QSI new standard

For those of you that had QSI accreditation on the new standard, I am hoping you might be able to assist with a query

This is one of the requirements that requires evidence. Could anyone share any ideas of what I could provide?

"Process to ensure that measurement parameters are calibrated and checked, and uncertainty measurement considered” – this requirement is linked to XR-509

We are in the process of putting some evidence together for this - our starting point was reviewing each quantitative measurement that is taken from radiology images and working out what we can say about them.

Has anyone complied with this requirement yet?
