Acquisition Phase | Phase Included | Scan Delay | Respiration Phase | Anatomical Coverage |
Non Contrast | Yes | N/A | N/A | Base of skull through apex |

Scan Comments: Isocentering the patient within the gantry is key to image quality. All scans are performed using the ALARA principle. |
Technical Parameters | Parameters |
kVp | 120 |
Effective mAs | 400 |
Care Dose Reference mAs | N/A |
Time (Rotation) | 1.0 sec |
Average Acquisition Time | 29 sec |
Collimation | 64 x 0.6mm |
Pitch Value | 0.55 |
Scan Direction | craniocaudal |
Comments: Decreasing the rotation time or increasing the pitch will allow for faster scan times when patient motion is a concern. |
Reconstruction Parameters | Soft Tissue | Thin Data | Bone |
Slice Thickness | 5mm | 0.75mm | 5mm |
Reconstruction Spacing | 5mm | 0.5mm | 5mm |
Reconstruction Algorithm | H30 | H20 | H60 |
Window Width and Level | 100 / 30 | 100 / 30 | 2500 / 500 |
Reconstruction Comments: 3D MPR’s can be performed to correct positioning. |
