A three-dimensional positioning method

Abstract

The invention provides a three-dimensional positioning method. According to the method, a positioning point is determined in a positioning area, a three-dimensional coordinate axis is set, a body surface marking point which is required to reach the positioning point is drawn, and then positioning is finished. The method has the advantages that the body surface marking point can be accurately found, and the positioning point can be found accurately by using the body surface marking point as a reference point.

Description

technical field

[0001] The invention relates to a three-dimensional positioning method. Background technique

[0002] At present, the C-arm X-ray machine we use cannot accurately locate the treatment point on the body surface that enters the positioning point when projecting. for accurate positioning. Contents of the invention

[0003] The present invention proposes a positioning method, which can effectively overcome the deficiencies in the prior art. The method can accurately locate the body surface marking points, and then use the body surface marking points as reference points to accurately locate the positioning points .

[0004] The technical scheme of the present invention is achieved in that a kind of three-dimensional positioning method comprises the following steps:

[0005] (1) Determine the positioning point in the positioning area;

[0006] (2) Set the three-dimensional coordinate axis: according to the anatomical orientation of the human body, we set the ...
