LED light or Halogenon the X-ray collimator
Let’s look at what X-ray Collimator does.The X-ray generating device is mainly composed of a high voltage generator, a bulb and a columnator. The 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 role of the columator is to limit the range of X-rays emitted from the tube.
The X-ray generating device is mainly composed of a high-voltage generator, a bulb and an X-ray collimator. The X-ray collimator is usually placed under the tube, and the X-ray emitted by the tube is irradiated onto the object through the beam limiter. The role of X-ray collimator is to limit the range of X-rays emitted from the tube. The X-ray collimator generally includes a housing, positioning lights, reflective lenses and opening limit structures. The positioning lights, reflective lenses and opening limit structures are installed in the housing.
The opening limit structure is used to control the size of the X-ray collimator opening, thereby determining the X-ray irradiation range. The function of the positioning lamp is to simulate the X-ray light source and its position of the bulb. After the positioning lamp is energized, the visible light emitted is reflected by the reflective lens, and is emitted from the X-ray collimator opening and irradiates the subject (that is, the patient’s examination site) ), the irradiation position is equivalent to the position where X-rays are irradiated onto the object to be examined, thereby realizing the positioning of the X-ray irradiation area. In the existing X-ray collimator, the positioning lamp uses a halogen lamp. The halogen lamp consumes a lot of power (its power is generally more than 50W, most of them use 150W), and it generates a large amount of heat. After a long period of work, the X-ray collimator shell will be too large. Heat can even cause deformation of some devices.
