Overview

CT phantoms assess spatial resolution contrast detectability and dose metrics. They support routine QA and protocol validation for CT scanners. Phantoms enable benchmarking and multicenter harmonization.

Dose Measurement

Phantoms include dosimetry inserts for CTDI and dose profile measurements. Accurate dose assessment informs protocol optimization and patient safety. Regular dose audits track trends and compliance.

Image Quality Metrics

Resolution bars and low contrast inserts evaluate scanner performance. Reconstruction algorithm testing uses phantoms to compare image quality across settings. Results guide protocol adjustments and vendor support.

Research and Development

Phantoms support development of new reconstruction methods and spectral CT validation. Custom phantoms simulate clinical scenarios for algorithm testing. Collaboration with vendors and research groups advances quantitative imaging.
