Primary Outcome Measures

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

Secondary Outcome Measures

Name	Time	Method
<p>Secondary study parameters are metal artefacts. The secondary endpoints are<br /><br>objective and subjective image quality in conventional non-O-MAR images and<br /><br>O-MAR images.</p><br>
