Dose training
CTDIvol and DLP on every scan — ALARA taught by doing.
No competitor teaches dose the way a live readout does. Halve the mAs and watch the noise climb; extend the range and watch DLP grow. Optimization becomes judgment, not memorization.
ScanFlo CT — Exam · Topogram + dose
How it works
Three steps, on a real console workflow.
01
Scan with the meter on
Every acquisition reports CTDIvol and DLP — dose is visible at the moment of decision, not in a slide next week.
02
Trade dose for quality
Change one exposure factor at a time and compare noise, contrast and dose across runs.
03
Build the ALARA loop
Learners iterate to the lowest dose that still answers the clinical question — the actual job.
What moves the numbers
| Change | Dose effect | Image effect |
|---|---|---|
| mAs −50% | CTDIvol −50% | Noise +41% |
| kVp 120→100 | Dose ↓ ~35% | Contrast ↑, noise ↑ |
| Pitch 0.9→1.2 | Dose ↓ | Helical artifacts risk ↑ |
| Scan range +5 cm | DLP ↑ proportionally | No diagnostic gain |
In the classroom
How programs use it
- Dose audits: learners justify every scan's CTDIvol against a reference level.
- The 'half-dose challenge': lowest dose that keeps the finding visible.
- Range discipline drills scored by DLP per indication.
