Spiral/Helical CT PhantomModel 061
Optimize collimation and table speed (pitch) to ensure detection of small lesions in the abdominal cavity
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.
The Model 061 contains a CT disk with clinically-relevant spherical targets that are 5, 10 and 20 HU above the background matrix (Plastic Water® LR).
