Embodiment Construction
[0044] 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.
[0045]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 the ball tube and the detector to scan, and the computer device is also used to receive the 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 ape...

The present application relates to a heart image reconstruction method, device and computer equipment. The method includes: using multiple preview images as input, obtaining a chest cavity contour image according to the multiple preview images and maximum density projection; calculating and obtaining the boundary position of the chest cavity contour image according to the chest cavity contour image; according to the chest cavity contour image The reconstruction center is obtained by calculating the boundary position of , and the heart image is obtained by performing multi-phase reconstruction according to the reconstruction center and the preset reconstruction field of view. By first selecting the heart position and performing multi-phase image reconstruction according to the heart position, the amount of input data is reduced, the time for data input is further reduced, and the calculation efficiency is improved.
Description
technical field [0001] The present application relates to the technical field of image reconstruction, in particular to a heart image reconstruction method, device and computer equipment. Background technique [0002] With the development of medical equipment technology, the technology of using CT scanners to detect patient parts is becoming more and more mature. When a CT scanner is used, the CT scanner acquires data of multiple phases, and performs image reconstruction based on the data of multiple phases to obtain an image of a diseased part. During cardiac CT scanning, due to the movement of the heart, it is necessary to select the optimal phase data for image reconstruction during image reconstruction. [0003] In the current traditional technology, according to the data of multiple phases, image reconstruction is performed on the data of each phase respectively to obtain reconstructed images of all phases, and the optimal phase reconstructed image is obtained by compa...
