Abstract
An ultrasonic diagnostic apparatus includes a physical quantity calculator for setting correlation windows to echo signals via ultrasound of a biological tissue and lying on the same sound rays which belong to frames different in time, and performing a correlation arithmetic operation between the correlation windows to calculate a physical quantity related to elasticity of the biological tissue, and an elastic image data generator for generating elastic image data of the biological tissue, based on the physical quantity. Upon setting each correlation window to the echo signal on one sound ray which belongs to either one of the frames, the physical quantity calculator sets the each correlation window using a correlation arithmetic operation on an immediately preceding correlation window adjacent to the correlation window on one sound ray and previously subjected to a correlation arithmetic operation, and a correlation arithmetic operation on another sound ray correlation window.
