A method and circuitry are disclosed for displaying the A-Trace of ultrasonic reflections on a video screen. The disclosed system provides means for writing pulse reflection data into memory, and means for selectively accessing the memory to place the data on the screen in graphical form. The data is stored and accessed in a format which is compatible with the scan pattern associated with the video display.
