Abstract

Pixel data is selectively updated in an ultrasound scanning system in which the monitor display includes a plurality of addressable pixels. A random access memory holds the intensity values for the display pixels, and the memory is updated in response to rescanning of a patient. Updating is inhibited for a pixel of a vector when the preceding vector included the same pixel. Spurious display effects are thereby minimized.
