[0023] In the present invention, a method for automatically optimizing Doppler imaging parameters is provided. now refer to image 3 The main flowchart of the method for automatically optimizing Doppler imaging parameters according to the present invention is shown to describe the present invention in detail.
[0024] The method for automatically optimizing Doppler imaging parameters according to the present invention starts at step 300 and ends at step 360 . In order to eliminate multiple aliasing as much as possible, first at step 305, the pulse repetition frequency is set to the maximum pulse repetition frequency value at the current detection depth, and the set pulse repetition frequency is provided to the ultrasonic transmitting unit. Assuming that d is the current detection depth, and c is the propagation speed of ultrasonic waves in the human body, then the maximum pulse repetition frequency at the current detection depth is defined as:
