Conditions

CT Photon-Counting

Outcome Measures

Primary Outcomes (1)

Evaluate feasibility of the photon-counting CT in a clinical setting.
The primary objective of this study is to collect and evaluate raw CT scan data collected using the photon-counting CT.
1 year

Secondary Outcomes (1)

Collect feedback on performance and images generated on the photon-counting CT.
1 year

Study Arms (1)

Subject's Scanned with Investigational Device

EXPERIMENTAL

Device: CT with a photon-counting detector

Interventions

CT with a photon-counting detectorDevice

Enrolled subjects will complete an exam using the photon-counting CT, with or without IV contract as indicated. Images will then be compared with the previously acquired CT conducted as standard of care.
