[Intl_DxMedPhys] ACR phantom image submission update

[Gress, Dustin]

Dear colleagues,

I am pleased to share that for all ACR diagnostic accreditation modalities except mammography, the lookback period for phantom submission images has been extended to allow images acquired during the previous annual medical physicist's survey. The following updated paragraph can now be found in the four accreditation support articles pasted below it:


  *   All phantom examinations submitted must have been performed within 14 months of the date on the testing package that was released to the facility. Phantom images from the most recent annual medical physicist's survey may be used, provided they meet all other submission requirements. No images will be accepted for review that predate the testing package date by more than 14 months.

Please note that no change has been made for clinical images, i.e., the lookback period for clinical images remains six months.

Kind regards,
