Abstract:
1. An image registration method for use in medical imaging, the method including the steps of: providing a sequence of images each one including a digital representation of a body-part under analysis, selecting a reference image within the sequence, the remaining images of the sequence defining moving images, and re-aligning at least one portion of a moving image with respect to the reference image, a) defining a delimitation mask identifying a region on the reference image with which the at least one portion of the moving image has to be re-aligned, and a feature mask identifying a further region on the reference image within which the re-alignment is calculated, b) determining an optimized transformation for compensating a displacement of the moving image with respect to the reference image by optimizing a similarity measure between: c) transforming the at least one portion of the moving image according to the optimized transformation.
