Abstract

In an illustrated embodiment the line generator for the image display device is operated at a relatively high frequency such as 200 Hz while the actual ultrasonic scanning takes place at a pulse repetition rate of 50 Hz. Preferably alternately operable buffer memories store successive lines of ultrasonic echo signals, and then provide readout of the lines at a higher rate consistent with the display line frequency. In the example given, each stored echo line is read out twice in successive display line intervals. By suitable control of the readout timing, one set of staggered pairs of display lines may be displayed during one image cycle, and an interleaved set of display line pairs may be activated during alternate image cycles in conjunction with interlaced scanning operation of the ultrasonic applicator.
