  • Method of acquiring ultrasound images
    Patent number: 5181513
    Abstract: Ultrasound images are rendered reproducible over long time periods by determining contours of a first image and superimposing them on a real time display screen during acquisition of a second image. The operator manipulates the probe so that the new image fits within the contours obtained from the first image. This avoids the need for signal processing requiring powerful computer resources. It also avoids the use of complicated ultrasound images. The method may be implemented in any ultrasound equipment currently available on the market.
