Step Interpolation of MR Images with Inter-Slice Gap Correction

This report describes the design of an algorithm for the binary up-interpolation of normal structural MR data in the through slice direction. The method is intended as a pre-processing stage for the measurement of cortical thickkness, where data has already been acquired at lower resolution than would have been ideal. More work is still needed to quantify performance, though a theroetical evaluation is provided here in order to put the method in the contect of other interpolation methods.
