Design outcomes

Primary

Measure	Time frame
The main study parameters are the current standard CT-scan and an additional low-dose CT-scan with 40%, 60% or 80% lowered radiation dose. The main endpoint is the subjective image quality at different radiation levels for iterative reconstruction and model-based iterative reconstruction. The subjective image quality, scored by two radiologists, will be leading in the acceptance of low-dose CT images.	—

Secondary

Measure	Time frame
The secondary outcome measure is objective image quality at different radiation levels for iterative reconstruction and model-based iterative reconstruction. Hounsfield Units, noise, contrast-to-noise and signal-to-noise-ratios will be used to determine objective image quality.	—
