The system operates on images using the method of dynamic contrast-enhanced MRI. Suspicious breast lesions are automatically marked with colours, thus directing the physician's attention towards the critical regions. A proper and careful decision procedure is needed to differentiate between increases of signal intensity triggered by noise and tissue dislocations (motion artifacts) and increases that are triggered by an accumulation of contrast agent in the related breast region. We present our component for image matching using self organising maps (SOM), which enables the system to work properly even with image sequences that are strongly deformed by the patients breathing movements. To reach the time constraint of 15 minutes in medical practice we decide to implement a parallel architecture for the neural network matcher, which works on all computers in the heterogeneous network of our medical partners. The system is tested on real patient data and is now being refined in cooperation with our partner hospital for Radiology and Nuclear Medicine in Mainz.","PeriodicalId":189930,"journal":{"name":"Proceedings 13th IEEE Symposium on Computer-Based Medical Systems.

The set-up for acquiring data is a small wearable personal computer (WPC) assisted system. It employs a lithium battery-powered gyro-sensor. While walking, the WPC is worn like a wrist-watch, the small sensor is fixed to the person's back, near the body's centre of gravity, and the batteries are inserted into a waist pouch. When the WPC switch is turned on, three relative angles (i.e. roll, pitch and yaw) and accelerations in the X, Y and Z axes of the person's back are recorded at 30 Hz. People who wear dentures were selected as subjects at the department of geriatric dentistry in a dental hospital. It was observed that, in the case of people wearing dentures, the angular displacements and the accelerations of the back in walking had a better rhythm compared to those without dentures. As an effective analyser system for walking stability, power spectral analysis is used, utilizing autoregressive modelling. In the case of people not wearing dentures, their power spectrum densities of the three angles and accelerations of back fluctuation were wavy, showing unstable walking. In the case of people wearing dentures, their power spectrum densities were approximately close to a 1/f/sup 3/ fluctuation (f = frequency), i.e. they were stable when walking in all directions. Using this WAS, it is easy to discover people's walking stability in rehabilitation and physical fitness.","PeriodicalId":189930,"journal":{"name":"Proceedings 13th IEEE Symposium on Computer-Based Medical Systems.

This resource, the Web-based Medical Information Retrieval System, or WebMIRS, is currently in beta test. In a future WebMIRS system, we plan to have not only text and raw image data, but quantitative anatomical feature information derived from the images and capability to retrieve images based on image characteristics, either alone or in conjunction with text descriptions associated with the images. Our archive consists of data collected in the second and third National Health and Nutrition Examination Surveys (NHANES), conducted by the National Center for Health Statistics. For the NHANES II survey, the records contain information for approximately 20,000 participants. Each record contains about two thousand data points, including demographic information, answers to health questionnaires, anthropometric information, and the results of a physician's examination. In addition, approximately 10,000 cervical spine and 7,000 lumbar spine X-rays were collected. WebMIRS makes the text and images retrievable. Only raw images are returned; no quantitative or descriptive information about the images is stored in the database. We are conducting research into the problem of automatically or semi-automatically segmenting spine vertebrae in these images and determining vertebral boundaries with enough accuracy to be useful in classifying the vertebrae into categories of interest to researchers in osteoarthritis.","PeriodicalId":189930,"journal":{"name":"Proceedings 13th IEEE Symposium on Computer-Based Medical Systems.
