Noise magnitude reduction and NPS peak frequency shift in percentage differences for PCD-CT in comparison with EID-CT at the three investigated patient sizes.
| Phantom Size | Noise Magnitude Reduction (%) | Peak Frequency Shift (%) |
|---|---|---|
| Small | −9 | 47 |
| Medium | −33 | 37 |
| Large | −38 | 27 |
NPS—noise power spectrum; PCD-CT—photon-counting computed detector computed tomography; EID-CT—energy-integrating computed tomography.
