Ultrasonic contrast imaging method, device and equipment and readable storage medium

Abstract

The invention provides an ultrasonic contrast imaging method. The method includes: performing feature point extraction and feature point matching according to two continuous frames of volume data to obtain a plurality of matching feature points; obtaining an affine matrix, multiplying the voxel value corresponding to each voxel point of the second volume data by the affine matrix to obtain each corresponding individual data value; subtracting the individual data value from the voxel values of the voxel points of the first volume data point by point to obtain a plurality of voxel difference values; and obtaining a difference region according to the voxel difference value, extracting the difference region of the new second volume data by using an iterative processing mode, completing the extraction of the difference region of all volume data, and filling different colors in each difference region to obtain an ultrasound contrast imaging image. According to the invention, the flow direction and process of the contrast agent can be clearly and visually displayed, and a more real contrast image can be obtained, so that a doctor can be better assisted in diagnosis. The invention furtherprovides an ultrasonic contrast imaging device, ultrasonic contrast imaging equipment and a readable storage medium which all have the above beneficial effects.

Description

technical field [0001] The present application relates to the technical field of contrast-enhanced ultrasound, and in particular to a contrast-enhanced ultrasound imaging method, a contrast-enhanced ultrasound imaging device, a contrast-enhanced ultrasound imaging device, and a computer-readable storage medium. Background technique [0002] Ultrasonic contrast (ultrasonic contrast) is a technique that uses contrast agents to enhance backscatter echoes and significantly improve the resolution, sensitivity and specificity of ultrasonic diagnosis. In the uterus and fallopian tubes, the contrast agent is injected into the uterus and fallopian tubes through a catheter placed in the official cavity to display the shape and position of the uterine cavity and fallopian tubes, so as to detect uterine cavity and fallopian tube lesions and deformities and evaluate the patency of the fallopian tubes. The three-dimensional contrast-enhanced ultrasound images obtained in the prior art can...

AI Technical Summary

Problems solved by technology

The three-dimensional contrast-enhanced ultrasound image obtained by the prior art cannot clearly show the flow direction and process of the contrast agent, so the three-dimensional contrast-enhanced ultrasound image cannot clearly reflect the real contrast image
