A new method for gain correction in ultrasonic imaging.
A system is proposed in which the depth for each ultrasonic image pixel, which is needed for scan conversion, is simultaneously given with the pixel coming out from the digital scan processor. The gain memory is only a line memory with less circuitry and is updated faster when the gain function is modified by the user. The use of the system in routine clinical work shows that post-gain correction capability is an improvement in terms of ease-of-use and image quality optimization.
