Body surface location method and system

Abstract

An embodiment of the invention discloses a body surface location method. The body surface location method includes that a first image collector acquires a test point of the body surface; a first bed size is acquired, to be specific, the first bed size is s horizontal bed size corresponding to an intersection point of the upper surface, of a current bed, and a connecting line, of the first image collector and the test point of the body surface; a second image collector measures the vertical distance from the test point of the body surface to the upper surface of the bed; a second bed size is determined according to the first bed size; the vertical distance and a first inclined angle, to be specific, the second bed size is the horizontal bed size of the test point of the body surface, and the first inclined angle is between the connecting line, of the first image collector and the test point of the body surface, and a straight line, formed by projecting the connecting line to the upper surface of the bed; the test point of the body surface is located by the second bed size. An embodiment of the invention further discloses a body surface location system. By the use of the body surface location method and system, X-ray radiation which is caused by human body surface location and which brings damages to patients is avoided, health of the patients is improved, and X-ray dosage is reduced.

Description

technical field

[0001] The invention relates to the medical field, in particular to a body surface positioning method and system. Background technique

[0002] In the process of clinical treatment, it is often necessary to locate the body surface of the human body. At present, CT scanning is usually used for body surface positioning. CT scanning refers to scanning a layer of a certain thickness of a certain part of the human body with an X-ray beam. The X-rays that pass through this layer are received by the detector, converted into visible light, converted from photoelectric to electrical signals, and then converted by analog / digital. The converter converts it into a digital signal and inputs it to a computer for processing.

[0003] However, as X-rays irradiate the human body, the cells may be inhibited, destroyed or even necrotic, resulting in varying degrees of physiological, pathological and biochemical changes in the body, thus causing harm to the human body, such as ...
