Abstract
An ultrasonic imaging system and method provide whitening using a two dimensional pre-detection filter followed by low pass filtering using a two dimensional post-detection filter to reduce speckle variance and enhance spatial resolution of the resulting image. The amplitude of the whitened signal can be adjusted as a function of variance or gradient of the ultrasonic receive signal to reduce undesired side lobes.
