An improved ultrasonic imaging system and method are provided for medical diagnostic purposes. In order to store additional digital ultrasonic imaging information in a limited memory, a first digital signal representative of a video input signal is provided. The first digital signal comprises a series of digital amplitude samples of the transverse component of the input signal. A second series of samples is provided from the first series. Each element of the second series is the arithmetic average of a group of elements of the first series. The second series of elements is stored. Since the number of elements of the second series is less than the number of elements of the first series, memory density of the transverse component of the input signal is decreased.
