Reproducible Injection Pressure Analysis with a CT-Compatible Perfusion Phantom

Understanding injection pressure behavior is essential for optimizing contrast-enhanced CT examinations. However, capturing reliable pressure data under realistic flow conditions is challenging, particularly when sensor integration risks altering the very parameters being measured.

To overcome this challenge, gKteso collaborated with research and clinical partners to develop a CT-compatible perfusion phantom featuring miniaturized integrated pressure sensors within a modular flow structure. The design enables pressure measurements during controlled injection scenarios while preserving realistic fluid dynamics and minimizing the influence of the sensing technology on the flow itself.

This approach allows researchers to investigate pressure profiles throughout the injection process, including the dynamic transitions between contrast media injection and saline flush phases. These transient pressure changes can provide valuable insights into injector performance, flow behavior, and protocol optimization.

By combining advanced sensor integration with reproducible CT-compatible testing conditions, the perfusion phantom offers a powerful platform for validating injection protocols, evaluating medical devices, and supporting future research in contrast-enhanced imaging. It represents another step toward more precise, data-driven development of CT technologies and improved clinical workflows.
