Abstract
A method for non-rigid multi-modal registration of digitized images includes providing a reference image and an alignment images acquired from different imaging modalities to a graphics processing unit (GPU), initializing a deformation field for registering said reference image and said alignment image, computing marginal and joint intensity histograms of the reference image and the alignment image as registered by said deformation field, computing gradients of the reference and registered alignment images and of their respective marginal and joint intensity histograms, smoothing said histograms and gradients using Gaussian filters, calculating a new deformation field using said smoothed gradients, and registering said alignment image to said reference image using said deformation field.
