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 stops being a list to memorize and becomes a judgment.
How it works
Three steps, on a real console workflow.
01
Scan with the meter on
Every acquisition reports CTDIvol and DLP. Learners see the dose when they make the decision, not on 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. That is 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.
