Method and system for generating a 3d parametric mesh of an anatomical structure

A system for generating a 3D parametric mesh of an anatomical structure for storing multi-domain data therein, the system comprising:

• at least one processor;
• and
• a non-transitory storage medium operatively connected to the at least one processor, the non-transitory storage medium storing computer-readable instructions;
• and
• the at least one processor, upon executing the computer-readable instructions, being configured for:
• receiving a plurality of anatomical segments of at least a portion of an anatomical structure in a body of a given patient having been obtained from segmentation of a set of images having been acquired by a medical imaging apparatus, the set of images comprising at least one image of at least the portion of the anatomical structure in the body of the given patient;
• receiving a 3D mesh for representing the anatomical structure, the 3D mesh comprising:
• a plurality of concentric 3D mesh layers, each one of the plurality of concentric 3D mesh layers comprising a same predetermined number of nodes;
• determining at least one respective set of nodes in the 3D mesh corresponding to at least one respective anatomical segment of the plurality of anatomical segments to obtain a respective correspondence rule therebetween;
• and
• encoding, using the correspondence rule, the at least one respective set of nodes of the 3D mesh with a respective set of features from the at least one respective anatomical segment to obtain a 3D parametric mesh, each node of the at least one respective set of nodes in the 3D parametric mesh being associated with a respective plurality of feature channels comprising the respective set of features.
