Abstract

The invention discloses a fluid Doppler parameter determination method and electronic equipment. In the embodiment of the invention, the clutter is firstly removed through the clutter removal operation, and then the feature information of the envelope curve of the fluid is adopted to obtain the search threshold suitable for the envelope curve, so that the determination of the search threshold can conform to the own features of the envelope curve, the search threshold can be passed without prior information, and a fluid mutation region from the envelope curve is accurately extracted. Then, a systolic period peak flow velocity position can be extracted in the fluid mutation area, and a diastolic period end peak flow velocity position is further extracted from the envelope curve in combination with preset features of a diastolic period end peak. In the application, the preset feature of the end peak of the diastolic period is obtained through data analysis and expert experience, and can be suitable for the characteristics of the fluid, so that the flow velocity position of the end peak of the diastolic period can be accurately extracted based on the feature.

Description

technical field [0001] The present application relates to the technical field of ultrasonic image processing, in particular to a fluid Doppler parameter determination method and electronic equipment. Background technique [0002] In ultrasound systems, the Doppler effect is used to evaluate the dynamic information of blood flow. Ultrasound Doppler can be divided into pulsed Doppler and continuous Doppler. The imaging principle of pulsed Doppler is: in the form of pulse waves, ultrasonic waves are transmitted into the blood flow area, and the ultrasonic system receives ultrasonic echo data. The ultrasonic system continuously transmits and receives according to the specified time interval, so as to obtain ultrasonic echo signals that change with time, and perform spectrum analysis on these ultrasonic echo signals to obtain a time-varying spectrum image. In the spectrum image, the horizontal direction represents time, and the vertical direction represents blood flow velocity ...
