Abstract

The energy broadening parameters for a LYSO:Ce array were determined experimentally in an energy range of 59keV to ∼ 1300 keV for gamma rays. The obtained parameters can be used to improve the Monte Carlo simulation of the spectral behavior of the LYSO-based detectors, especially in PET imaging systems. The detector spectral responses were simulated by the MCNP4c code using the obtained parameters. The obtained results from the simulations were verified using real gamma spectra.
