We present a method for medical image understanding by computer that uses model-based, hierarchical Bayesian inference to accurately segment imaged anatomy. A first application is a prototype system that automatically segments and measures symptoms o

We assessed the ability of 31phosphorus (31P) transrectal magnetic resonance spectroscopy to characterize normal human prostates as well as prostates with benign and malignant neoplasms. With a transrectal probe that we devised for surface coil spect

In this study we use a strong model of the center of the phalanx in hand radiographs to predict continuation of the phalanx boundary. The center phalanx is robustly segmented using conventional approaches. Estimating tangents allows us to find the mi

Large scale feature searches of accumulated collections of medical imagery are required for multiple purposes, including clinical studies, administrative planning, epidemiology, teaching, quality improvement, and research. To perform a feature search

The transition from analog film-based to electronic imagery management in radiology departments and clinics requires accurate projection of storage and network capabilities. We previously developed a method of estimating from film usage, static stora

Model-based reasoning techniques complement traditional image processing and pattern recognition to compensate for the ambiguities inherent in medical imagery data. In model- based reasoning, higher-order image features, such as inferred surface boun

A medical imagery database should be complete, accurate, secure, and functionally robust. Database completeness depends on availability of medical imagery in digital format. A PACS should incorporate all medical imagery, including not only standard x

For PACS to be clinically desirable, transmiued imagery must be optimized for the various clinical and research tasks. There are several processes that potentially degrade the diagnostic utility of the iransmitted imagery. We examined our CommView PA

PACS offers new capabilities, but presents some new limitations as well. We reviewed radiology practice at four medical centers. For interpretation of new images, most radiologists felt that the most recent examination for comparison would suffice, e
