Problems solved by technology

Although this method has high computational efficiency, the large distance between the sampling points in the detector row direction will lead to the expansion of the reconstruction layer thickness, which will seriously degrade the resolution in the Z-axis direction.

Abstract

The invention provides an image reconstruction method and device of a medical scanning image. The method includes the following steps: receiving scanning data from medical image equipment; determining projection values of a pair of conjugate rays of each voxel; and performing multi-order interpolation on the projection values of the pair of conjugate rays in a row direction of a detector of the medical scanning image. The reconstruction method of the medical scanning image can improve the longitudinal resolution of a scanned object.

Description

technical field [0001] The present invention mainly relates to medical scanning image processing, in particular to a method and device for reconstructing medical scanning images. Background technique [0002] Computed Tomography (CT) technology is based on the fact that different substances have different attenuation properties for rays. It uses radioactivity to irradiate the measured object from all directions, measures the intensity of the rays passing through the object, and calculates it through a certain reconstruction algorithm. The linear attenuation coefficient of the material at each point inside the object for the rays, so as to obtain the tomographic image of the measured object. Radiological diagnostic technology. [0003] The CT image data obtained by the CT scan is stored after image reconstruction for viewing by an operator. When evaluating the reconstructed image quality of high-resolution CT imaging, the slice sensitivity profile (Slice Sensitivity Profile,...
