Obese Extension Rings are used for testing the influence of higher attenuation due to increased abdominal or chest girth on image quality in CT or 3D imaging techniques. The Extension Rings can be used in combination with our (semi-)anthropomorphic standard phantoms: Thorax, Cardio, Abdomen and Liver.

The Extension Rings are available in size M, L and XL and can be manufactured from tissue- or fat-equivalent material. Water-equivalent rings or other materials with specified CT-numbers (HU) are also available upon request. Additionally, a dosimetry version of the Extension Rings with drilled holes for dosimetry purposes is available.
