New CT scanner aims for sharper images with less radiation
NCT ID NCT05838482
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study tested a new type of CT scanner that uses silicon photon-counting technology in 45 adults. Participants had a scan with the new device, and the images were compared to their previous standard CT scans. The goal was to see if the new scanner can produce better quality images in a real hospital setting.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- silicon photon-counting CT scanner
- What this could lead to
- If this new CT scanner works well, it could lead to clearer, more detailed medical images with less radiation exposure for patients.
- What could go wrong
- This was a small, early feasibility study with only 45 participants, so results may not apply to everyone. The new scanner may not prove better than current CT technology.

Inclusion Criteria: * Who are 18 years of age or older * Able to sign and date the informed consent form * Who have in the past 120 days or will in the future 30 days undergo a clinically-indicated CT exam of the head, neck, heart, chest, abdomen, pelvis, or extremities where images are available for this prior scheduled exam Exclusion Criteria: * Who are pregnant or lactating; * Who were previously enrolled in this study; * For contrast-enhanced CT exams, anyone with known or suspected allergy to iodinated contrast agents * For contrast-enhanced CT exams, anyone with known or suspected renal insufficiency as determined by site medical personnel; * Who need urgent or emergent care; * Who have any conditions that, in the opinion of the PI or designee, would interfere with the evaluation of the results or constitute a health hazard for the subject; OR * Who are unwilling to have GEHC personnel present for the CT exam.
