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. | |
