Optimization of Timepix3-based conventional Compton camera using electron track algorithm

The hybrid pixel detector Timepix3 allows the measurement of time and energy deposition an event simultaneously in each 55 μm pixel, which makes a promising approach for compact Compton camera. However, angular resolution camera based on this kind with high density is usually degraded imaging MeV gamma-ray sources, because diffusion energetic electron or photoelectron could trigger many pixels lead to inaccurate interaction position. In study, track algorithm used reconstruct determine point. An demonstrative experiment was carried out, showing that effect significant. measures single layer enhanced 12 degrees (FWHM) 60Co source.
