Body surface positioning method and device

Abstract

The embodiment of the present invention discloses a method for locating the body surface. The method includes: before the CT diagnostic scan, use the first image collector to collect the frontal image of the scanned human body, and determine the measured body surface of the scanned human body according to the frontal image. point, and obtain the projection angle of the line connecting the body surface measured point and the first image collector on the scanning bed; use the second image collector to collect the side image of the scanned human body, and use the side image to obtain the measured body surface The vertical distance between the point and the scanning bed, and obtain the current bed height of the scanning bed, the initial bed height of the scanning bed, and the horizontal bed code corresponding to the initial position of the measured point on the body surface; Scan the horizontal bed code on the bed to realize the positioning of the measured points on the body surface. The embodiment of the present invention also provides a body surface positioning device. The invention improves the health level of patients and saves X-ray dose.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201410582659.2 and the title of the invention "a body surface positioning method and system" submitted to the China Patent Office on October 27, 2014, the entire contents of which are incorporated in this application by reference middle. technical field [0002] The invention relates to the medical field, in particular to a body surface positioning method and device. Background technique [0003] In the process of clinical CT scanning, it is usually necessary to perform X-ray plain film scanning of the scanned human body for positioning. As X-rays irradiate the human body, cells may be inhibited, destroyed or even necrotic, which may cause harm to the scanned human body, such as hair loss, skin burns, visual impairment, leukemia, etc. Therefore, how to reduce the damage to the human body caused by X-ray irradiation during CT scanning is a problem that needs to be studie...
