Medical Physicist Philadelphia

Board-certified medical physicist services in Philadelphia and the Delaware Valley. DRPS supports imaging facilities across Philadelphia, Montgomery, Bucks, Delaware, and Chester counties with equipment performance evaluations, shielding design, RSO services, and accreditation support.

Diagnostic Radiation Physics Services provides comprehensive medical physics and radiation safety consulting to healthcare facilities throughout Philadelphia and the broader Delaware Valley. Philadelphia is the anchor of one of the densest healthcare markets on the East Coast — a five-county metropolitan area encompassing Philadelphia, Montgomery, Bucks, Delaware, and Chester counties in Pennsylvania, with cross-border connections to Burlington, Camden, and Gloucester counties in southern New Jersey. DRPS board-certified diagnostic medical physicists serve the full range of facilities in this region: independent imaging centers, hospital outpatient departments, academic medical center affiliates, ambulatory surgery centers with fluoroscopy, mammography screening programs, and nuclear medicine and PET/CT departments.

Medical Physics Services in Philadelphia

DRPS provides a complete suite of diagnostic imaging physics and radiation safety services to Philadelphia-area facilities:

  • Equipment Performance Evaluations (EPEs) — Annual and acceptance testing for radiographic, fluoroscopic, mammography, CT, and nuclear medicine equipment, meeting ACR, MQSA, and PA DEP requirements
  • Radiation Shielding Design and Certification — Primary and scatter barrier calculations for new construction and renovation, with post-installation verification surveys and certification letters for PA DEP BRP submission
  • Radiation Safety Officer (RSO) Services — Named RSO coverage for facilities licensed to possess radioactive materials, including radiation safety program administration, personnel dosimetry oversight, and PA DEP BRP liaison
  • Accreditation Support — Physics testing packages and documentation for ACR, IAC, RadSite, and Joint Commission accreditation surveys across all modalities
  • CT Physics Testing — Comprehensive CT scanner performance evaluation, dose index review (CTDIvol, DLP), and optimization support for single- and multi-scanner departments
  • PET/CT and Nuclear Medicine Physics — Equipment performance testing, radiopharmaceutical safety oversight, dose calibrator verification, and radiation safety program support
  • Quality Assurance Programs — Ongoing QA protocol development and implementation across radiography, fluoroscopy, mammography, CT, and nuclear medicine

Pennsylvania Radiation Regulations

All Pennsylvania imaging facilities operate under the regulatory authority of the Pennsylvania Department of Environmental Protection (PA DEP), Bureau of Radiation Protection (BRP). Pennsylvania became an NRC Agreement State on March 31, 2008, and the PA DEP BRP — not the federal NRC — licenses and inspects users of radioactive materials in the Commonwealth. Philadelphia-area nuclear medicine departments and PET/CT facilities hold their radioactive materials licenses through the PA DEP BRP under this Agreement State framework.

Radiation-producing machines (X-ray units, CT scanners, fluoroscopy systems, mammography equipment) must be registered with the PA DEP BRP, and facilities are subject to periodic state inspection. Cross-border facilities in New Jersey operate under a separate Agreement State framework administered by the New Jersey Department of Environmental Protection. Federal standards apply in parallel across all Pennsylvania facilities:

  • MQSA (Mammography Quality Standards Act) — federally enforced for all mammography facilities; requires an annual survey by a qualified medical physicist
  • ACR, IAC, RadSite, and Joint Commission accreditation standards impose additional physics testing and documentation requirements
  • NRC retains jurisdiction over certain materials not covered by the Agreement State transfer

DRPS maintains current knowledge of PA DEP BRP requirements and guides Philadelphia-area facilities through registration, license applications and amendments, inspection readiness, and ongoing compliance recordkeeping.

Why Philadelphia Facilities Choose DRPS

The Delaware Valley imaging market is characterized by high facility density, complex multi-site health system structures, and demanding accreditation environments. Independent imaging centers compete on quality and accreditation credentials, while hospital-affiliated departments face layered Joint Commission and CMS requirements. DRPS is built to serve this market:

  • Board-certified physicists — credentialed by the American Board of Radiology (ABR) in diagnostic medical physics, satisfying ACR and accreditation body physicist qualification requirements
  • Multi-modality, multi-site capability — coordinated EPE programs across distributed outpatient networks spanning Philadelphia and the collar counties
  • Accreditation depth — experience with ACR, IAC, RadSite, and Joint Commission across CT, radiography, fluoroscopy, mammography, ultrasound, MRI, nuclear medicine, and PET/CT
  • Regulatory breadth — PA DEP BRP Agreement State licensing, MQSA compliance, and radioactive materials program management under one consulting relationship
  • Responsive scheduling — flexible site visit scheduling to accommodate high-volume departments and time-sensitive accreditation renewals

Frequently Asked Questions

What modalities does DRPS cover for Philadelphia-area imaging facilities? DRPS covers the full spectrum of diagnostic imaging modalities: general radiography, fluoroscopy, mammography, CT, nuclear medicine, PET/CT, and diagnostic ultrasound physics support. We can serve as the single medical physics vendor across all modalities for a facility or health system.

My Philadelphia imaging center is seeking ACR accreditation. What does DRPS provide? DRPS provides the complete ACR physics testing component, including a written physics survey report structured to ACR specifications, equipment performance testing for the specific modality being accredited, and guidance on image quality phantom scoring and compliance items. We cover CT, radiography, fluoroscopy, mammography, nuclear medicine, and PET/CT accreditation.

Does Pennsylvania's Agreement State status affect how Philadelphia nuclear medicine facilities are licensed? Yes. Pennsylvania is an Agreement State, so nuclear medicine and PET/CT facilities are licensed by the PA DEP BRP, not the federal NRC. DRPS's RSO service includes management of the PA BRP radioactive materials license, including amendments for new radiopharmaceuticals, license renewals, and preparation for BRP inspections.

Can DRPS serve facilities in the Philadelphia suburbs — Montgomery, Bucks, Chester, and Delaware counties? Yes. DRPS serves the entire five-county Delaware Valley area in Pennsylvania, as well as cross-border facilities in southern New Jersey. Geography within the metro area does not limit our coverage.

What is involved in shielding design for a new CT suite or interventional room in Philadelphia? DRPS performs workload-based barrier calculations per NCRP Report No. 147 (CT) or applicable NCRP methodology, prepares a written shielding report with design recommendations, and conducts a post-construction survey to verify installed barrier thickness. A certification letter is provided for PA DEP BRP and building permit purposes.
