Method for the evaluation of the thickness of a tissue of an organ

A computer-implemented method for the evaluation of an adjusted thickness of a tissue of an organ, the method comprising:

• a. 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;
• b. 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;
• c. step (3) of determining a plurality of trajectories each joining one point (108) of the inner border (102) to one point (107) of the outer border (101);
• d. step (4) of computing for each trajectory (109) the value of a thickness function, wherein said thickness function depends on said trajectory (109) and the classes assigned to the points of the mapping of points (10) through which said trajectory (109) encompasses, wherein the thickness function value is computed from a value of arclength of said trajectory (109) weighted with coefficients depending on the classes by instantiating the arclength function value to 0 and traversing a set of points of the mapping of points by recursively computing a new value of said arclength value for each new traversed point, said new value being computed from the previous value of said thickness function value and from the class assigned to said new traversed point;
• and
• e. step (5) of generation of a 3D model (1000) of said tissue from said mapping of points (10), wherein at least to one voxel of said 3D model (1000) is assigned an adjusted thickness value determined from the value of the thickness function associated to the trajectory (109) encompassing said voxel.
