GE HealthCare introduced Photonova Spectra, its photon-counting computed tomography (PCCT) system, to the Greek medical community on 30 October, at the 3rd Panhellenic Congress of Medical Physics and the 27th Inter-University Congress of Radiology.
Based on GE HealthCare’s proprietary Deep Silicon detector technology, Photonova Spectra is designed to deliver high spectral and spatial resolution, while enabling ultra-high-definition (UHD) imaging with 8-cm coverage and on-demand spectral imaging.
It is also designed to support rapid image acquisition, precise visualisation of anatomical structures and improved differentiation between materials. Its introduction in Greece marks a significant milestone, following the granting of CE marking in August 2026.
Advancing photon-counting CT with Deep Silicon technology
Photon-counting computed tomography marks a significant advance in medical imaging. Unlike conventional CT systems, which convert X-rays into light when they are detected, photon-counting technology directly detects and counts individual X-ray photons, while also determining their energy.
This approach enables higher spectral and spatial resolution, as well as improved tissue characterisation.
This gives clinicians access to more information, helping to improve the reliability of disease detection and diagnosis.
Photonova Spectra takes this a step further by using Deep Silicon, an innovative detector material designed to enhance spectral imaging capabilities. The aim is to support more accurate assessment of lesions and monitoring of treatment using CT.
Enhancing clinical assessment and workflow efficiency
Photonova™ Spectra is designed to support a wide range of clinical applications, including neurology, oncology, cardiology, chest imaging and musculoskeletal examinations.
Its capabilities give clinicians detailed anatomical and spectral information that can support clinical assessment and treatment monitoring, as well as research into quantitative imaging and tissue characterisation.
The system is also designed to make efficient use of the large volumes of data it generates.
Using NVIDIA accelerated computing technology, it can process up to 50 times more data¹ than conventional CT.
This capability enables advanced image reconstruction techniques and the generation of highly accurate results, with the aim of supporting clinical decision-making and a smoother workflow.
Commenting on the launch of Photonova Spectra in Greece, Spyridon Gikas, GE HealthCare’s general manager for Greece, Cyprus and the Balkans, said:
“Healthcare systems face rising needs and complex diagnostic demands. In this environment, access to clear and timely diagnostic information is more important than ever.
Photonova Spectra combines advanced imaging with workflow innovations, giving doctors more comprehensive clinical information and helping to simplify CT examinations. Presenting this technology to medical imaging professionals in Greece is an important step towards supporting doctors and enabling more personalised, evidence-based decisions about patient care”.
