GratXray was founded in 2017 as a spin-off of ETH Zurich and the Paul Scherrer Institut (PSI), bringing over a decade of research expertise in grating-based X-ray interferometry and CT imaging into commercial development. The company was founded by Prof. Dr. Marco Stampanoni, Prof. Dr. Zhentian Wang, Dr. Martin Stauber, and Martin Jermann, together with the Paul Scherrer Institute (PSI).
In its founding year, GratXray received the prestigious Swiss Technology Award 2017 in the Inventors category, marking early recognition of the breakthrough potential of compression-free breast CT imaging. Building on this success, GratXray collaborated with its academic partners to develop a prototype breast CT system integrating a grating-based interferometer, proving the physical principles and solving key engineering challenges. The interdisciplinary team published their development and results in several international scientific journals.
After demonstrating these scientific breakthroughs, GratXray made a strategic decision: to advance clinical breast CT imaging by first addressing challenges accessible with conventional technology, while maintaining a clear path toward grating interferometry integration. This pragmatic approach led to senoa, our dedicated breast CT scanner optimized for immediate clinical deployment, with architecture designed to incorporate grating technology once all development milestones are achieved.
In 2024, GratXray successfully closed its first financing round, enabling expansion of the operational team with key expertise in engineering, regulatory affairs, and quality management. The company established operations at Healthtechpark Zurich in Schlieren, where the team is now focused on bringing senoa to market.
Combining scientific excellence with patient-centered innovation, our multidisciplinary team brings deep expertise in medical physics, imaging technology, intellectual property, and regulatory affairs. As an ISO 13485 certified organization with comprehensive IP protection, we maintain rigorous quality standards as we build a portfolio of breakthrough imaging solutions that improve diagnostic accuracy, patient comfort, and healthcare outcomes.
