Title:
THREE-DIMENSIONAL MRA MEDICAL IMAGE SPLICING METHOD AND APPARATUS, AND ELECTRONIC DEVICE AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/012520
Kind Code:
A1
Abstract:
Provided are a three-dimensional MRA medical image splicing method and apparatus, and an electronic device and a computer-readable storage medium, belonging to the technical field of medical image processing. The method comprises: performing Laplace denoising, enhancement and irregular smoothing processing on two adjacent three-dimensional MRA medical images to be spliced that are received in real time, in order to obtain a first image and a second image; performing overlapping layer detection on the first image and the second image to determine a first overlapping region in the first image and a second overlapping region in the second image; and performing, by using a weighted average method, fusion splicing processing on the first overlapping region and the second overlapping region to obtain a third image after fusion splicing. In the present application, overlapping layer detection is respectively carried out on two pre-processed adjacent three-dimensional MRA medical images to be spliced, overlapping regions in the two three-dimensional MRA medical images to be spliced are determined, and the two overlapping regions are then fused and spliced, so that the efficiency of the determination of an overlapping region in an image can be improved, thereby improving the image splicing efficiency.
