Article Title: Compton PET: a layered structure PET detector with high performance

doi: 10.1088/1361-6560/ab1ba0

Figure Lengend Snippet: Position decoding using machine learning: (a) 511 keV gamma rays interacting with the Compton PET module at three example positions. (b) The light distributions on the 16×4 array of SiPMs (four 4×4 arrays) corresponding to the three positions in (a). (c) A neural network was trained to determine the gamma ray interaction position from the scintillation light distribution on the SiPMs. (d) In the training set, the gamma beam irradiates the crystal perpendicularly in a 13×13 grid with 1 mm pitch. (e) In the completely independent testing set, the gamma rays irradiate three regions of the crystal: center, edge, and corner. For each region, the center of the beam was scanned across a 13×13 grid with a 0.25 mm pitch. Thus, the test data sampled locations for which no training data was available.

Article Snippet: Since the number of layers, and thus the system sensitivity, can be increased without degrading performance, it may be possible to build an efficient detector for gamma rays with very high energy (several MeV), which can be used for prompt gamma detection for proton range determination in proton beam therapy ( Knopf and Lomax, 2013 ).
