Conditions

CT Photon-Counting

Brief summary

The purpose of the study is to collect data to evaluate feasibility of the using photon-counting CT in a clinical setting.

Detailed description

Data collected in this study includes an assessment of image quality parameters including spatial resolution, image contrast, and noise that will evaluate the product and how this photon-counting CT technology can be used to reduce the overall radiation dose in CT imaging, and enhance clinical applications for CT technology.

Interventions

DEVICECT with a photon-counting detector

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.

Intervention model description

The single group model will enroll subjects from 5 anatomical areas (lungs, brain/carotid vessels, heart/chest, MSK and abdomen) where CT imaging is applicable and where data on the photon-counting CT is needed to assess feasibility and guide further development of the technology.
