What is the collimator used for

The collimator is a machine used to control the X-ray output irradiation path and control the irradiation dose, and it is usually used with a tube. The collimator is divided into electric collimator, manual collimator, and automatic collimator. Generally, if it is used on a portable machine, the manual collimator is selected, and the electric collimator is generally used with the gastrointestinal machine. In addition, many collimators are also equipped with tape measures to facilitate doctors to measure the distance from the collimator to the patient.
