Embodiment Construction

[0049] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0050] Since the advent of Computed Tomography (CT) equipment, the imaging technology has developed extremely rapidly and the equipment has been continuously updated. In medicine, it is used to diagnose spinal and head injuries, intracranial tumors, blood clots in the brain, soft tissue injuries, gastrointestinal diseases, malignant lesions of the waist and pelvis, etc. The basic process of its imaging includes: X-rays are emitted from the focal position of the CT tube and pass through the human body to reach the detector; the detector receives the X-rays passing through t...

Abstract

A CT preview image reconstruction optimization method, an apparatus, a compute device and a storage medium are disclosed. The method comprises the following steps: acquiring scanning parameters; Determining a scan field interval and a total number of scan fields based on the scan parameters; Determining bed position information for all of the scan fields based on the scan parameters, the scan field interval and the total number of scan fields; Acquiring scan data; A preview image is reconstructed based on the scan data and the bed information to obtain a reconstructed preview image. A CT preview image reconstruction optimization method device, computer device and storage medium, by a method of image reconstruction based on bed position information of all fields of view at the start of a scan, At the beginning of the scan, the reconstruction algorithm can start to compute, which greatly improves the reconstruction speed of the first image, shortens the time of the first image, and makesthe time of the first image meet the performance requirements of the CT system.

Description

technical field [0001] The present application relates to the technical field of image reconstruction, in particular to a CT preview image reconstruction optimization method, device, computer equipment and storage medium. Background technique [0002] Since the advent of Computed Tomography (CT) equipment, the imaging technology has developed extremely rapidly and the equipment has been continuously updated. In medicine, it is used to diagnose spinal and head injuries, intracranial tumors, blood clots in the brain, soft tissue injuries, gastrointestinal diseases, malignant lesions of the waist and pelvis, etc. The basic process of its imaging includes: X-rays are emitted from the focal position of the CT tube and pass through the human body to reach the detector; the detector receives the X-rays passing through this layer and converts them into energy intensity signals; the data acquisition and processing system collects the energy intensity signals , and combined with a ce...
