CT (computed tomography) positioning system implemented by using visible light and infrared light and CT positioning method

Abstract

The invention discloses a CT (computed tomography) positioning system implemented by using visible light and infrared light and a CT positioning method. The CT positioning system comprises multiple visible light and infrared cameras and a computer system, the computer system comprises a three-dimensional reconstruction module, a human model database, a matching and positioning output module and an attribute input module; the three-dimensional reconstruction model reconstructs outer human contour models according to image information acquired by the visible light and infrared cameras; the human model databases stores multiple default three-dimensional human models; the attribute input module inputs attribute information of the outer human contour models; the matching and positioning output determines the three-dimensional human models matched with the attribute information from the human model database according to the attribute information, matches the outer human contour models with the three-dimensional human models matched with the attribute information and positions positional information of specific parts of human body. With the system and method, X-ray scanning is not needed, and damage caused to the human body by X-ray can be reduced.

Description

technical field [0001] The invention relates to a CT positioning system and method, in particular to a CT positioning system and method realized by using visible light and infrared light. Background technique [0002] CT machine is a commonly used medical equipment. Before CT scanning, it is generally necessary to scan the patient in advance to locate the patient's part information, that is, use X-rays to scan the entire human body or a certain range of the human body, and determine the body specificity according to the scanning results. Afterwards, regular scans can be performed on specific parts of the body, or enhanced scans can be performed with contrast agents. The plain film scanning process does not need to use contrast agents, and the radiation dose is relatively small. Even so, X-rays will have a certain impact on the human body. Moreover, for accurate positioning, it is sometimes necessary to perform plain film scanning of the human body from two directions to obta...
