Extension Rings

Extension Rings for Standard Phantoms

Simulate larger patient anatomies and obesity scenarios
Compatible with multiple QRM standard phantoms
Available in tissue- and fat-equivalent materials
Optional dosimetry version for radiation dose measurements

Extension Rings help evaluate the impact of increased patient size and attenuation on image quality in CT and other 3D imaging modalities. Designed for use with (semi-)anthropomorphic phantoms, they support realistic testing conditions for a wide range of quality assurance applications.

Available in sizes M, L and XL, the rings can be manufactured from tissue- and fat-equivalent materials. Additional materials, e.g. water-equivalent materials with specified CT numbers (HU), are available upon request to support specific testing requirements.

For dosimetry applications, an optional version with pre-drilled measurement holes is available for radiation dose measurements.

Need Extension Rings for a different phantom or application? Customized configurations are available upon request.
