Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Artifacts are scored independently by two trained judges, based on presence and impact of any disturbance of the image, which can be related back to the spinal immobilization device 2. Radiation exposure is measured using an ionisation chamber and electrometer 3. Noise is measured in SD of the CT values (in Hounsfield Units) of the pixels within 16 circular regions of interest covering 51% of the phantom using ImageJ | — |
Secondary
| Measure | Time frame |
|---|---|
| Overall assessment of the question which device for spinal immobilization performs best from a radiological point of view, with recommendations for clinical use. | — |
