Abstract
Noise is reduced in the television display of an A trace in an ultrasonic scanner system by integrating digital data representing the magnitude of video signals corresponding to the echos of ultrasonic pulses. The digital integration is accomplished on a point by point basis by summing digital data with stored digital data from previous video signals. Preferably, a capture memory is utilized with a digital summer for integrating the data while another memory periodically receives the integrated data and functions to refresh the television display. In another embodiment, two memories can alternate in capturing the integrated data and in refreshing the display.
