Catphan® accessories allow you to extend the capabilities of your Catphan® phantom system to simulate a wide variety of imaging conditions and to provide CDRH compliant dose measurement phantoms.


Annuli

Catphan annuli are cast from uniformity material. Annuli are available in a variety of round and oval sizes and mimic the attenuation of patients and their effect on image quality. All annuli are designed to be slipped over 20cm OD Catphan phantoms.

Dose Phantoms

The Dose Phantoms are manufactured to comply with the US government’s Center for Device and Regulatory Health (CDRH) dose phantom specifications. The specifications outline two different sized phantoms, a 16cm diameter phantom for head dose evaluations and a 32cm diameter phantom for body dose evaluation.

CTP553 16cm Head Dose Phantom: The 16cm Dose Phantom is constructed out of acrylic. 13mm (1/2”) holes are bored into the phantom providing cavities for any appropriately sized CT dose probes. The phantom is supplied with 4 blank acrylic rods to be placed in the holes not used for the dose measurement. For ease of use,  a case mount has been added to the phantom. This enables the phantom to be mounted on the standard Catphan® case. The dose phantom is supplied with a wooden carrying case.

CTP554 32cm Body Dose Phantom: The 32cm Dose Phantom is constructed out of acrylic. 13mm (1/2”) holes are bored into the phantom providing cavities for any appropriately sized CT dose probes. The phantom is supplied with 4 blank acrylic rods to be placed in the holes not used for the dose measurement. For ease of use, a case mount has been added to the phantom. This enables the phantom to be mounted on the standard Catphan® case. The dose phantom is supplied with a wooden carrying case.

16cm Diameter Housing

CTP541 16cm Catphan® Housing: The 16cm Catphan® housing is supplied with a Catphan® mounting bracket enabling it to be mounted off the standard Catphan® carrying case. The housing is cast from a urethane material with a CT number of 0H±5H. The 16cm housing only has 13.5cm of internal capacity in contrast to the 20cm diameter Catphan® housing which has 17.5cm of internal capacity. Due to the smaller capacity of the 16cm housing the modules contained in a Catphan® 500, 412 or 424 will not all fit in the 16cm housing at the same time.
