of traditional radiologists. CAD systems process digital images for typical appearances and to highlight conspicuous sections, such as possible diseases, in order to offer input to support a decision taken by the professional. CAD is fundamentally based on highly complex pattern recognition. Overall, results of clinical trials about sensitivity, specificity, and the absolute detection rate can vary markedly. Non-uniform illumination can be a potential error in automated detection of diabetic retinopathy because of changes in statistical characteristics of image. Increasing contrast between these two groups allow better visualization of lesions on images. [24], Some challenges are related to various algorithmic limitations in the procedures of a CAD system including input data collection, preprocessing, processing and system assessments. In 1998, the first commercial CAD system for mammography, the ImageChecker system, was approved by the US Food and Drug Administration (FDA). The following facts have a strong influence: Despite the many developments that CAD has achieved since the dawn of computers, there are still certain challenges that CAD systems face today. negative and positive). Digital image data are copied to a CAD server in a DICOM-format and are prepared and analyzed in several steps. suggested to use GARCH model. Normally a few thousand images are required to optimize the algorithm. [25] Today input data for CAD mostly come from electronic health records (EHR). These centerlines are maximal peak of vessel curvature. [73], Diabetic retinopathy is a disease of the retina that is diagnosed predominantly by fundoscopic images. During the beginning of the early developments, the researchers were aiming at building entirely automated CAD / expert systems. CAD is especially established in US and the Netherlands and is used in addition to human evaluation, usually by a radiologist. Doctors and administration staff uses computers to manage patient history and medicine stocks etc. False hits should not be saved, because an examination at a later date becomes more difficult then. The measured performance on test data of eight naive WSI across various tauopathies resulted in the recall, precision, and an F1 score of 0.92, 0.72, and 0.81, respectively. [61], In 2014, El-Dahshan et al. [74] Additionally, this approach can be used with 3D images. Computer uses in medicine . These first CAD systems used flow-charts, statistical pattern-matching, probability theory or knowledge bases to drive their decision making process.[8]. For example, staff records, recording incoming and outgoing time of … Classical snake contour in combination with blood vessel topological information can also be used as a model-based approach. The first CAD system for mammography was developed in a research project at the University of Chicago. After the structure is analyzed, every ROI is evaluated individually (scoring) for the probability of a TP. CADe can be done by auscultation with a digital stethoscope and specialized software, also known as Computer-aided auscultation. [8] The recognition of these limitations brought the investigators to develop new kinds of CAD systems by using advanced approaches. A seed point is required for such method to start. Besides vessel segmentation, other features related to diabetic retinopathy can be further separated by using this pre-processing technique. The computers can store huge amounts of medical data , You can use computers in many applications such as Medical images , Digital x-ray images , Digital microscope image , Electronic medical records , Clinical decision support systems , Hospital administration and Video games to hone laparoscopic surgeons , The computer technology has revolutionized the field of medicine . = Algorithms are generally designed to select a single likely diagnosis, thus providing suboptimal results for patients with multiple, concurrent disorders. the rate of false positives). Today it is commercially offered by iCAD and Hologic. Chaplot et al. However, the current literature agreed that some methods are used more often than others during vessel segmentation analyses. [76], Image normalization is minimizing the variation across the entire image. Results automatically save to an electronic database, ensuring that they are both accurate and readily available for other staff invol… The limited evidence available shows that silver coatings on endotracheal breathing tubes may reduce the incidence of ventilator-associated pneumonia. [24], There is also a lack of standardized assessment measures for CAD Systems. CAD systems are often utilized to help classify a tumor as malignant or benign. The Heart rate, pulse rate, brain readings and other specifications are monitored and recorded continuously through computers and finally the medical expert analyze the computer … different exposure parameter. Doctors use computers to manage and record patient information, which can help them to make a more accurate diagnosis, especially if multiple doctors are working with the same patient. [23] Computer-aided diagnosis (CADx) systems evaluate the conspicuous structures. [citation needed] However, while achieving high sensitivities, CAD systems tend to have very low specificity and the benefits of using CAD remain uncertain. [74][75] CAD has been employed to enhance the accuracy, sensitivity, and specificity of automated detection method. + Its classification accuracy was reported as 95.188%. So far its application has been limited to quantifying immunostaining but is also being investigated for the standard H&E stain.[1]. suggested to use pulse coupled neural network. 3. This allows the radiologist to draw conclusions about the condition of the pathology. A typical application is the detection of a tumor. The typical doctor's office relies heavily on computer technology for day-to-day operations. [2] However, the goal of some CAD systems is to detect earliest signs of abnormality in patients that human professionals cannot, as in diabetic retinopathy, architectural distortion in mammograms,[3][4] ground-glass nodules in thoracic CT,[5][6] and non-polypoid (“flat”) lesions in CT colonography. Their uses include storing patient related data, housing knowledge bases, providing the logic and circuitry for medical equipment, scanning and imaging the body, and facilitating speedy communications. Support vector machine is by far the most frequently used classifier in vessel segmentation, up to 90% of cases. [75], Image pre-processing, and feature extraction and classification are two main stages of these CAD algorithms. Computer-aided simple triage (CAST) is another type of CAD, which performs a fully automatic initial interpretation and triage of studies into some meaningful categories (e.g. Imaging techniques in X-ray, MRI, and ultrasound diagnostics yield a great deal of information that the radiologist or other medical professional has to analyze and evaluate comprehensively in a short time. [24], Due to the massive availability of data and the need to analyze such data, big data is also one of the biggest challenges that CAD systems face today. Model-based approaches employ representation to extract vessels from images. Commercial CADx systems for the diagnosis of bone metastases in whole-body bone scans and coronary artery disease in myocardial perfusion images exist. [56] Zhang et al. The FP-rate in lung overview examinations (CAD Chest) could be reduced to 2 per examination. [83] In order to successfully segregate blood vessel information from the rest of the eye image, SVM algorithm creates support vectors that separate the blood vessel pixel from the rest of the image through a supervised environment. [41][42] Polyps are small growths that arise from the inner lining of the colon. Medical computers are another area of technology that is becoming more commonplace in hospitals. Significance of computer technology in the health sector is actually unquestionable when it comes to medical imaging. Centers of vessels can be found using directional information that is provided by Gaussian filter. Nurses can also use technology to perform routine health checks such as EKGs, oxygen levels, and blood pressure. At the end of the processing, areas that were dark in the input image would be brightened, greatly enhancing the contrast among the features present in the area. On the other hand, brighter areas in the input image would remain bright or be reduced in brightness to equalize with the other areas in the image. [82] SVM is a supervised learning model that belongs to the broader category of pattern recognition technique. A neighboring pixel to the seed pixel with similar intensity is likely to be the same type and will be added to the growing region. To clear this perspective of Computer Applications in this field of Heath and Heath education we will discuss working system in RMI Hospital along with RMC medical college. Imaging. CAD systems seek to highlight suspicious structures. At low resolution, large-diameter vessels can first be extracted. Detecting blood vessel from new images can be done through similar manner using support vectors. Chaplot, S., L.M. Right from efficient data storage and easy access and sharing of information, to conducting medical tests and simulating complex surgical procedures, computers have an important role to play in the medical field. A 2008 systematic review on computer-aided detection in screening mammography concluded that CAD does not have a significant effect on cancer detection rate, but does undesirably increase recall rate (i.e. [74] Deformable methods uses objects that will be deformed to fit the contours of the objects on the image. However, the random detection of lung cancer in the early stage (stage 1) in the X-ray image is difficult. Combination with other pre-processing technique, such as green channel filtering, greatly improves the accuracy of detection of blood vessel abnormalities. Computerized Systems Used In Clinical Trials, "Computer-aided Diagnosis: The Tipping Point for Digital Pathology", "The Rebirth of CAD: How Is Modern AI Different from the CAD We Know? The less FPs indicated, the higher the specificity is. Radiodiagnosis, and other tests such as endoscopy, require computers. Many doctors no longer write prescriptions, but instead send a digital prescription from their office computer directly to the patient's pharmacy. [79], Vessel tracking is the ability of the algorithm to detect "centerline" of vessels. Ongoing studies in building innovative algorithms for all the aspects of CAD systems is essential. Three broad categories of model-based are known: deformable, parametric, and template matching. Leveling (harmonization) of image quality (increased contrast) for clearing the image's different basic conditions e.g. By increasing resolution, smaller branches from the large vessels can be easily recognized. Computer-aided auscultation is sensitive to external noise and bodily sounds and requires an almost silent environment to function accurately. Evaluation / classification Wound dressings containing silver sulfadiazine or silver nanomaterials may be used to treat external infections. found kernel support vector machine decision tree had 80% classification accuracy, with an average computation time of 0.022s for each image classification.
