Light beam forming device, X-ray machine with light beam forming device and light beam forming device control method

Abstract

The invention provides a light beam forming device, an X-ray machine with the light beam forming device and a light beam forming device control method. The light beam forming device comprises a machine frame (10), slide doors, driving mechanisms, position detection mechanisms and a control device, wherein the slide doors comprise a first slide door (20a) and a second slide door (20b), the first slide door (20a) and the second slide door (20b) are glidingly arranged on the machine frame (10) in the same plane and have first positions and second positions, the first positions relatively go far away for opening the slide doors, the second positions relatively approach to each other for closing the slide doors, the driving mechanisms comprise a first driving mechanism (30a) in driving connection with the first slide door (20a) and a second driving mechanism (30b) in driving connection with the second slide door (20b), the position detection mechanisms comprise a first position detection mechanism used for detecting the position of the first slide door (20a) and a second position detection mechanism used for detecting the position of the second slide door (20b), and the control device is respectively connected with the driving mechanisms and the position detection mechanisms. The light beam forming device has the advantage that the X-ray range can be accurately controlled to be around radiated objects.

Description

technical field [0001] The present invention relates to the technical field of medical equipment, in particular to a beam beamer, an X-ray machine with the same, and a beam beamer control method. Background technique [0002] The X-ray machine is a commonly used device for perspective and filming in the medical field. The X-rays emitted by the X-ray tube are projected onto the object to be illuminated to complete the perspective process. Because X-rays are harmful to the human body, in order to control and reduce the radiation range of X-rays and minimize the damage to the human body, a beam device is generally used to limit the radiation range of X-rays. [0003] The beam light device is also called "wire shroud", "shrinker" or "beam limiter". It is generally installed at the window of the X-ray tube sleeve to block unnecessary primary X-rays during X-ray inspection. [0004] The main functions of the beam light device can be summarized as follows: [0005] 1. Limit the r...

Problems solved by technology

The disadvantage of the double-door linkage structure is that if the object 70' to be irradiated deviates from the vertical centerline of the window 80' of the X-ray tube, the first sliding door 20a' and the second sliding door 20b' need to use the object 70' to be irradiated. The actual position is to open to both sides, resulting in an increase in the opening between the first sliding door 20a' and the second sliding door 20b', which actually increases the range of X-ray irradiation, thereby weakening the beam control.
