RaySafe Pro-CT 500

RaySafe Pro-CT 500 is a CT quality assurance phantom designed for routine quality control, constancy testing, and acceptance testing in diagnostic CT systems.

It supports key image quality parameters described in IEC 61223-3-5 and widely referenced in AAPM reports for CT quality assurance, including HU accuracy, uniformity, noise, spatial resolution, and slice thickness.
Medical physics departments use Pro-CT 500 for regular QA workflows and trend analysis.
This phantom consists of several test modules placed inside a cylindrical container that can be mounted either directly on a holder of the CT table or on an adjustable stand. It allows accurate alignment for measurements on and off the table. Markings on the phantom and levelling aids provide further facilitation of the positioning process.

Can be used for following tests:

• Geometric distortions
• Mean deviation of the HU value
• Noise level/uniformity
• Artifacts
• MTF
• SSP, LSF, PSF
• CNR
• High-contrast resolution
• Z-dimension spatial resolution
• Low-contrast resolution
• Slice profile/slice thickness
• Isocenter compliance
• Linearity
