Intersocietal Accreditation Commission
IAC accreditation medical physicist services. Annual CT physicist surveys and MRI and nuclear/PET physics testing to support Intersocietal Accreditation Commission (IAC) accreditation for imaging facilities.
Requirements
- CT: an annual survey by a site-appointed medical physicist or qualified expert covering image quality, representative patient dose and oversight of the quality improvement program
- MRI: IAC's MRI standards include a Medical Physicist standard (specified board certification or state license, continuing education that includes MRI safety, approval of any assistants' work and signature on the final report); annual QC assessments may be done by the service engineer as part of preventive maintenance or by the qualified medical physicist
- Nuclear/PET: preventive maintenance every six months plus the facility's QC program; IAC's nuclear/PET standards have no medical physicist standard
- PET/CT and SPECT/CT: the CT component falls under the IAC CT standards, so the annual CT physicist survey applies
- For CT, the physicist survey report is submitted with the application (survey completed within the past 12 months)
Benefits
- IAC is one of the accrediting organizations CMS recognizes for advanced diagnostic imaging under MIPPA
- Confidential peer review of your CT, MRI or nuclear/PET program
- A physicist survey report that documents CT image quality and patient dose
Accreditation Process
- Submit the online application with supporting documentation and case studies
- Confidential peer review; staff check the application for completeness and the IAC Division Board makes the accreditation decision
- On-site visits and audits are random or required in specific cases, not routine
Maintenance Requirements
- Accreditation is granted for a maximum of three years
- No annual interim report is required, but changes must be reported to IAC within 30 days
- The annual CT physicist survey continues between accreditation cycles
What IAC accredits
IAC (the Intersocietal Accreditation Commission) accredits many program types, including vascular testing, echocardiography, nuclear/PET, MRI and CT. The programs where diagnostic medical physics matters most are CT, MRI and nuclear/PET.
The physicist's role differs by program
IAC's CT standards require an annual survey by a site-appointed medical physicist or qualified expert, covering image quality evaluation, a representative patient dose assessment and oversight of the quality improvement program. IAC's MRI standards include a Medical Physicist standard covering qualifications, approval of assistants' work and signing the final report, while annual QC assessments may be performed by a service engineer as part of preventive maintenance or by the qualified medical physicist. IAC's nuclear/PET standards have no medical physicist standard and rely on preventive maintenance every six months plus the facility's QC records. Your state, your other accreditors or your payers may still require annual physics surveys, so confirm the requirements that apply to your facility.
How DRPS supports IAC accreditation
DRPS medical physicists perform the annual CT survey and write the report submitted with the application, and can provide MRI and nuclear medicine physics testing that strengthens the QC records reviewers see. See our CT physics testing, MRI physics testing and PET/CT and nuclear medicine physics services.
