To simulate obese patients these Extension Rings can be used with our standard Thorax, Cardio, Abdomen and Liver Phantoms.
​
​Our extension rings are a good choice if you want to test the influences on image quality in CT and other 3D imaging techniques of higher attenuation due to an increased abdominal or chest girth.
​
The extension rings fits properly on our standard phantoms as there are the QRM-Thorax, QRMCardio- Phantom, QRM-Abdomen or the QRMLiver and the QRM-Oval-Body.

The basic material is available as tissue equivalent, fat or water equivalent. Other materials (specified CT-values HU) are available upon request.
