摘要 |
An absorption resolution testing device for use in connection with X-ray imaging devices, for example, computer tomography devices includes a vessel containing a liquid which has X-ray radiation absorption values approximately equal to living tissue and a plurality of smaller vessels disposed within the vessel and the liquid. A second liquid is disposed within the smaller vessels and has absorption values which are different from the absorption values of the first liquid in the vessel.
