Signal processing of velocity streams of a signal flow for coherent mapping of an anatomical structure

A system comprising:

• a memory storing program code for a mapping engine;
• at least one processor executing the program code to cause the system to perform:
• subdividing, by the mapping engine, an anatomical mesh of at least a part of an anatomical structure to one or more other meshes of the anatomical structure, the one or more other meshes being more granular than the anatomical mesh;
• interpolating, by the mapping engine, local activation time values and velocity values for the one or more other meshes;
• tracing, by the mapping engine, a path of velocity vectors on the one or more other meshes in accordance with the interpolation of the local activation time values and velocity values;
• and
• projecting, by the mapping engine, the path on the anatomical mesh to provide an enhanced visualization of the anatomical structure.
