The TO XR21 phantom was designed to allow the user to check image quality in accordance with the NEMA XR21 standard. This phantom is manufactured from PMMA and enables various QA checks.
The modular stacking design of the plates allows variation of phantom thickness in steps of 25mm, up to a total of 300mm, simulating a range of patient sizes.
TO XR21 measures:
- Spatial resolution
- Contrast (iodine) resolution
- Radiation field size
- Beam alignment
- Working thickness range
- X-ray to light field alignment
- Dose (dose meter not supplied)
Conforms to standards:
- NEMA XR21 Standard
