PROBLEM TO BE SOLVED: To display an ultrasonic color image with excellent image quality by reducing noise.SOLUTION: An ultrasonic diagnostic device includes a scan means, a speed calculation means, a correction means, and an image generation means. The scan means transmits/receives an ultrasonic wave to/from a subject and collects multiple blood flow Doppler signals as complex signals. The speed calculation means obtains the speed of a blood flow, based on the blood flow Doppler signals. The correction means corrects the speed of a blood flow with vector calculation for calculating the speed of a blood flow by the unit of multiple vectors on a complex plane and with return correction of the speed. The image generation means generates blood flow image data, based on the speed of a blood flow after correction. |
