Outcome Measures

Primary Outcomes (1)

Data Collection
Number of Participants with raw investigational photon-counting CT scan data along with prior standard of care diagnostic CT exam data/images
1 year

Secondary Outcomes (1)

Image Quality
1 year

Study Arms (1)

Subject's Scanned with Investigational Device

Eligible and consented subjects will be scanned using the investigational Pluto Photon-Counting CT system.

Device: CT Photon-Counting

Interventions

CT Photon-CountingDevice

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.
