Abstract

The invention is suitable for the technical field of computers, and provides a multi-planar reconstruction method used for CBCT imaging and a multi-planar reconstruction device used for CBCT imaging,equipment and a storage medium. The method comprises the steps that three-dimensional reconstruction is performed on the perspective image scanned by a cone beam CT imaging scanning system so as to acquire the three-dimensional volume data of a projector; the one-dimensional texture and the three-dimensional texture of the three-dimensional volume data are constructed; the texture coordinates of the axial image, the sagittal image, the coronal image and the oblique image of the point to be observed on the three-dimensional texture are calculated; the texture coordinates of a curved image to beobserved on the three-dimensional texture are calculated; and the axial image, the sagittal image, the coronal image, the oblique image and the curved image to be observed are drawn and outputted according to the texture coordinates of the axial image, the sagittal image, the coronal image, the oblique image and the curved image to be observed so that the stereo sense and the integrity of multi-planar reconstruction can be effectively enhanced by drawing different attitudes of two-dimensional images.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a multi-plane reconstruction method, device, equipment and storage medium for CBCT imaging. Background technique [0002] CBCT (Cone beam CT, cone beam CT) imaging technology originated from the DynaCT technology launched by Siemens Medical Systems Group in recent years. Computer reconstruction generates three-dimensional volume data. After the three-dimensional volume data is obtained through CBCT scanning and reconstruction, the three-dimensional volume data is usually displayed by means of multi-plane reconstruction. [0003] Multi-plane reconstruction is a display method of 3D volume data. It is to draw arbitrarily a line on the axial image as needed, and draw the 3D reconstruction image of the line drawing plane. The drawn 3D reconstruction image includes axial image and coronal image. , sagittal images and oblique images at any angle. At present, multi-plan...
