How to use collimator with X-ray machine

The collimator is also called the beam beam device. It is one of the important components of the X-ray machine. Its main function is to adjust the X-ray projection range. Collimators are mainly divided into manual, electric and automatic.
The collimator is usually connected with the tube, and its function is to position and use it during positioning, simulating the radiation area of the X-ray machine, which can reduce the radiation dose of the patient and improve the image quality. In addition, it can indicate the projection center and the size of the projected field of view. Therefore, the collimator is an indispensable auxiliary device for X-ray machine irradiation and protection.
The manual collimator realizes the opening and closing of the collimator covering the lead leaves by manually adjusting the knob or pull rod on the collimator. The automatic collimator does not need to be operated manually or other physical keys, and the lead leaf can be automatically adjusted by setting parameters. This kind of beam device adopts the CAN communication protocol, and is mainly used in C-arm X-ray machines with dynamic flat panel detectors. Compared with ordinary collimators, the price of automatic collimators is relatively much higher.
