The QRM-BDC Phantom houses three 18 mm cylindrical inserts providing 0 (water), 100 and 200 mg HA / ccm. The Phantom can be directly placed under an object to evaluate the bone mineral density (BMD) of the object by CT.
As base material of the three inserts CTwater is used. CTwater is a solid water equivalent plastic offering the same X-ray attenuation properties as real water.

The shape of the phantom is slightly bended for a correct fit under the object.

The phantom has a standard length of 200 mm, but is available in different length, up to 700 mm. This is useful for objects measured with an extended scan field.
Other HA concentrations are also available on request. Please contact us to learn more.
