Abstract
There is provided a method for geometrical reconstruction of an internal anatomical structure using at least one processor based on a set of contours derived from the internal anatomical structure, the set of contours including a first subset of long-axis contours obtained based on a first set of long-axis images of the internal anatomical structure. The method includes: adjusting the set of contours, comprising adjusting the first subset of long-axis contours to correct for motion artefacts in the first set of long-axis images; and deforming a template three-dimensional (3D) surface mesh preconfigured for the internal anatomical structure's type into a deformed 3D surface mesh based on the adjusted set of contours to obtain the geometrical reconstruction of the internal anatomical structure. In particular, the internal anatomical structure is a heart. There is also provided a corresponding system for geometrical reconstruction of an internal anatomical structure.
