Abstract
An ultrasonic blood flow imaging method includes: transmitting first, second and third ultrasonic waves to a to-be-measured blood flow position of a target object at a first transmitting angle to acquire a first projection component of a blood flow velocity vector, with a first pulse repetition frequency between the first ultrasonic waves and the second ultrasonic waves and a second pulse repetition frequency between the second ultrasonic waves and the third ultrasonic waves; transmitting fourth, fifth and sixth ultrasonic waves to the to-be-measured blood flow position at a second transmitting angle to acquire a second projection component of a blood flow velocity vector, with a third pulse repetition frequency between the fourth ultrasonic waves and the fifth ultrasonic waves and a fourth pulse repetition frequency between the fifth ultrasonic waves and the sixth ultrasonic waves.
