Embodiment Construction

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0052] As described in the related art, the Doppler imaging technology can provide one or more sampling windows in real time, so as to measure the speed or direction of blood flow and tissue more conveniently. However, the width of the ultrasonic beam emitted by the current technology cannot cover the full scanning area, so the position of the sampling window cannot be selected arbitrarily; at the same time, when measuring the blood flow velocity and direction, because the actual velocity va...

Abstract

The invention discloses a Doppler spectrum imaging method, device and equipment and a storage medium, ultrasonic signals are transmitted at multiple deflection angles, so that each time of ultrasonic scanning can cover the whole area, and sampling windows at any different positions can be selected; the method comprises the steps of receiving an ultrasonic signal, receiving a plurality of echo signals corresponding to the ultrasonic signal, and generating Doppler spectrums corresponding to a plurality of deflection angles in a target region of interest according to the plurality of echo signals, and because the echo signals also correspond to a plurality of deflection angles, a user does not need to manually detect an included angle between a probe and a wave beam; therefore, the measurement accuracy of the hemodynamic characteristics is improved; and finally, determining a target Doppler spectrum corresponding to the optimal deflection angle, and displaying the target Doppler spectrum with the best signal to a user, so that the user can check a clearer Doppler spectrum, and the diagnosis difficulty of the user is reduced.

Description

technical field [0001] The present application relates to the technical field of ultrasound imaging, and in particular to a Doppler spectrum imaging method, device, equipment and storage medium. Background technique [0002] In the medical color Doppler ultrasound system, Doppler imaging technology transmits ultrasonic signals to a sampling window at a certain position, and then detects the phase or frequency change of the echo signal, so as to be able to observe the blood flow distribution and blood flow of organs at the sampling window in real time. Dynamic characteristics, thus providing convenience for doctors to diagnose. [0003] At present, Doppler imaging technology can provide one or more sampling windows in real time, so as to measure the speed or direction of blood flow and tissue more conveniently. However, the width of the ultrasonic beam emitted by the current technology cannot cover the full scanning area, so the position of the sampling window cannot be sele...
