Abstract: A method and computer program for calculating proximal and distal ends of an interlaced device before being positioned in a vascular structure are proposed. The method comprises receiving a three-dimensional image of a vascular structure in which an interlaced device with a singularity at a proximal and/or distal end will be positioned. A central line of said structure which defines a direction in which the interlaced device is to be deployed is traced. A point Pd on the traced central line and the local morphology of the vessel are defined, wherein point Pd indicates the point where the distal end of the interlaced device will start to be deployed. A proximal point Pp is calculated using the distal point Pd and the local morphology of the vessel, both having been defined. The proximal and distal ends are calculated depending on if the singularity is at the proximal and/or distal ends.

Abstract: A method, system and computer programs for computing simultaneous rectilinear paths using medical images are disclosed. The method comprises receiving a 3D medical image comprising voxels representing a volume of an anatomical region of a patient and a preliminary path determined by two points traversing said 3D medical image, wherein said 3D medical image has segmented therein at least one area of interest, the preliminary path comprising a security zone with a given distance; computing a distance map of said area of interest and mapping its voxels to a first value or to a second value depending on a distance threshold, the latter being equal to said given distance of the security zone; selecting the voxels having said second value and projecting them using a frustum that projects the preliminary path onto a single point, to obtain a 2D projected image that includes a plurality of rectilinear paths.

Abstract: A method for calculating values indicative for the local spatial structure of conducting properties of heart muscle tissue. The method uses a continuous ROI where there may exist a CC, each point of the ROI being associated with a value of a given spatial distribution. The method for each one of the points: spans rays within the ROI in multiple 3-D directions using coordinates of a reference coordinate system of each point, providing a structure with a plurality of rays with a given geometry; defines a sequence of sampling points on each ray of said structure; maps the value of the spatial distribution on each defined sampling point of each ray of the structure; classifies each ray of the structure by assigning a single value, providing an associated ray value; and reduces each structure to a single point value in view of said geometry and their associated ray value.

Abstract: The method comprises identifying, in a 3D volume, a zone of a first type (H), a zone of a second type (BZ) and a zone of a third type (C) and: —automatically identifying as a candidate channel (bz) a path running through the zone of a second type (BZ) and extending between two points of the zone of a first type (H); and—automatically performing, on a topological space (H_and_BZ_topo), homotopic operations between the candidate channel (bz) and paths (h) running only through the zone of a first type (H), and if the result of said homotopic operations is that the candidate channel (bz) is not homotopic to any path running only through the zone of a first type (H) identifying the candidate channel (bz) as a constrained channel. The computer program product implements the steps of the method of the invention.
