Body surface location method and device

Abstract

The embodiment of the invention discloses a body surface location method. The method comprises steps: before CT diagnostic scanning, a first image collector is used for collecting a front image of a scanned human body, a body surface detected point of the scanned human body is determined according to the front image, and a projection included angle of a connection line between the body surface detected point and the first image collector on a scanning bed is acquired; a second image collector is used for collecting a side image of the scanned human body, the side image is used to obtain a vertical distance between the body surface detected point and the scanning bed, and the current height of the scanning bed, the initial height of the scanning bed and a horizontal bed code of the body surface detected point corresponding to the initial position are acquired; and the horizontal bed code of the body surface detected point on the scanning bed is calculated and obtained through acquiring the above parameters, and body surface detected point location is realized. The embodiment of the invention also provides a body surface location device. The healthy level of a patient is improved, and the X ray dose is saved.

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...
