TL;DR: The Clear-PEM scanner for positron emission mammography under development is described in this paper, which is based on pixelized LYSO crystals optically coupled to avalanche photodiodes and readout by a fast low-noise electronic system.

TL;DR: In this paper, a front-end application specific integrated circuit (ASIC) for the readout of common cathode Silicon Photo-Multiers arrays is presented with the following features: wide dynamic range, high speed, multi channel, low input impedance current amplifier, low power (≈10mW per channel), common cathodes connection, directly coupled input with common mode voltage control and separated timing and charge signal output.

TL;DR: Experimental validation of the detection techniques, namely the basic properties of the radiation sensors and the ability to measure the depth-of-interaction of the incoming photons, are presented.

TL;DR: A PET insert for existing magnetic resonance imaging (MRI) equipment, to be installed in a collaborating hospital and used for clinical PET-MRI of the human brain is developed.

TL;DR: First results on PET coincidence performance indicate spatial resolutions as good as 2.1 mm FWHM for SSRB/FBP reconstruction of tomographic data obtained using a simple PET demonstrator based on a pair of monolithic detector blocks with ASIC readout.
