Multilayer position-sensitive 10B-RPC thermal neutron detectors offer an attractive combination of
sub-millimeter spatial resolution and high (>50%) detection efficiency. Here we describe a new
position reconstruction method based on statistical approach. Using experimental data, we compare
performance of this method with that of the centroid reconstruction. Both methods results in a
similar image quality and spatial resolution. However, the statistical method allows to improve the
image quality at the detector periphery, offers more flexible (and more easily configurable) event
filtering and allows to develop automatic quality monitoring procedures for early detection of
situations when a change in the detector operation conditions starts to affect reconstruction quality.
