ABSTRACT:
An improved still or frozen picture is provided in an ultrasonic sector scanner by generating and displaying two frames. The first frame is identical to the frame generated for dynamic real-time display. The second frame is generated from vectors lying intermediate vectors of the first frame with the same reflected signal data applied thereto. Accordingly, the pixel data is doubled in the still or frozen picture.
