Abstract
An ultrasonic imaging system and method is described in which the actual dimensions of images of tissue acquired with a moving transducer (22) are displayed. Since an image is distorted based upon the direction a transducer probe moves relative to the acoustic scanning direction of the transducer (22), the probe motion direction and the acoustic scanning direction are initially determined. If the probe is moving in the same direction as the scanning direction, the acoustic beam scanning speed of the moving probe relative to the tissue is determined by summing the acoustic beam scanning speed without probe motion with the probe speed. If the probe is moving in the opposite direction as the scanning direction, the acoustic beam scanning speed of the moving probe relative to the tissue is determined by taking the difference between the acoustic beam scanning speed without probe motion and the probe speed. The actual width of the image as represented in each pixel of a frame (32) acquired while the probe is moving is derived based upon a ratio of the acoustic beam scanning speed of the moving probe relative to the tissue to the acoustic beam scanning speed without probe motion. Finally, the actual dimensions of the image are displayed based upon the derived width of the image as represented in each pixel of the frame (32).
