MRI quality control from the physicist who wrote the book.
For more than 30 years, Dr. Moriel NessAiver has kept MRI scanners performing at their best — and made MRI physics make sense to the people who run them. ACR accreditation, daily QA, and fMRI stability testing, all handled simply.
Not all physicists are created equal
Two services. One specialty.
Clinical MRI QC
Easy ACR accreditation.
- Daily QA from a 5-minute scan — we analyze the results and alert you within half an hour.
- Yearly full-system testing that checks every channel of every RF coil.
- Over 99% first-attempt ACR pass rate across 1,000+ submissions. If a submission fails, we pay the resubmission fee.
Functional MRI QC
Stable machines. Accurate results.
- The first complete fMRI QA package: 40+ stability metrics for every slice and time point.
- Proprietary detection of problems in modern multiband protocols.
- Instant anomaly alerts, with longitudinal tracking against benchmarks for similar scanners.
Results available online within half an hour.
