To test the standard of X ray collimator?

At present, there are various x ray collimators on the market, and each company’s collimator in spectrometer will be more or less different. So what are the criteria for these manufacturers to manufacture collimator in spectrometer? Today I will tell you about the industry standard for a lower limit beamer.

In the industry standard YY0007~0009-90 on the technical standard of 200~500mA medical diagnostic X-ray machine, the performance requirements of collimator in spectrometer are explained in Article 4.19:
1. Collimator in spectrometer should be light, flexible, reliable, and can adjust the rectangular field of any size;
2. When the gastrointestinal examination photographic device is pulled farthest from the bed surface, when the collimator in spectrometer is kept to a minimum, the irradiation field on the fluorescent screen should be no more than 20mmx20mm;
3. The deviation of the X-ray field center from the center of the light field and the deviation of their respective edges should be within 2% of the X-ray tube focus to the image surface distance.
