Interactive quantitative analysis of medical images on a PC- or workstation-based system.

Studies in clinical medicine often demand the quantitative analysis of digital CT and MRI cross-sectional images. In many instances, an important requirement is to perform the analysis on a stand-alone graphic workstation. This paper reports on a versatile image analysis software package which runs on several low-cost personal computers, as well as on high-end UNIX workstations. The software package contains basic display and analysis functions, including split-screen, zooming, and quantitative examination of pixels, density profiles, and regions of interest. It has been employed in a number of (foremost orthopaedic) studies.
