“…Our simulation results show very good agreement with published results for similar configurations [3], [18] and suggest that this relatively simple system models are able to describe the most significant system features and provide realistic stimuli to the VHDL, fact that eases the implementation and validation of the implemented algorithms on hardware as well as enables the estimation of system performance. As an example, the availability of synthetic stimuli gave valuable insight for the design and optimization of the digital timestamp generation block and allowed for the detection of a very subtle code bug which would have been very difficult otherwise.…”

“…The next stage has been the configuration of the Simulink blocks to model an analog front-end consisting of a 16 16 LSO(0.22 0.22 1.2 cm)/GSO(0.22 0.22 1.2 cm) phoswich coupled to a Hamamatsu H5000 PS-PMT [15], with optical grease, based on the observations and measurements carried out by several authors [3], [6], [7], [12], [16]- [18]. Given the scintillator, coupling and PMT properties the overall efficiency is set to 10% which is consistent with previously reported values [7], [19].…”

“…Position sensitive photomultiplier tubes ͑PSPMTs͒ were introduced by the end of the 1990s and they fulfill this need. The design of their dynode stage and cross wired or pixilated anode maintains position information during electrons multiplications, 92 making possible the construction of small field of view detectors with very high resolution. Several improvements in the field of electronics have also assisted to the improvement of systems sensitivity, as well as dramatic decrease in their overall size and cost.…”

“…Ο πίνακας 7.1 [10] συνοψίζει τα χαρακτηριστικά των κρυστάλλων που χρησιμοποιούνται στο PET και το SPECT. [45]. Η θέση υπολογίζεται από την πληροφορία ενός φωτοπολλαπλασιαστή και όχι από την επεξεργασία του σήματος περισσοτέρων.…”
