Multi-planar reconstruction imaging method for medical images

Abstract

The invention discloses a multi-planar reconstruction imaging method for medical images, comprising the following steps: (a) scanning an inspection area of a target to be imaged, and acquiring the three-dimensional image sequence of the inspection area, wherein the three-dimensional image sequence is composed of a group of two-dimensional image sequences; (b) selecting an effective area image sequence from the two-dimensional image sequences, and determining the three-dimensional center of the effective area image sequence; and (c) taking the three-dimensional center of the effective area image sequence as a reconstruction center to perform multi-planar reconstruction imaging on the inspection area. According to the multi-planar reconstruction imaging method for medical images provided by the invention, the three-dimensional image sequence of the inspection area is screened to select the effective area image sequence and abandon noise area images, and then, the three-dimensional center of the effective area image sequence is determined and taken as the reconstruction center of multi-planar reconstruction imaging, thus improving the accuracy of positioning and reconstruction imaging.

Description

technical field [0001] The invention relates to a medical image imaging method, in particular to a medical image multi-plane reconstruction imaging method. Background technique [0002] The image of multi-planar reconstruction imaging technology (MPR, Multi-planer Reformation) is generated after data processing based on the initial volume data (volumetric data) collected by medical imaging equipment. A general MPR image processing procedure is to obtain coordinates in view space, convert the coordinates to volume space, use arbitrary forms of interpolation, resample the volume data, and generate new MPR data values ​​for discrete view space coordinates. MPR slices (two-dimensional image sequences) are formed by performing the process on multiple (x, y) coordinates at a fixed z value. When the above processing is repeatedly performed for a plurality of values ​​of z, a plurality of MPR slices are determined, and these slices are projected to form an MPR three-dimensional ima...

Problems solved by technology

[0003] In the above-mentioned multi-plane reconstruction imaging process for 3D objects, a key point is to determine the reconstruction center of multi-plane imaging, and generate MPR slices in three orthogonal directions based on the reconstruction center. However, there is no accurate reconstruction center at present. effective method

If the reconstruction center is not at the exact center of the 3D target that needs to be imaged, it will have a great impact on the MPR image, because the MPR image probably only reflects the local information of the target
