    摘要: A method for registering a two-dimensional image of a cardiocirculatory structure and a three-dimensional image of the cardiocirculatory structure includes acquiring a three-dimensional image including the cardiocirculatory structure using a first imaging modality. The acquired three-dimensional image is projected into two-dimensions to produce a two-dimensional projection image of the cardiocirculatory structure. A structure of interest is segmented either from the three-dimensional image prior to projection or from the projection image subsequent to projection. A two-dimensional image of the cardiocirculatory structure is acquired using a second imaging modality. The structure of interest is segmented from the acquired two-dimensional image. A first distance map is generated based on the two-dimensional projection image and a second distance map is generated based on the acquired two-dimensional image. A registration of the three-dimensional image and the two-dimensional image is performed by minimizing a difference between the first and second distance maps.

    摘要: A method for fusing a plurality of images. The method includes: acquiring the plurality of images from a plurality of different modalities, each one of the images having a different reference space; and fusing the plurality of images into a common reference space, such common reference space being different from the reference space of each one of the plurality of acquired images. Thus, with such method, a unified process is provided for handling fusion across multiple clinical interventional and/or surgery (i.e., intra-operative) procedures.

    摘要: A method for providing a tool for analyzing an abnormality affixed to a human organ. The method includes: obtaining an image of the organ with the abnormality; separating the image of the abnormality from the image of the organ with the abnormality; mapping a surface of the separated image of the abnormality onto a homeomorphic equivalent template, such template being topologically equivalent to the surface. In one embodiment, the mapping is a continuous, bijective, mapping having a continuous inverse mapping characteristic.
