Abstract
A method of registering 3-dimensional digitized images to 2-dimensional digitized images during a medical procedure includes providing a pair of correctly-registered training images L={l, l} and their joint intensity distribution p(i, i), wherein iand iare reference and floating images, respectively, providing a pair of observed images O={o, o} and their joint intensity distribution p(i, i), mapping a marginal intensity distribution of the observed pair O={o, o} to a marginal intensity distribution of the training pair L={l, l}, and estimating a set of parameters T that registers image oto image oby maximizing a weighted sum of a Jensen-Shannon divergence (JSD) of a joint intensity distribution of the observed pair and a joint intensity distribution of the training pair and a similarity measure between the observed images.
