Photon Counting Spectral CT

The future of Advanced Imaging

Conventional CT scanners provide a black-and-white image of the human body with relatively poor differentiation of soft tissue.  Complementary medical exams e.g. MRI scans are often required to confirm a diagnosis.  In contrast to conventional CT, Photon Counting CT systems quantify the energy of each individual photon.  As a result, much like we perceive different photon energy levels as different colours of light, PC CT enables clinicians to see X-ray images in full colour and with ultra-high resolution.  PC CT achieves this differentiation while decreasing patient exposure to radiation dose compared to conventional CT.  The additional contrast of PC CT images contains clinically highly relevant and new information which in-turn results in better patient outcomes and reduced cost of care.

While PC CT scans are used to better identify disease or injury of the body, in security screening, the improved image quality and 3D images of passenger bags and parcels will e.g. allow passengers to keep their luggage in their bag as they move through security checkpoints.
