Abstract:
1. A method of aligning two sets of medical imaging data, the method comprising: obtaining a first set of image data, captured using a first medical imaging modality, of an anatomical feature of a subject; obtaining a second set of image data, captured using a second medical imaging modality, of the anatomical feature of the subject; providing said first and second sets of image data to a computer and for each image data set, determining, in said computer, an axis of the anatomical feature and a landmark point for the anatomical feature, said landmark point being associated with the axis; in said computer, determining a segmentation of the anatomical feature from each of the first and second image data sets; in said computer, aligning the first and second sets by rigid registration, by comparing the respective axes and landmark points to obtain a first alignment of said first and second image data sets, and refining said first alignment by comparing the segmentation of the feature from the first and second image data sets; and making the first and second image data sets in the refined alignment available in electronic form at an output of said computer.
