What is a collimator in radiology

The collimator belongs to an optical element used for input and output of the optical fiber communication optical device, and its structure is very simple – the divergent light from the optical fiber becomes parallel light (Gaussian beam) through a similar convex lens in the front.
First of all, we can divide X-ray collimators into two categories in terms of operation methods: electric X-ray collimators and manual X-ray collimators. Different operation methods are suitable for different rays. Motorized X-ray collimators are mainly used for dynamic viewing angles, such as remote control of gastrointestinal machines, without near-stage adjustment, and can be remotely controlled according to the system or other operating methods. The manual X-ray collimator is more suitable for filming, and the beam limiter covered with lead leaves can be opened and closed by manually adjusting the knob or lever on the beam limiter. Its internal structure is also equipped with an illuminated area indicator system.
In a word, the collimator is an accessory part used for X-ray inspection equipment.
