1. A method for adjusting image gain compensation during a transition of an image obtained by an imaging system from a first imaging state to a second imaging state, the first imaging state differing from the second imaging state, and the imaging system equipped with an array of ultrasound transducers and generating the image from reflected ultrasonic waves received by the transducer array from a medium of interest, the method comprising the steps of:
determining at least one first image power value based on at least one image acquired in the first imaging state with a first image gain compensation;
determining at least one second image power value based on at least one image acquired in the second imaging state with an initial second image gain compensation;
determining at least one image power change value based on said first image power value and said second image power value;
determining at least one adjusted second image gain compensation based on said initial second image gain compensation and said image power change value; and
recording the at least one adjusted second image gain compensation in a memory.
