Abstract
Microcomputer-based image processor boards are now available that allow a personal computer to be used as a powerful image processing system. Such systems can be used in ultrasound imaging by “grabbing,” i.e., digitizing frames of video information at the video output of the ultrasound imager. This paper describes one such system which incorporates an IBM PC, a commercially-available frame-grabber board and associated software to capture and analyze images obtained using an Acuson ultrasound system. Preliminary results obtained with this system are presented. Potential applications include image filtering, processing and enhancement, precise analysis of images including image histograms, geometric operations to expand or reduce regions of interest or to correct distortions, and comparison of digital files obtained from the same patient over time.
