Photonova Spectra

To deliver breakthroughs in spatial resolution and spectral performance, a revolutionary design is required. Silicon has been the industry standard semiconductor for more than 50 years and features an almost-perfect crystalline structure and purity. Our unique solution allows for the simultaneous counting of photons at multiple depth levels, minimizing the potential for pulse pile-up from hundreds of millions of photons. This helps provide exceptional soft-tissue contrast and enhances material characterization capabilities in clinical exams.

The Photonova Spectra design also supports our photon-counting optimized data-management system. This system features rotating-side data storage and high-speed processing, capable of handling up to 50 times more data** and efficiently transferring it to image reconstruction.

Our advanced spectral imaging capabilities are intended to allow you to experience the difference between seeing and knowing so you can confidently detect, characterize and monitor disease.

Photonova Spectra is also designed to enhance material separation for tissue characterization and disease quantification, bringing potentially greater diagnostic confidence in every acquisition across care areas.

A full range of spectral imaging series is generated natively on console and available for transfer to PACS. The full-fidelity spectral data acquisition is intended to provide native DICOM images and material maps to support clinical diagnosis, with improvements of up to 4x enhanced energy discretization¹, 2x higher material map spatial resolution², and 2x improved iodine detectability³.

^{3. Iodine detectability defined as the lowest iodine concentration the system can detect. Photonova Spectra delivers a 2x and greater improvement in iodine detectability, compared to Revolution Apex. It has the ability to detect iodine concentrations down to 0.2 mg/mL at a radiation dose of 8 mGy, using Gammex Multi‑Energy CT Phantom with water and a 0.2 mg/mL iodine insert. Dose based on a 32 cm dosimetry phantom.}
