A facility's x-ray unit has two magnification attachments that provide a magnification of 1.5 or 2.2, depending on which attachment is used. Other values specified in the regulation cannot be achieved using that unit.
Must a facility purchase new attachments to cover the range, and does it mean that magnification at the 2.2 level must be discontinued?
No. The requirement is that the x-ray unit provide "at least one magnification value" in the range of 1.4 to 2.0 (in this case, the 1.5 meets the requirement). The regulation does not prohibit the presence or use of additional magnification settings.
