Embodiment Construction

[0045] 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.

[0046] Computed tomography (CT) generally includes a gantry, a scanning table, and a console for a doctor to operate. A ball tube is arranged on one side of the rack, and a detector is arranged on the side opposite to the ball tube. The console is a computer device that controls scanning, and the computer device is also used to receive the scan data collected by the detector, process and reconstruct the data, and finally form a CT image. When using CT to scan, the patient lies on the scanning bed, and the scanning bed sends the patient into the aperture of the machine fra...

Abstract

The present application relates to an image reconstruction method, an apparatus, a computer device and a storage medium. The method comprises the following steps: obtaining scanning data of all phasesand reconstructing to obtain images corresponding to a plurality of phases as images to be evaluated; Calculating a quality index of each image to be evaluated according to an image quality evaluation rule; According to the quality index of each image to be evaluated, the best phase is calculated and the best phase image is obtained. Independent of the interaction of artificial interface, the blood vessel of interest can be detected and extracted automatically, and the image quality of blood vessel can be analyzed automatically. It not only simplifies the process of coronary artery reconstruction, but also saves the time for doctors to evaluate the parameters of image selection.

Description

technical field [0001] The present application relates to the technical field of medical equipment, in particular to an image reconstruction method, device, computer equipment and storage medium. Background technique [0002] Angiography is an auxiliary examination technology. In the period of advanced technology, angiography technology is widely used in the diagnosis and treatment of various clinical diseases, which helps doctors to detect the disease in time, control the progress of the disease, and effectively improve the survival of patients. Rate. Therefore, the image quality of angiography is very important for diagnosis. [0003] In the current traditional technology, clinically, the quality evaluation of angiography is manual observation and reconstruction of images and subjective evaluation. In coronary angiography, the beating of the heart produces motion artifacts, and physicians need to select the appropriate reconstruction phase to obtain a diagnostic image. ...
