Medical detector and antidiffusion grid for medical imaging device

Klaus Benedikt Schönenberger, Maïka Réane Guillemin, Thomas Gabella

The invention relates to a medical detector. The medical detector is characterised in that it comprises an antidiffusion grid secured to the detector and in that it comprises an antidiffusion grid mounted on the detector such that it can move between an ac ...

Noise Reduction Techniques and Scaling Effects towards Photon Counting CMOS Image Sensors

Christian Enz, Assim Boukhayma

This paper presents an overview of the read noise in CMOS image sensors (CISs) based on four-transistors (4T) pixels, column-level amplification and correlated multiple sampling. Starting from the input-referred noise analytical formula, process level opti ...

Methylammonium Lead Iodide for Efficient X-ray Energy Conversion

László Forró, Endre Horvath, Bálint Náfrádi

We report on photocurrent generation by X-ray irradiation in methylammonium lead iodide CH3NH3PbI3 single crystals. We observed 75% of charge collection efficiency in millimeter sized samples. This efficiency is partially due to the high photon absorption ...
