GE healthcare showed its photon-counting CT system, the Photonova Spectra, at #RSNA2025. It has been a work in progress for years and is now ready for FDA regulatory review. If approved, it will make GE the second vendor with a workhorse photon counting CT system, and the third vendor overall with this technology. Photon counting works differently from traditional CT by counting photons of various energy levels to directly reconstruct an image. The technology can greatly enhance image resolution
