A small Positron Emission Tomography demonstrator based on LYSO slabs and Silicon Photomultiplier matrices is under construction at the University and INFN of Pisa. In this paper we present the characterization results of the read-out electronics and of the detection system. Two SiPM matrices, composed by 8 × 8 SiPM pixels, 1.5 mm pitch, have been coupled one to one to a LYSO crystals array. Custom Front-End ASICs were used to read the 64 channels of each matrix. Data from each Front-End were multiplexed and sent to a DAQ board for the digital conversion; a motherboard collects the data and communicates with a host computer through a USB port. Specific tests were carried out on the system in order to assess its performance. Futhermore we have measured some of the most important parameters of the system for PET application.

The present study analyzed the differences in distance throwing with heavy and light medicine ball and throwing velocity between handball players of different competitive and professional level. Likewise, the relationship between the three throwing test of progressive specificity was analyzed: throwing with heavy medicinal ball (TH), throwing with light medicinal ball (TL) and throwing velocity (TV). For this purpose, sixty-five professional (P), semiprofessional (S) and non-professional (N) players were evaluated. El presente estudio analizó las diferencias en la distancia de lanzamiento realizado con balón medicinal pesado y ligero y en la velocidad de lanzamiento entre jugadores de balonmano de diferente nivel competitivo y profesional. Igualmente, la relación entre los tres test de lanzamiento, de progresiva especificidad, fue analizado: lanzamiento con balón medicinal pesado (TH), lanzamiento con balón medicinal ligero (TL) y velocidad de lanzamiento (TV). Para ello, sesenta y cinco jugadores profesionales (P), semi-profesionales (S) y no-profesionales (N) fueron evaluados.
