PET-CT exam cockpit
Topogram, CT-AC and PET in one exam chronicle.
A clinical PET-CT exam workspace: one exam chronicle runs from topogram to CT-AC to PET, the PET and CT ranges are planned on the same topogram, and the whole-body PET is laid out bed by bed with a time on every bed.
How it works
Three steps, on a real console workflow.
Acquire the topogram
The exam opens on a chronicle of topogram, CT-AC and PET. The topogram is scanned first, in the same order the scanner runs.
Plan both ranges on it
Draw the PET range on the topogram and use Match CT Range so the CT follows the PET. The beds, their overlap and the total time update as the range moves.
Set the beds and scan
Step-and-shoot with a duration per bed, or continuous bed motion. Start the CT-AC, then the PET, and watch the timeline fill bed by bed.
What the cockpit exposes
| Control | Options | What it teaches |
|---|---|---|
| Exam chronicle | Topogram → CT-AC → PET | The fixed order of a PET-CT exam and why the CT comes first |
| Range planning | PET range, CT range, Match CT Range | Covering the PET field with the attenuation CT |
| Acquisition | Step & Shoot or continuous bed motion | Bed-by-bed versus continuous table travel |
| Per-bed time | A duration on every bed, overlap, total time | Spending counts where the disease is, time where it is not |
In the classroom
How programs use it
- Plan a vertex-to-mid-thigh FDG study, then re-plan it with longer beds over the chest and compare the total time.
- Move the PET range without Match CT Range and discuss what an uncovered bed means for attenuation correction.
- Run the same range as step-and-shoot and as continuous bed motion and explain the difference at the console.
