With the development of the X ray machine, the x ray collimator has evolved from simple to complex in structure, with functions ranging from single to multi-purpose. Types are divided into simple collimating device, manual collimating device, electric collimating device and fully automatic collimating device.
Let me tell you what is the difference between a simple collimating device and a manual collimating device:
The simple collimating device has two types of occlusion type and occlusion type. The occlusion type is a lead plate with a certain size or a circular hole in the X-tube window. The opening of the lead plate is centered on the X-ray center. When the projection is performed, an irradiation field suitable for the size of the hole can be obtained at a certain distance. Generally, an X ray machine is equipped with a plurality of occlusion panels of different apertures, and the size of the illumination field of the corresponding distance is indicated above for selection.
Manual x ray collimator is mostly used in radiography. This collimator occlusion line is opened and closed by manually adjusting the knob or pull rod on the collimator. The internal structure of the X ray collimator is provided with an illumination field indicating system in addition to the foregoing.
Newheek has three manual collimating devices, NK102, NK103 and NK202.
