innovation for industry

The successful early collaboration with CEA-Leti allowed Siemens Healthineers to prototype what the med- tech company sees as the future of detector modules for whole-body CT," said Jean-Michel Casagrande, the project manager for medical X-ray imaging at CEA-Leti.

The idea of Siemens Healthineers to integrate PCDMs in the future generation of X-ray CT scanners was new and no available technology existed when CEA-Leti began working on this," said Loick Verger, the industrial-partnership manager for X-ray imaging at CEA-Leti. "The technical challenge – low noise at a very high counting rate, two energy classifications, and sufficient maturity to be integrated in an X-ray CT scanner – was tremendous."
Researchers at the Mayo Clinic in the U.S. have evaluated Siemens Healthineers’
photon-counting detector system’s performance in phantoms, cadavers, animals, and
humans. Images of more than 300 patients produced with this technology
consistently demonstrated that the theoretical benefits of this type of
detector technology yield a number of important clinical benefits,”said Cynthia McCollough, professor of
Medical Physics and Biomedical Engineering at the Mayo Clinic.
Publications by our research team have shown improved spatial resolution, decreased radiation or iodine contrast dose requirements, and decreased levels of image noise and artifacts," McCollough said. "Additionally, the ability to simultaneously acquire multiple 150-micron-resolution datasets, each representing a different energy spectrum, is anticipated to lead to new clinical applications."
It is extremely rewarding to see the exquisite images that can be made using the technologies of the detector module that we developed," Verger said. "Seeing for ourselves the clinical benefits of all our R&D efforts motivates our entire team to continue the development of cutting-edge technologies for improving healthcare."
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
