The quality control testing system for medical X-ray machines is designed to ensure the performance of equipment in the hospital's radiology department, improve image quality, and reduce the radiation dose to the subjects. In order to comply with the implementation of Ministerial Order No. 34 issued by the Ministry of Health, QC testing boxes have been developed and produced. These two sets of testing tools respectively perform acceptance inspection and stability inspection on X-ray machines. Their outstanding advantages are: easy to operate, fast, and versatile. It is an indispensable testing tool for protection departments and maintenance personnel, which enhances the new content of radiation protection monitoring work and can also serve as a stability test for hospital radiology departments.
The FWJ detection device box includes: 1. Wire harness center verticality detection cylinder; 2. Filter grid straight detection board; 3. Light field/irradiation field consistency detection board; 4. Film/intensifying screen contact detection board; 5. Low contrast resolution detection board; 6. High contrast resolution detection board; 7. X-ray tube focus detection cylinder; 8. Half value layer filter plate; 9. Line to card (0.6-5.0p/mm); 10. Photometer; 11. QC operation USB drive; 12. Operation manual; 13. Packaging box;
The FWJ testing device measures fifteen indicators (some items need to be matched with the diagnostic dosimeter): 1. The perpendicularity between the X-ray beam and the image receiver; 2. Align the center of the filter grid; 3. Film screen contact integrity; 4. Low contrast resolution; 5. High contrast resolution; 6. Focal spot size; 7. X-ray radiation dose; 8. Half value layer; 9. Repeatability of output quantity; 10. The linearity of mAs; 11. Line quality; 12. Automatic exposure control; 13. Consistency between light field and irradiation field;
