Abstract

The invention discloses an image reconstruction method and device based on a computer tomography imaging system. The method comprises steps of acquiring acquisition parameters in a scanning protocol, and determining reconstruction parameters used for image reconstruction according to the acquisition parameters; according to the acquisition parameters and / or reconstruction parameters, determining a target reconstruction algorithm and according to the target reconstruction algorithm, generating a reconstruction protocol; and based on the acquisition parameters, acquiring scanning data of a to-be-detected object, and according to the scanning data and the reconstruction protocol, carrying out image reconstruction. According to the invention, through the acquisition parameters and the reconstruction parameters, the target reconstruction algorithm is determined, so linkage between the reconstruction parameters and the acquisition parameters can be achieved; according to the target reconstruction method, a reconstruction protocol adaptable to the current scanning protocol is generated, so problems of algorithm idling and repeated calculation of parts of algorithms caused by use of fixed parameters and fixed topology structures in the current reconstruction protocol are overcome and efficiency of image reconstruction is effectively improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular to an image reconstruction method and device based on a computed tomography system. Background technique [0002] When taking medical images, the computerized tomography system (Computed Tomography, CT) will scan the patient according to the scanning protocol with pre-set acquisition parameters, scan the patient's scanning data, and then perform data processing on the scanning data according to the reconstruction protocol. processed to form medical images that assist doctors in making diagnoses. [0003] At present, in the process of image acquisition, the default factory scan protocol and default parameters can be selected according to the selection of the operation interface in the CT system, and the parameters that can be adjusted in the interface can also be modified, such as whether to use metal removal, etc., and then the CT system will Pass...
