Mathematical model observers developed and implemented for patient dose optimization in CT

Mathematical model observers developed and implemented for patient dose optimization in CT

A practical challenge to be solved: how to assess image quality by means of a test object? Apply model observers?

Importance and impact of the training module: CT is increasingly used, with associated a substantial impact on the medical exposure in general. Recent years have seen many new evolutions, such as iterative reconstruction and intelligent tube modulation that potentially reduce the dose, but affect image quality too. The effect of these techniques has to be monitored and assessed with clinically relevant measures. New measures, such as model observers, are being developed today but most of them are not yet validated for 3D imaging, like CT.
