PROBLEM TO BE SOLVED: To improve operability in oblique scanning.SOLUTION: An ultrasonic diagnostic apparatus comprises scan means, tomographic image data generation means, spectrum image data generation means, display control means, movement means and angle change means. The scan means scans a cross-sectional plane with first and second ultrasonic beams. Each data generation means generates tomographic image data and spectrum image data on the basis of a reception signal obtained for each scan. The display control means causes a display section to display a screen that contains a tomographic image and a Doppler spectrum image corresponding to respective data with a range gate marker arranged on the tomographic image. The movement means moves a range gate position by moving the marker. The angle change means changes an inclination angle of a second ultrasonic beam with respect to a normal direction of a probe surface such that the range gate position is included in a scannable region of the second ultrasonic beam when the range gate position is moved outside the scannable region thereof. |
