Cine display of numerous static ultrasound images: a step toward automation of ultrasound studies.
Ultrasound images were assembled and viewed in a motion picture format to facilitate the laborious task of reviewing numerous sonograms. Sequential, closely spaced images from an automated water bath ultrasound scanner were recorded both on a video disc recorder capable of high speed playback and on a film strip using a 35-mm half frame camera. A conventional 35-mm cine viewer was used to evaluate the film strip. Advantages of the motion picture format are (a) many images can be reviewed easily and rapidly, (b) objects that extend through several images are easily perceived and an impression of the third dimension is obtained, (c) the chances of diagnostic errors due to wide spacing or selective recording of images are lessened, and (d) fuller advantage can be taken of the scanner's capacity for automatic operation. Disadvantages of the technique are (a) respiratory motion must be minimized, and (b) the method is useful only in conjunction with water bath scanners.
