Monolithic scintillator PET detectors with intrinsic depth-of-interaction correction.
We developed positron emission tomography (PET) detectors based on monolithic scintillation crystals and position-sensitive light sensors. Intrinsic depth-of-interaction (DOI) correction is achieved by deriving the entry points of annihilation photons on the front surface of the crystal from the light sensor signals. Here we characterize the next generation of these detectors, consisting of a 2...
متن کاملTime walk correction for TOF-PET detectors based on a monolithic scintillation crystal coupled to a photosensor array
When optimizing the timing performance of a time-of-flight positron emission tomography (TOF-PET) detector based on a monolithic scintillation crystal coupled to a photosensor array, time walk as a function of annihilation photon interaction location inside the crystal needs to be considered. In order to determine the 3D spatial coordinates of the annihilation photon interaction location, a max...
متن کاملAn alternative mathematical modeling of the scintillation camera and framework for performance analysis of gamma-ray positioning algorithms
Introduction: Substantive amount of work has been done in modeling and analyzing the scintillation camera system processes including positioning and image formation. The goal of this work is to develop a framework for analyzing performance of nonlinear positioning methods upon construction of a mathematical model of the system. In this study, the photodetector array counts are ...

متن کاملGrowth of CsI(Tl) crystals doped with Ca and Tm and investigation of its scintillation characteristics
In this work, the growth of CsI(Tl) crystals as gamma detector was performed using vertical Bridgman method with Ca and Tm co-dopants. For evaluation of the growth crystals, X-Ray Diffraction (XRD), photoluminescence and thermoluminescence spectra as well as recorded gamma spectra were employed. In addition, the scintillation properties including energy resolution, scintillation decay time, abs...
