Abstract The innovations brought by Medipix and Timepix detector readout chips have improved medical imaging. Firstly, the small pixel size enables a very high spatial resolution in imaging applications. For this reason, applications, which demand for a high spatial resolution like mammography or dental imaging, were improved both in contrast and spatial resolution. Secondly, the photon processing design of the Medipix and Timepix chips have made possible a completely new field of medical imaging: spectroscopic X-ray imaging. On the occasion of the 20th anniversary of the Medipix2 Collaboration, this article is a review of selected topics related to the use of Medipix and Timepix detectors within the research and application fields of X-ray and gamma imaging in medicine.
