Diagnostic Radiation Physics Services (DRPS) provides board-certified medical physics and radiation safety consulting to healthcare facilities in Sacramento and throughout the Sacramento metropolitan area, including Roseville, Elk Grove, Folsom, Davis, and the greater Sacramento Valley. DRPS supports hospitals, imaging centers, outpatient departments, and specialty practices that need responsive, credentialed physics coverage without the overhead of in-house physics staff.
Medical Physics Services in Sacramento
DRPS delivers a comprehensive suite of medical physics services to Sacramento-area facilities:
- Equipment Performance Evaluations (EPEs): Annual and acceptance testing for radiographic, fluoroscopic, mammography, CT, and other imaging systems, supporting both regulatory compliance and clinical optimization.
- Radiation Shielding Design and Certification: Structural shielding calculations and design documentation for new construction, renovation, or equipment upgrades, prepared for submission to CDPH.
- Radiation Safety Officer (RSO) Services: Consulting RSO support for facilities with radioactive materials programs or complex radiation safety needs, including license maintenance, staff training, and regulatory correspondence.
- Accreditation Support: Preparation and documentation support for ACR, IAC, RadSite, and Joint Commission accreditation, including phantom imaging, image quality review, and physicist report preparation.
- CT Physics Testing and Optimization: CT acceptance and annual testing per ACR and AAPM guidance, including dose assessment, image quality benchmarking, and protocol review.
- PET/CT and Nuclear Medicine Physics: Acceptance testing, performance characterization, and ongoing QA consultation for PET/CT systems and nuclear medicine departments.
- Quality Assurance Programs: Development and implementation of facility-specific QA programs aligned with applicable standards and accreditation requirements.
California Radiation Regulations
Healthcare facilities in Sacramento are subject to oversight by the California Department of Public Health (CDPH), Radiologic Health Branch. California became an NRC Agreement State in 1962, so CDPH — not the NRC — licenses radioactive materials in the state. X-ray equipment is registered with CDPH under Title 17 of the California Code of Regulations, and California requires certified radiologic technologist and supervisor/operator permits for personnel using X-ray equipment.
Federal and accreditation standards apply alongside state rules. Mammography facilities must meet the federal Mammography Quality Standards Act (MQSA), which requires annual surveys by a qualified medical physicist, and ACR, IAC, Joint Commission, and other accrediting bodies impose their own physics and QA requirements. DRPS tracks current California requirements and these overlapping national standards to keep Sacramento-area clients compliant.
Why Sacramento Facilities Choose DRPS
Board-Certified Expertise. DRPS physicists hold American Board of Radiology (ABR) certification in diagnostic medical physics — the credential that matters for MQSA compliance and ACR accreditation.
Regional Coverage. DRPS serves facilities across the Sacramento metropolitan area, providing consistent coverage for multi-site health systems and imaging networks.
Integrated Compliance and Accreditation Support. Physics surveys, shielding documentation, and accreditation physicist reports are coordinated under a single engagement, reducing administrative burden and eliminating gaps between deliverables.
No In-House Overhead. Facilities gain credentialed physics expertise on a consulting basis, without the cost of a full-time physics hire.
Frequently Asked Questions
Does California require annual medical physics surveys for diagnostic X-ray equipment? Survey frequency depends on equipment type and the standards that apply to your facility. MQSA mandates annual surveys for mammography; California regulations and accreditation standards govern frequency for other modalities. DRPS can review your equipment inventory and establish a compliant survey schedule.
Who regulates radioactive materials licenses in Sacramento? California is an NRC Agreement State (since 1962). CDPH's Radiologic Health Branch issues and oversees radioactive materials licenses; facilities do not apply directly to the NRC. DRPS can assist with license applications, amendments, and ongoing compliance support.
Does DRPS serve facilities outside Sacramento proper? Yes. DRPS provides physics services across the Sacramento metropolitan area, including Roseville, Elk Grove, Folsom, Davis, and the greater Sacramento Valley.
What is required for a new CT scanner installation in California? New CT installations typically require a shielding design before construction, acceptance testing by a qualified medical physicist, state registration, and — for ACR-accredited sites — physicist documentation for the accreditation record. DRPS handles shielding calculations, acceptance testing, and the associated documentation.
Can DRPS serve as our facility's Radiation Safety Officer? Yes. DRPS offers consulting RSO services for facilities that do not need a full-time in-house RSO, including oversight of radioactive materials programs, staff training, audit support, and regulatory correspondence.
