Paper Abstract

Much of the information in real-time ultrasonic imaging examination is lost when only a few of the scan planes are recorded. Recording of all scan planes is particularly desirable in the examination of the breast, where there are few anatomical landmarks and discovery of small lesions leads to the best prognosis. We have developed a system, that allows such recording and provides for playback in a very flexible manner; the images can be reviewed at a rate from zero (static) to 30 frames per second, forward or backward, with 'instantaneous" reversal or stopping in the progression of images under review. The images are stored as two rings of 120 images each, one ring per breast, on a disc of photographic material. The developed disc is placed in a reader which spins it at a constant 60 rev/sec. By counting the timing marks recorded along with the images (obviating tight mechanical tolerances) any selected image can be flashed onto a TV camera by a strobe unit controlled by the timina-mark count. As there is no mechanical inertia, the rate of change in the selected image can proceed at any rate up to the monitor and is applicable for use with formatters, VTR, etc. , for further image recording. The recording disc is small (8 diameter.) and inexpensive (<$5) and provides an archival unit record for inclusion in patient files.
