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 invention provides a three-dimensional ultrasound reconstruction method and device, equipment and a storage medium, which are suitable for use in the technical field of computers. The method comprises: setting a heap image of a smallest motion error in heap images, which are scanned by multi-angle ultrasound, as a template heap image, and carrying out global registration on the remaining heapimages with the template heap image; constructing three-dimensional body data according to the remaining heap images and the template heap image; updating the three-dimensional body data through a kernel reconstruction function-based body reconstruction manner, and judging whether the three-dimensional body data after updating converge; if yes, carrying out local registration on the remaining heapimages and the template heap image with the three-dimensional body data, and otherwise, jumping to the step of updating the three-dimensional body data; and judging whether the three-dimensional bodydata after local registration converge, if yes, outputting the three-dimensional body data after local registration, and otherwise, jumping to the step of constructing three-dimensional body data. Therefore, three-dimensional ultrasound reconstruction based on multi-angle scanning is realized, and reconstruction quality of a three-dimensional ultrasound image is effectively improved.

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...
