Halogen or LED light on the X-ray collimator

The X-ray collimator device is mainly composed of a high voltage generator, a bulb and a columnator. The X-ray collimator columator is usually placed under the bulb, and the X-rays emitted by the bulb are irradiated onto the object to be inspected by the beam limiter. The X-ray collimator role of the is to limit the range of X-rays emitted from the tube. The columator generally includes a housing, a positioning lamp, a reflective lens, and an opening stop structure, and the positioning lamp, the reflecting lens, and the opening limiting structure are mounted in the housing.
The X-ray collimator opening limit structure is used to control the size of the columnar opening to determine the range of X-ray illumination. The function of the positioning lamp is to simulate the X-ray source of the bulb and its position. After the positioning lamp is energized, the emitted visible light is reflected by the reflecting lens, and is emitted from the columnar opening and irradiated to the object to be inspected (ie, the part where the patient is inspected). The position of the irradiation corresponds to the position where the X-ray is irradiated onto the object to be inspected, thereby realizing the positioning of the X-ray irradiation region.
