TL;DR: In this article, the authors studied the feasibility of maximum likelihood estimation for computing the true gamma-ray photo-conversion position from the centroids and the standard deviation of the light distribution.

DOI measurement with monolithic scintillation crystals: A primary performance evaluation
Christoph Lerche,A. Ros,R. Gadea,R.J. Colom,F.J. Toledo,V. Herrero,J.M. Monzo,A. Sebastia,D. Abellan,F. Sanchez,C. Correcher,Antonio González,A. Munar,Jose M. Benlloch +13 more
TL;DR: In this article, the authors report a first assessment of image quality enhancement achieved by the implementation of depth of interaction detection with monolithic crystals, based on analogue computation of the standard deviation with an enhanced charge divider readout.
Proceedings ArticleDOI
Impact of the scattering coefficient of scintillation crystals (LYSO and LSO) on depth of interaction resolution
A. Ros,Ch.W. Lerche,F. Sanchez,J. Segura-Ruiz,R. Ortuno,J. Marti,Andrés Cantarero,A. Sebastia,Jose M. Benlloch +8 more
TL;DR: In this paper, measurements of depth of interaction and its resolutions for three different scintillation crystals (one LSO and LYSO of two different providers) are presented, showing that different values of the scattering coefficient for the different crystals are consistent with the measured resolutions for the depth OF interaction and prove the strong impact of the α scatt for each crystal on the ΔDOI.
