\label{fig:confinement} The number of valid gamma-gamma $\gamma\gamma$  events recorded with depth of interaction DOI  for $2\times2\times30$mm$^3$. two Proteus $2\times2\times30$mm$^3$ LYSO:Ce scintillator crystals.  A uniform distribution convolved with a Gaussian normal with FWHM  ofstandard deviation  1mm is plotted as a dashed black line.This demonstrates the validity of the confinement within the DOI region.
