Researchers at the University of Wisconsin (UW) in Madison plan to begin a study that will use GE Healthcare's silicon-based photon counting CT system with human subjects in December.

The silicon detectors may enable higher spatial and spectral resolution simultaneously, due to their material purity, geometric design, and multibin technology, GE said.

The device has also been used at the Karolinska Institute in Solna, Sweden. The new prototype now features a larger detector, ECG-gated cardiac scan capability, and faster acquisition speed; the university's work with the system will evaluate its reconstruction methods, image presentation workflows, and clinical benefits for specific pathologies and disease types, according to the firm.
