Abstract:
1. An apparatus for measuring velocity of an ultrasound signal, comprising: a transmitting module transmitting ultrasound signals to targets; a receiving module receiving the ultrasound signals reflected from the targets; an image generating module using the received ultrasound signals to generate a plurality of ultrasonic images having different sound velocities; and a sound velocity determining module using the plurality of generated ultrasonic images to determine optimal sound velocity for scanning the targets, wherein the sound velocity determining module comprises: wherein the sound velocity determining unit detects the edge regions of blocks selected for each ultrasonic image, sums the luminance of the detected edge regions, and compares the luminance of the edge regions summed for each ultrasonic image to determine the sound velocity of the ultrasonic images having the smallest luminance in the summed edge regions as the optimal sound velocity for scanning the targets.
