Embodiment 1

[0027] figure 1 It shows the implementation process of a three-dimensional ultrasonic reconstruction method provided by Embodiment 1 of the present invention. For the convenience of description, only the parts related to the embodiment of the present invention are shown, and the details are as follows:

[0028] In step S101, when receiving stack images scanned by multi-angle ultrasound, set the stack image with the smallest motion error among all stack images as the template stack image, and globally align the remaining stack images in all stack images with the template stack image allow.

[0029] The embodiment of the present invention is applicable to a three-dimensional ultrasound system. Ultrasonic scanning is performed at different angles to obtain a sequence of two-dimensional ultrasonic images scanned at different angles (ie, a sequence of two-dimensional slices). The sequence of two-dimensional ultrasonic images at the same angle can be called a stack image. A method...

Abstract

The present invention is applicable to the field of computer technology, and provides a three-dimensional ultrasonic reconstruction method, device, equipment, and storage medium. The method includes: setting the stack image with the smallest motion error among stack images scanned by multi-angle ultrasound as a template stack image, Globally register the remaining stack image with the template stack image, construct 3D volume data based on the remaining stack image and the template stack image, update the 3D volume data by volume reconstruction based on kernel regression function, and judge the updated 3D volume data Whether it is converged, if yes, perform local registration of the remaining stack images, template stack images and 3D volume data, otherwise jump to the step of updating the 3D volume data, and judge whether the 3D volume data after local registration is converged, if yes, then Output the 3D volume data after local registration, otherwise jump to the step of constructing 3D volume data, thereby realizing 3D ultrasound reconstruction based on multi-angle scanning, effectively improving the reconstruction quality of 3D ultrasound images.

Description

technical field [0001] The invention belongs to the technical field of medical images, and in particular relates to a three-dimensional ultrasonic reconstruction method, device, equipment and storage medium. Background technique [0002] The three-dimensional ultrasound system can intuitively provide doctors with the spatial position and three-dimensional shape of organs or tissues of interest in the body, and more accurately reflect the shape, volume, contour, and adjacency between organs in clinical practice. At present, three-dimensional ultrasound systems mainly include two categories. One is the volumetric imaging method based on a two-dimensional area array probe (also known as a volumetric probe dedicated to three-dimensional ultrasound). The device drives the chip to do equidistant sector scan or circular scan. The other is to use traditional two-dimensional ultrasound equipment combined with specific spatial positioning information to obtain a sequence of two-dimens...
