We perform magnification using only the 18 X 24 cm image receptor. Do we have to show that all our other image receptor sizes also meet the magnification requirements?
No. However, the facility is reminded that for each image receptor size used clinically for magnification, the system must meet the following three requirements:
- 900.12(b)(4)(iii) - system capable of operating with the grid removed from between the source and the image receptor
- 900.12(b)(6)(ii) - system provides at least one magnification from the range of 1.4 to 2.0
- 900.12(e)(5)(iii) - system resolution
If the facility performs magnification using multiple sizes of image receptors, then it must meet the requirements with each size receptor used for magnification.
