Abstract
In an ultrasonic scanning and display system, lines of pixel values to be displayed comprise pixel values resulting from reception of echoes separated by pixels for which no echo information was received. The 'holes' between pixels representing echo information are selectively filled in with interpolated values when the length of the sequence of holes is less than a selected number, and sequence of holes greater than the selected number are blanked for display. This arrangement permits the system operator to select the degree to which the display contains interpolated information.
