Abstract

The invention relates to a CT image generation method, device and system, an electronic device and a storage medium, and the method comprises: obtaining a first overlapped image in a first shot image set, and a second overlapped image in a second shot image set, wherein the scanning frame number of the first shot image set is adjacent to that of the second shot image set, and the position information of the first overlapped image is the same as that of the second overlapped image; calculating a deformation vector field according to the first overlapping image and the second overlapping image; and performing registration processing on the first shot image set and the second shot image set by using the deformation vector field to generate a target CT image. According to the invention, the phenomenon of layer staggering between CT images generated by two adjacent times of scanning is avoided, and the problem that the CT images are discontinuous at the boundary of the scanning area is solved.

Description

technical field [0001] The present application relates to the technical field of CT images, and in particular to methods, devices, systems, electronic devices and storage media for generating CT images. Background technique [0002] CT images acquired by using computerized tomography (Computed Tomography, CT for short) are widely used in the diagnosis of diseases, the study of organ functions, and the like. CT has two modes of axial tomography and helical scan, each of which has different clinical use scenarios. When the axial tomography mode is used to scan an object in a large area, it is necessary to perform multiple radial scans. The bed remains still during each radial scan, and the bed is moved after one scan is completed, and the radial scans are performed sequentially. Here During the CT scanning process, if the object moves, or the hospital bed is deformed, or even the direction of entering the bed is not strictly perpendicular to the CT gantry, these will cause mi...
