A medical diagnostic imaging system generates a compounded beam signal C by combining first and second beam signals B1, B2 subsequent to detection and a synthesized beam signal S by combining the first and second beam signals B1, B2 prior to detection. The compounded signal C and the synthesized signal S are then adaptively weighted in response to a selection signal and combined to form an image signal. In this way, the compounded signal C is made to dominate in regions of the image that benefit from increased contrast resolution and the synthesized signal S is made to dominate in regions of the same image that benefit from increased detail resolution.
