    Notes: Abstract A powerful new microcomputer-based system has been developed which permits detailed investigations and evaluation of 3-D and 4-D biomedical images. The system comprises a network of powerful workstations to which all the information in a large 3-D image data base is accessible for rapid display, manipulation, and measurement. The system supports 3-D imaging modalities based on X ray, radionuclide emission tomography, ultrasound tomography, and magnetic resonance imaging. The system provides important capabilities for simultaneously representing and analyzing both structural and functional data and their relationships in various organs of the body. This paper provides a detailed description of this system, as well as some of the rationale, background, theoretical concepts, and practical considerations related to system implementation and applications.

    Notes: Summary A method is described for reproducible and rapid quantitative measurements of fractional bone volume in sections of a bone biopsy. The presence or absence of bone is determined at several thousand points over the entire surface area of each specimen by highspeed digitization and computer analysis of video scans of enlarged microradiographic images of bone sections. An operator interactive light-pen assembly permits selective delineation of desired areas of the video image to facilitate computation of regional bone mass within each specimen. Tests of the reproducibility of the method were performed and are described. The results obtained from application of the method to determine the amount of bone in various age groups and in two groups of patients before and after therapy are also presented. These data indicate the potential of this technique for high volume, high resolution measurements of the fractional bone volume in both investigative and clinical diagnostic studies of age dependent and disease dependent processes.
