- Laboratory commissioning support for new or renovated nuclear medicine facilities
- Patient and staff dose assessments
- Radiation safety audits and compliance support
- Shielding, room-design, and workflow review for nuclear medicine and theranostics programs
Medical Display Evaluations
Diagnostic accuracy depends on consistent display performance across the 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 applicable display quality standards and DICOM Grayscale Standard Display Function (GSDF) expectations
Acceptance Testing and Equipment Quality Control
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 for diagnostic X-ray, CT, fluoroscopy, mammography, dental, chiropractic, veterinary, nuclear medicine, and theranostics spaces
