Abstract
PURPOSE:To enhance blood measuring accuracy and operability by automatically tracking the movement of an arbitrarily turned blood vessel in an arbitrary direction, by taking an intracorporeal tomographic image simultaneously with the measurement of blood flow and tracking a blood vessel on the taken tomographic image to set a blood flow measuring point to the interior of the blood vessel. CONSTITUTION:In the tomographic image 1 of a human body by an ultrasonic diagnostic apparatus, a density value is lowest at the center of a blood vessel part 2 and becomes higher as approaches the wall of the blood vessel. Therefore, a searching region 4 containing the blood vessel part 2 is provided centering around a blood flow measuring point 3 and, when the projection data 5 is calculated, the projection data value in the vicinity of the center part of the blood vessel becomes lowest. Herein, the point 7 in the blood vessel can be detected from coordinates 6 where the value of the projection data 5 becomes min.
