CT Scan Protocol
The prevention of motion is critical for 3-D imaging and modeling. The technologist must take the time to instruct the patient on the importance of holding completely still during the scan.
Proper positioning of the patient is imperative for successful scanning. The following instructions are very important. Read them very carefully before scanning.
TECHNICAL FACTORS/SCANNING THE PATIENT
FOR ALL SCANNERS:
| Slice Thickness: |
Acetabulum/Pelvis Primary or Revision Hip Replacement Patella - Femoral Groove Knee - Primary or Revision Shoulder Elbow |
| Field of View: | Magnify or zoom image so it fills the entire screen without cutting off any of the anatomy for imaging. Must not be changed during the scan. |
| Table Position: | The CT couch must not be raised or lowered between slices. The X and Y centering must not be altered between slices. |
| Matrix: | Quality images can be obtained from any scan matrix, although a high resolution 512 x 512 matrix should be used whenever possible. |
| Algorithm: | A STANDARD OR SOFT TISSUE ALGORITHM with no edge enhancement should be used. DO NOT use bone algorithm. |
| Slice Spacing: | All slices must be contiguous or overlapping. Slice thickness and table increment is dependent on anatomy, you may change slice thickness in the middle of the scan but be careful not to leave a space that is not scanned when making technical changes. Example: To change from a 3mm slice thickness to 2mm, the table must be backspaced 1mm before executing the 2mm scan. |
| Data Collection: | We accept CD-ROMs with uncompressed axial image data in DICOM format off all CT scanners. We also accept 5 1/4" optical disk that are 1.2 or 2.3 GB uncompressed data.
