Medical image processing method and device, computer equipment and storage medium

Abstract

The invention discloses a medical image processing method and device, computer equipment and a storage medium. The medical image processing method comprises the steps that contour data and a contour data range of a target object are acquired; contour points in the contour data are reconstructed, reconstructed grid contour data are obtained, and normal vectors of the contour points in the reconstructed grid contour data are in the unified direction; according to the contour data range, deleting grids not in the contour data range in the reconstructed grid contour data to obtain adjusted contour data; and according to the adjusted contour data, topology is reorganized, and a reconstructed medical image is obtained. According to the embodiment of the invention, the pseudo curved surface and the corresponding grid in the contour data range can be quickly and efficiently deleted, the adjusted contour data is recombined to obtain the reconstructed medical image, the reconstruction algorithm does not need to be improved while the pseudo curved surface is deleted, the image processing efficiency is improved, and the image quality is improved. And the subsequent operation is not influenced.

Description

technical field [0001] The present application relates to medical technicians and the field, and in particular to a medical image processing method, device, computer equipment and storage medium. Background technique [0002] In modern medicine, in order to obtain better information on lesion parts in the patient's body, three-dimensional imaging techniques are usually used according to target information of specific target parts, for example, three-dimensional CT images are constructed according to target information. [0003] When delineating images of delineated objects (such as the brain, lungs, etc.) With a large opening, at this time, if the contour surface after the three-dimensional reconstruction of the target object will contain redundant surfaces at its edges, it can also be called a pseudo-surface. These redundant surfaces exist in the reconstructed image, which hinders the acquisition of effective information in the image. [0004] Specifically, for medical co...

However, the surface, especially the two-dimensional manifold surface represented by triangles, is a topological space structure. In addition to containing the indices that make up the triangles, there are also points pointed to by these indices. If you simply delete the indices that make up the triangles, the pseudo-surface The point still exists, not only increases the storage memory, but also affects the operation of the subsequent surface
