Abstract
An ultrasonic diagnosis apparatus, in which an ultrasonic image of a diagnostic region of an object having flows of blood is formed, utilizes a Doppler shift for calculating a blood flow amount. For example, first, a plurality of ultrasonic beams are trasnmitted for the diagnostic region and echo signals of the beams are received for forming the ultrasonic image and obtaining Doppler shifts. A measuring line intersecting the flows of blood is delineated on the ultrasonic image. The measuring line orthogonal with the blood flows is preferred. For example, Doppler shift frequancies of the blood flows at measuring points designated on the measuring line are inferred on the basis of the echo signals of Doppler shift already obtaind and memorized. The measuring points are imaginary points in such a case. Using the Doppler shift frequencies of the blood flows, a total amount of blood flows is calculated.
