Embodiment Construction

[0012] The specific steps of the method of the present invention are as follows: (1) Obtain medical raw data through multicolor radiation source CT. (2) Three-dimensional surface reconstruction. (3) Obtain the value difference of each point near the surface under different energy CT. (4) Map the differences into color information. (5) Give color to the three-dimensional surface and display it. The technical solution of the present invention will be further described in detail below in conjunction with a specific embodiment.

[0013] This embodiment uses the inner wall surface of the human colon as a sample for color mapping. The realization process of whole invention is as follows:

[0014] 1. Use 100kV, 120kV and 140kV radioactive sources to perform CT scans on the lower abdomen of the human body, and obtain three groups of CT tomographic image data.

Abstract

The multiple energy radioactive source CT imaging method for realizing color organ surface mapping belongs to the field of image processing technology. The method includes first multiple energy radioactive source CT imaging to obtain original image and 3D reconstruction of the organ to be observed and diagnosed, the subsequent converting the difference of energy values obtained with the multiple energy radioactive source CT imaging near the organ into different colors, and the final endowing the colors to the surface of the organ before displaying. The present invention distinguishes different tissues based on their difference in absorbing energy rays, like that different matters absorb light of different energy to show different colors. The present invention makes it possible to simulate relatively realistic colors on the surface of organ by means of neural network method for doctor to diagnose conveniently.

Description

technical field [0001] The invention relates to a method in the technical field of image processing, in particular to a method for realizing color mapping of organ surfaces by using multi-energy radiation source CT imaging. technical background [0002] At present, the three-dimensional visual reconstruction of various organs in the body mainly uses ordinary single-source CT or MRI to image the organs to be observed, and then uses image processing, three-dimensional Observation and diagnosis of organs from different angles. Ordinary CT and MRI imaging, the data obtained are only grayscale data, and there is no color information. Since the human eye has a limited ability to distinguish between grayscale levels and a stronger ability to distinguish different colors, various color mapping methods define the relationship between different pixel values ​​to different color values. The general color mapping method is only a simple correspondence from the original gray value to t...
