| 6. A method of compensating for variations in the velocity of sound in different media in the analysis of ultrasound images,
wherein an ultrasound transducer system is used to acquire ultrasound images, the method comprising the steps of:
acquiring a set of A-scan ultrasound images;
shifting each A-scan along its time axis so that the position of surface peaks for becomes the same for all ultrasound transducer
channels;
building a C-scan image from the A-scan images, wherein the C-scan image reflects the shifting; and
displaying the C-scan image.
