SINGLE- AND MULTI-MODALITY ALIGNMENT OF MEDICAL IMAGES IN PRESENCE OF NON-RIGID DEFORMATIONS USING PHASE CORRELATION

摘要

To provide methods for single- and multi-modality alignment of medical images with non-rigid deformations.SOLUTION: A method comprises: calculating amounts of translation and/or rotation with non-rigid deformations between first and second images of a registered volume of a patient by using a phase correlation method (PCM); on the basis of the calculated amounts of translation and/or rotation, determining an amount of change in a location or orientation of the patient required to correct a second position of the patient to conform to a first position of the patient imaged in the first image.SELECTED DRAWING: Figure 10
