Design outcomes

Primary

Measure	Time frame
Main study parameters/endpoints: The main study parameters are a current standard care CT scan and an additional low-dose CT scan with 20%, 40%, 60% or 80% lowered radiation dose. The main endpoints are the objective and subjective image quality at different radiation dose levels for iterative reconstruction and model-based iterative reconstruction.	—

Secondary

Measure	Time frame
Secondary study parameters are metal artefacts. The secondary endpoints are objective and subjective image quality in conventional non-O-MAR images and O-MAR images.	—

Countries

The Netherlands
