Spiral/Helical CT Phantom
Optimize collimation and table speed (pitch) to ensure detection of small lesions in the abdominal cavity.
| Contains clinically-relevant spherical targets that are 5, 10 and 20 HU below the liver equivalent background matrix. |
The CIRS Helical CT Phantom is designed to test scanning protocols to verify that small low contrast
lesions will be detected. The phantom permits complete testing of low contrast lesion detection when
scan parameters are varied. These parameters include collimation, pitch, reconstructed field of view,
reconstruction algorithms, z-axis interpolators, kVp, mA and rotation time. Testing can be applied
to protocols designed for head and abdomen.
