Our extension (obese) rings are a good choice if you want to test the influences of higher attenuation due to an increased abdominal or chest girth on image quality in CT and other 3D imaging techniques.

The extension rings fits properly on our standard phantoms as there are the QRM-Thorax, QRM-Cardio-Phantom, QRM-Abdomen or the QRM-Liver Phantom.

The rings are basically produced of tissue equivalent material (valid for 120 kVp).

Optionally the rings can be made of fat or water equivalent material (valid for 80 - 140 kVp).

Other materials (specified CT-numbers HU) are available upon request.

Extensionrings are also available with drilled holes for dosimetry purposes.
