Abstract
A method and apparatus for tissue border detection using ultrasonic diagnostic images includes searching an initial central point of a target region in an ultrasonic diagnostic image of a detected target and determining an initial region border based on the initial central point and with the initial central point being a pole, searching a position of a target region border along a polar line across the pole and from an initial region border, and calculating an energy function of intensity distribution at different positions, wherein a position corresponding to a minimum value of the energy function of the intensity distribution is the border position of the target region.
