The first and only spectral detector CT system that has been designed for spectral imaging from the ground up (as opposed to modifications of existing CT systems) has just been introduced to the market. Based on a new detector-based system which allows the detection of high and low X-ray photon energies at the same time the new IQon Spectral CT from Philips gives not just anatomical information but also provides the ability to identify and characterize structures based on material content. If desired, such spectral information can be generated retrospectively from every normal scan, without the need for any special protocol or special acquisition mode.
