PET/CT & Nuclear Medicine Physics — SPECT, Gamma Camera, and Dose Calibrator Services

What are PET/CT and nuclear medicine physics services?

Full medical-physics support for facilities operating nuclear imaging equipment and radiopharmaceutical programs — equipment performance evaluations, QA programs, ancillary instrument testing, radiation safety support, and regulatory compliance for PET, PET/CT, SPECT, gamma cameras, and planar nuclear medicine.

Services

PET and PET/CT physics

Annual EPEs covering PET spatial resolution, sensitivity, coincidence timing resolution, scatter fraction, and count rate performance per NEMA NU-2 standards, plus CT-component dose (CTDIvol, DLP) and image quality — all in one consolidated report.

SPECT and gamma camera physics

Comprehensive system evaluations covering uniformity, spatial resolution, sensitivity, and multi-window spatial registration. Includes daily, weekly, monthly, and annual QA program development and documentation.

Planar nuclear medicine

Performance testing for planar gamma camera imaging, including field uniformity and spatial resolution assessments.

Dose calibrator testing

Accuracy, linearity, constancy, and geometry testing of dose calibrators to NRC 10 CFR Part 35 and Agreement State requirements.

Well counter testing

Constancy, efficiency, and minimum detectable activity testing for well counters used in wipe testing and patient specimen counting.

Radiopharmaceutical safety

Handling, storage, and administration procedures; spill response protocols; patient-release calculations; and radioactive-waste guidance.

ACR accreditation support

Physics testing and documentation for ACR PET Accreditation Program (PETAP) and ACR Nuclear Medicine Accreditation Program (NMAP) — image-quality review and full submission-package preparation.

Radiation safety support

Named RSO services, occupational dose monitoring, area surveys of hot labs and imaging suites, and shielding adequacy reviews for nuclear medicine facilities.

Regulatory framework

NRC 10 CFR Part 35 (medical use), state radiation-control programs (FL, MD, VA, DC, CA, NV, PA, NY, NJ, DE), ACR PET and nuclear medicine accreditation standards, Joint Commission standards, and applicable FDA radiopharmaceutical requirements.

Service area

DRPS serves PET/CT and nuclear medicine facilities across Florida, Maryland, Virginia, Washington DC, California, Nevada, Pennsylvania, New York, New Jersey, and Delaware.

FAQ

How often do PET/CT systems need physics testing?

Annual comprehensive evaluations, plus testing after new system installation, major component repairs, or accreditation cycles.

What's in a PET/CT evaluation?

Both PET and CT components — spatial resolution, sensitivity, count rate performance, image quality, and dose — in a single consolidated report.

Do you test SPECT and gamma camera systems?

Yes — uniformity, spatial resolution, sensitivity, and multi-window spatial registration, with QA program documentation.

Do you test dose calibrators and well counters?

Yes — dose calibrator accuracy, linearity, constancy, and geometry; well counter constancy, efficiency, and minimum detectable activity.

Can you support radiopharmaceutical therapy programs?

Yes — shielding, license amendments, patient-release calculations, and first-case physics coverage.

What QA is required for nuclear medicine?

Daily, weekly, monthly, and annual requirements depend on the specific equipment and regulatory program. We build QA programs sized to your license and accreditation.
