Blumino: The First Fully Integrated Analog SiPM With On-Chip Time Conversion

Edoardo Charbon, Andrei Ardelean, Emanuele Ripiccini, Andrada Alexandra Muntean, Esteban Venialgo Araujo

Blumino is the first analog silicon photomultiplier with integrated amplifier, comparator and time-to-digital converter (TDC). The combination of a photodetector together with on-chip readout circuitry enables system-level advantages, such as internal para ...

Toward a Full-Flexible and Fast-Prototyping TOF-PET Block Detector Based on TDC-on-FPGA

Edoardo Charbon, Esteban Venialgo Araujo

Typically, a time-of-flight (TOF) positron emission tomography (PET) block detector is built using application-specific integrated circuits (ASICs), since they integrate a high number of channels at a reasonable power consumption and into a small area. How ...

Plug-and-play TOF-PET Module Readout Based on TDC-on-FPGA and Gigabit Optical Fiber Network

Edoardo Charbon, Esteban Venialgo Araujo

Positron Emission Tomography (PET) scanner technology requires the use of a large number of PET detector modules that work in a parallel and synchronous manner. Moreover, system modularity is a desirable feature, that enables technology reutilization for d ...

UTOFPET: a highly scalable TOF-PET detector concept

Edoardo Charbon, Claudio Bruschini, Francesco Gramuglia, Esteban Venialgo Araujo

We present the design and preliminary simulated performance of a highly scalable TOF-PET detector concept. The UTOFPET project aims at the development of a TOF-PET detector module, with beyond-state-of-the-art performance, that is designed to be well suite ...

An order-statistics-inspired, fully-digital readout approach for analog SiPM arrays

Edoardo Charbon, Esteban Venialgo Araujo

In this paper we present a silicon photomultiplier (SiPM) readout system based on a field-programmable gate array (FPGA), which is capable of converting any commercial 16-channel analog SiPM array into a hybrid device with fully-digital readout for applica ...

Small-animal and endoscopic PET detector modules based on multichannel digital silicon photomultipliers

Edoardo Charbon, Augusto Carimatto, Esteban Venialgo Araujo

In time-of-flight (TOF) positron emission tomography (PET), the coincidence resolving time (CRT) has a strong influence on the overall performance. Multichannel digital silicon photomultipliers (MD-SiPMs) are able to obtain several timestamps for gamma pho ...
