Medical Display Evaluations
Diagnostic accuracy depends on consistent display performance across the entire imaging chain. We evaluate medical displays used for interpretation, acquisition review, and clinical decision-making.
We evaluate:
- Diagnostic radiologist displays for mammography and non-mammography interpretation
- Modality acquisition displays at the scanner
- Clinical specialist displays used in cardiology, orthopedic, dental, and procedural settings
- Displays used for clinical decision-making in PACS, enterprise viewers, and EHR environments
- Remote and off-site diagnostic interpretation workstations, including mammography workstations where applicable
- Conformance with AAPM TG-270, DICOM Grayscale Standard Display Function (GSDF), and ACR display performance standards
Our Chief Medical Physicist, Dr. Mosa Alhamami, is a voting member and co-author of the AAPM Medical Physics Practice Guideline MPPG 17.a: Quality Management for Mammography Review Workstation Displays, contributing directly to the national professional standard governing how mammography review workstation displays are evaluated and maintained.
Acceptance Testing and Equipment QC
New equipment installations, replacements, major upgrades, and detector changes should be independently evaluated before routine clinical use. Acceptance testing verifies performance specifications, establishes baseline image quality and dose metrics, and identifies deficiencies before the facility accepts the equipment.
We provide acceptance testing and equipment QC support across:
- CT
- MRI
- Mammography and tomosynthesis
- Fluoroscopy and interventional systems
- General radiography and mobile imaging
- Dental and CBCT systems
- Chiropractic and veterinary radiographic systems
- Ultrasound
- Nuclear medicine, SPECT, PET, and hybrid systems
Independent acceptance testing helps facilities avoid accepting equipment that does not meet specification and establishes a defensible baseline for future performance comparisons.
Shielding Design and Radiation Protection Surveys
We provide radiation shielding services for new construction, renovations, relocations, room conversions, and equipment replacements.
Our shielding services include:
- Pre-construction shielding calculations meeting NCRP Report 147 and applicable state requirements
- Shielding designs for CT, fluoroscopy, mammography, dental, chiropractic, veterinary, nuclear medicine, and theranostics spaces
- Radiation safety evaluations for dental, chiropractic, and veterinary imaging clinics
- Preparation of state radiation control program submission materials
- Post-construction shielding integrity surveys
- Barrier evaluations for adjacent occupied spaces
- Retrofit shielding evaluations when imaging rooms are relocated, repurposed, or upgraded
Facility Planning and Pre-Construction Consulting
Early physicist involvement in imaging facility planning can prevent expensive redesign, shielding changes, workflow inefficiencies, and regulatory delays.
We support:
- Equipment selection and technical specification review
- Room layout, workflow, and patient-access planning
- Shielding and occupancy review during design
- Coordination with architects, contractors, vendors, and facility leadership
- Regulatory pathway planning and submission timing
