Abstract
A digital video recorder is provided which provides digital storage of realtime ultrasonic image sequences, replacing the conventional VCR with a recorder which does not degrade digital ultrasound images by analog conversion and recording. The digital video recorder is operated by softkey controls in a displayed toolbar which are familiar to a VCR user. The virtual controls of the toolbar are selected by a video pointing device to stop, start, control replay speed, and skip to various points in a realtime ultrasonic image sequence which was stored by the digital video recorder.
