1. A method for controlling the generation of a compound ultrasonic image, the method comprising:
obtaining a first ultrasound image;
applying adaptive beamforming to the first ultrasound image, thereby generating a second ultrasound image;
determining a weighting based on the first and second ultrasound images, wherein the weighting comprises at least one weighting component; and
generating the compound ultrasound image based on the first and second ultrasound images and the at least one weighting component wherein the at least one weighting component and the generating of the compound ultrasound image are depth-dependent, wherein the method further comprises:
applying a low pass or speckle smoothing filter to the first and second ultrasound images, thereby generating a first image approximation and a second image approximation;
generating a first detail image, based on the first image approximation and the first ultrasound image; and
generating a second detail image, based on the second image approximation and the second ultrasound image.
