Different ways to extract diagnostic data from thermal images, focusing on dynamic studies that provide valuable information on the physiological and pathological functions of the autonomous nervous system, are presented. Using fast-Fourier-transform analysis, the frequencies of the different regulatory processes and their relative contributions to the overall temperature oscillations can be determined and used to assess the physiology and pathophysiology of the sympathetic nervous system. Preliminary studies have shown that one can distinguish between local and central processes by the spatial distribution of regulatory frequencies over a region of interest, such as the human back, by mild local cooling or by the effect of sleep on local thermal regulation.<<ETX>>","PeriodicalId":439237,"journal":{"name":"[1991] Computer-Based Medical Systems@m_Proceedings of the Fourth Annual IEEE Symposium","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116983665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is shown that the seismocardiogram contains clearly defined points associated with the cardiac cycle that are correlated by analyzing simultaneous SCG and M-mode and Doppler echocardiograms. In the absence of heart disease, the resting seismocardiogram remains stable over a period of at least three months. There is a recognizable normal seismocardiogram that is altered by chronic left ventricular dysfunction, including myocardial infarction and dilated cardiomyopathy. Ventricular pacing produces reversible changes in the ventricular systolic wave component of the seismocardiogram. Thus, the normal seismocardiogram remains stable over time, but becomes altered during both chronic irreversible and acute reversible changes in left ventricular contraction.<<ETX>>","PeriodicalId":439237,"journal":{"name":"[1991] Computer-Based Medical Systems@m_Proceedings of the Fourth Annual IEEE Symposium","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128373947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This system utilizes a video-based technique. The eye, illuminated by low-level infrared (IR) light, is scanned by a charge-coupled device (CCD) camera with an IR pass filter. IR light enters the pupil, is reflected off the retina and comes out through the pupil. The pupil image appears as a larger half-lighted disc against a darker background, called the bright eye. Its position moves in the camera field, following the motion of the eye. A fraction of the IR light is reflected off the corneal surface. This appears in the camera field as a small, intense area called the glint. The method does not need any sensors attached to the user's face, and allows free head movement.<<ETX>>","PeriodicalId":439237,"journal":{"name":"[1991] Computer-Based Medical Systems@m_Proceedings of the Fourth Annual IEEE Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129946275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The expert analyzer then assigns jobs to available processors in such a fashion that the computational load is distributed equally among processors. The processors compute the dose in parallel and deliver final results to the users.<<ETX>>","PeriodicalId":439237,"journal":{"name":"[1991] Computer-Based Medical Systems@m_Proceedings of the Fourth Annual IEEE Symposium","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123918537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An outline of the features of the speech board is presented, and its user interface and its interface with the current PDMS hardware and software discussed. A prototype version of the voice data-entry unit is being tested with the PDMS for the entry of fluid balance data at the patient bedside. By providing a more natural means of manually entering data, the use of speech recognition and generation in intensive care units looks promising.<<ETX>>","PeriodicalId":439237,"journal":{"name":"[1991] Computer-Based Medical Systems@m_Proceedings of the Fourth Annual IEEE Symposium","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128198702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The diagnostic accuracy of the program was compared with that of emergency room physicians. For 132 patients, the difference between the correct diagnosis by the computer program (72%) and by the physicians (79%) was not significant. The computer program distinguished myocardial infraction (MI) from other diseases as well as the physicians (93% vs. 84%), and made fewer false diagnoses of MI; however, it misdiagnosed more cases of angina. Although the computer did not distinguish among cardiac illnesses as well as the physicians, it is thought to be helpful to medical personnel in isolated locations.<<ETX>>","PeriodicalId":439237,"journal":{"name":"[1991] Computer-Based Medical Systems@m_Proceedings of the Fourth Annual IEEE Symposium","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116029205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A detection method based on textural differences between perfused and nonperfused regions is described. The image is tessellated into a large number of primary regions using the positions of major vessels. For each region the degree of nonperfusion is estimated by measuring textural properties using mathematical morphology. The image is represented as a region adjacency graph. Adjacent regions are subsequently merged using information on the degree of perfusion. Comparison with manual grading is presented. It is shown that the algorithm for tessellating the image into regions conforms well to the manual delineation of nonperfused regions. The only parameter in the algorithm selects what size of vessels are used for region detection. The features used for grading the images are sensitive enough to detect nonperfused regions.<<ETX>>","PeriodicalId":439237,"journal":{"name":"[1991] Computer-Based Medical Systems@m_Proceedings of the Fourth Annual IEEE Symposium","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115807670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This discrete variable was obtained for each neonate on the basis of the presence or absence of overt cardiovascular disease, elevated BP, or obesity across two generations. Results indicate that the best model includes the circadian amplitudes of systolic and diastolic BP and the circadian ranges of systolic BP and HR.

An object-oriented and landmark-based registration and integration scheme that fulfils these goals is described. Landmarks are chosen for image registration and atlas integration. The registration approach, which treats images as elastic materials, uses Gaussian radial basis functions. Registration is both simple and efficient and can be applied to both 2-D and 3-D imagery. Sets of landmarks, called frame points, allow new images to be integrated into the DBA through an existing parent image (2-D or 3-D). A web structure is used to track and update the information needed in the registration and integration process.
