Abstract
A method for High Pulse Repeat Frequency (HPRF) Doppler ultrasonic imaging comprises: collecting parameters including a selected PRF level, real sample volume depth and sampling gate size; setting a selectable PRF range according to a standard PRF value corresponding to the selected PRF level; evaluating each PRF successively selected from the selectable PRF range with a preset step; and taking the PRF with best evaluation as the best PRF of the selected PRF level to be used in ultrasonic pulses transmission.
