Abstract: A computer-implemented method for the evaluation of an adjusted thickness of a tissue of an organ, the method comprising: step (1) of receiving at least one mapping of points (10) representing said tissue, said mapping of points (10) defining an inner border (102) and an outer border (101) of said tissue; step (2) of segmentation of the mapping of points (10) by classification of each point (11) from the mapping of points (10) into a class belonging to a set of different classes; step (3) of determining a plurality of trajectories (109) each joining one point (108) of the inner border (102) to one point (107) of the outer border (101); step (4) of computing for each trajectory (109) the value of a thickness function depends on said trajectory (109) and the classes assigned to the points of the mapping of points (10) through which said trajectory encompasses; and step (5) of generation of a 3D model (1000) of said tissue from said mapping of points (10), wherein at least to each voxel of said 3D model (1000

Abstract: A method for identifying radiotherapy targets for treating cardiac arrhythmias, which comprises: receiving at least one 3D mapping of points each associated with at least one given feature of a patient's heart and receiving locations of at least one area to be protected, said locations being spatially registered within the reference frame of the 3D mapping; segmenting at least a region in said at least one 3D mapping with selecting a plurality of points of the 3D mapping whose at least one associated given feature matches a predetermined criterion; cropping said segmented region in the 3D mapping with unselecting a plurality of points of the segmented region whose distance to said area to be protected is lower than a predetermined threshold; generating a 3D volumetric model comprising a mesh computed from said cropped region and identified to said cropped region and storing said 3D volumetric model in an electronic file.
