Abstract
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 the ultrasonic image is provided. The first digital signal is companded to form a second digital signal, the second digital signal being stored. The companding provides a second digital signal which is a non-linear function of the first digital signal such that the granularity of the stored signal is increased in regions of high diagnostic interest at the expense of decreased resolution in areas of low diagnostic interest. When it is desired to display the stored digital image, the second digital signal is retrieved from the storage means and decompanded to provide the reconstituted first digital signal which is thereafter directed to a video display.
