Description
Our group at the “Institut de Physique Nucléaire de Lyon” (IPNL) is working for
physics and detectors for medical imaging. We are presently developing, for a
demonstration purpose and within the Crystal Clear international collaboration, a
small animal PET scanner that should have enhanced slow control and data acquisition
features. We also investigate a feasibility study of an online PET dedicated for
inline and in-situ dose deposition control in hadrontherapy. Our basic block
detector is a compound of a single block scintillating crystal whose response is
sampled by a multi-anode photomultiplier with its proper embedded acquisition
readout chain. After a presentation of the characteristics of our basic experimental
setup, we discuss our calibration algorithm that allows energy, impact point and
depth of penetration measurement with good accuracy within the crystal block.
Moreover, the algorithm is iterative, easily implemented and dependent from the
number of sampling photomultiplier anodes a sub-millimeter resolution in all of the
three coordinates is achievable.
