What is CT physics testing?
CT physics testing is the annual (and as-needed) evaluation of a CT scanner's radiation dose, image quality, equipment performance, and safety. Regular testing keeps scanners operating within spec and keeps your facility inspection- and accreditation-ready.
What we measure
Radiation dose
CTDIvol, DLP, patient dose estimates, organ-dose assessments, and concrete recommendations for dose reduction.
Image quality
Spatial and contrast resolution, noise, uniformity, and artifact assessment.
Equipment performance
Table movement accuracy, gantry tilt, laser alignment, collimation, and tube-current modulation behavior.
Safety
Interlocks, AEC performance, collimation accuracy, and patient-positioning checks.
Services
Annual performance evaluation
A complete ACR/state-compliant report covering dose, IQ, equipment, and safety in one visit.
Dose optimization
Protocol-by-protocol review with phantom validation and clinical image sign-off — reduce dose without losing diagnostic quality.
Image quality optimization
Reconstruction tuning, contrast timing, and artifact reduction for challenging protocols.
ACR CT accreditation support
ACR-CTAP testing, image-quality reviews, and full submission-package preparation.
Ongoing QA
Monthly QA testing, dose monitoring, and protocol review — everything the regulators expect between annual visits.
Regulatory framework
Testing is performed to state radiation-control requirements (FL, MD, VA, CA, NV), ACR-CTAP, Joint Commission medical-physics standards, and applicable FDA equipment requirements.
FAQ
How often does a CT need physics testing?
Annually for the comprehensive evaluation, plus testing after major service, tube replacement, or significant protocol changes.
What's in a standard CT evaluation?
Dose measurements, image-quality phantom testing, equipment-performance checks, safety verification, and a compliance report suitable for state and ACR submission.
Can you optimize our protocols?
Yes — dose analysis, optimized protocol drafts, phantom validation, and clinical review.
Do you handle ACR CT accreditation?
End to end — physics testing, image QC review, documentation, and submission coordination.
What happens if a scanner fails a test?
You get a specific remediation plan, and we coordinate with your service vendor until the system passes.
