Clinical Study for P-MAR

The purpose of this clinical study is to evaluate the performance of the P-MAR metal artifact reduction algorithm for CT imaging (with metal present) of adult patients (\>18 years old). The study has two objectives: 1. To evaluate the extent of metal artifacts and diagnostic confidence, and overall image quality (independent of metal artifacts) of P-MAR compared to images without metal correction, and compared to O-MAR, for CT images (with metal present) of adult patients (\>18 years old). 2. To demonstrate non-inferiority of P-MAR compared to images without metal correction for the relevant metal groups.
