There is currently a large interest in photon counting CT detector research in both academia and industry. There are several detector systems and strategies to handle major challenges such as the very high count-rate, while the energy information for each photon is retained. Another challenge is cross talk, which may compromise the energy estimation for the photons and can cause double counts, which gets worse with smaller pixel size. If implemented in the clinic, photon counting CT will likely enable a dose reduction when this is important, as for example in pediatric CT. Photon counting CT will also make possible quantitative measurements, energy weighting and/or tissue decomposition techniques that can be of great importance for a number of imaging tasks
