What is an x-ray collimator used for?

The   x ray collimator, as the name implies, plays the role of shrinking the beam. The actual function is to first turn on the light on the collimator and adjust the knobs in the X and Y directions of the collimator, so that the light of the collimator shines on the film box of your machine, so that the size of the light field is just the size of the film. Agree, and then you can shoot. Because the machine must adjust the X-ray field and the light field to a minimum deviation before leaving the factory, this light field plays the role of simulating the invisible X-ray field.
The collimator is an accessory part used for X-ray inspection equipment. It is mainly used for positioning during positioning. It simulates the radiation area of ​​X-rays, which can reduce the radiation dose of patients and enhance image quality. Weifang NEWHEEK  Electronics specializes in the production of beamers. , there are two kinds of manual and automatic.
Some manual beam stoppers are also known as simple beam limiters. There are two types of simple beam limiters: shading plate type and shading cylinder type. The shading plate type is to install a lead plate with a square or circular hole of a certain size on the X-tube sleeve window, and the opening of the lead plate is symmetric with the center of the X-ray. When performing projection, an irradiation field suitable for the size of the hole can be obtained at a certain distance. Generally, an X-ray machine is equipped with multiple shading plates with different apertures, and the size of the irradiation field at the corresponding distance is indicated on it for selection. The shape of the shading tube beam limiter is a conical metal tube, and some are also lined with thin lead sheets to increase the protective effect. When projecting, it mainly depends on the blocking and absorption of X-rays by the cylinder wall to limit the irradiation field. Therefore, the size of the irradiation field can be determined by the length and diameter of the shading cylinder, and the irradiation field is generally circular.
