Ultrasonic color blood flow imaging control method

Abstract

The invention provides an ultrasonic color blood flow imaging technology in order to improve the frame frequency of ultrasonic color blood flow and output a blood flow velocity diagram with undamaged resolution. Firstly, a color blood flow emission control mode is set based on emission scanning density parameters, that is, a corresponding emission control working mode is formed along with the change of scanning density levels; wherein the scanning density is set to be multi-stage adjustable, each stage corresponds to one emission working mode, and different working modes have different emission scanning line distances. Then, according to the received echo data, virtual receiving line data is constructed according to the corresponding distance between the emission scanning lines to form a new receiving data set; and finally, corresponding post-processing is performed on the new received data, and an image is interpolated and output. Experimental verification shows that especially for some platforms with limited logic resources, storage resources and transmission rate, the method for increasing the distance between the emission scanning lines and constructing the virtual receiving line data can not only improve the color blood flow imaging frame rate, but also ensure that the resolution of the image is not influenced.

Description

technical field [0001] The present invention relates to the field of ultrasonic color blood flow imaging, especially relates to the front-end control transmission mode of ultrasonic color blood flow and the extended reconstruction of received data, aiming to improve the frame rate of color blood flow imaging while retaining the resolution of the original image . Background technique [0002] As one of the four major medical imaging technologies, ultrasound imaging technology has been widely used due to its non-invasiveness, safety and convenience of real-time detection of patients. Ultrasound imaging relies on a powerful imaging system. The ultrasonic imaging system is mainly composed of ultrasonic probe, high-voltage pulse emission, receiving sound beam forming, overall system control, transmission and buffering, echo post-processing, image display and related processing units. Among them, the emission control is to generate short pulse mechanical waves (1~16MHz) through ...
