What this trial studies

This study aims to collect data on the clinical utility of photon-counting CT technology. It will assess various image quality parameters such as spatial resolution, image contrast, and noise, with the goal of demonstrating how this technology can reduce radiation exposure during CT imaging. The findings will support regulatory submissions and enhance clinical applications of CT technology. Participants will undergo clinically-indicated CT exams, and their imaging data will be analyzed for quality assessment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who are scheduled for a clinically-indicated CT exam within a specified timeframe.

Not a fit: Patients who are pregnant, have allergies to contrast agents, or require urgent care may not benefit from this study.

Why it matters

Potential benefit: If successful, this technology could lead to safer CT imaging with reduced radiation doses for patients.

How similar studies have performed: Other studies have shown promise in improving CT imaging technology, but this specific approach is relatively novel.
