Abstract

Point-based registration is performed by matching a set of homologous points in two spaces. It is common to use such techniques as an aid to navigation during neurosurgical procedures. For many years, statistics concerning Target Registration Error (TRE) have been studied qualitatively using numerical simulations. We present here an expression that gives a good approximation to the distribution of TRE for any given target and configuration of fiducial points.
