Methods and systems for 3-d reconstruction and visualization of anatomy using 2-d image slices

A system, comprising:

• a memory storing instructions;
• one or more input/output (I/O) interfaces;
• one or more hardware processors coupled to the memory via the one or more I/O interfaces, wherein the one or more hardware processors are configured by the instructions to:
• acquire a set of 2-dimensional (2-D) image slices of an anatomy at each time-instance of one or more time-instances within an operating cycle of the anatomy, using one or more image acquisition techniques, wherein the set of 2-D image slices of the anatomy acquired at each time-instance comprises one or more multi-directional 2-D image slices;
• generate a point cloud associated with the set of 2-D image slices acquired at each time-instance, wherein the point cloud comprises a plurality of points representing a plurality of pixels associated with the set of 2-D image slices of the anatomy acquired at each of the one or more time-instances;
• create a coherent voxel volume associated with the set of 2-D image slices acquired at each time-instance, from the point cloud associated with the set of 2-D image slices, using a 3-dimensional (3-D) interpolation technique;
• create a 3-D mesh surface for each layered component of one or more layered components associated with the anatomy, using (i) the coherent voxel volume associated with the set of 2-D image slices acquired at each time-instance, and (ii) an iso-surface tracing technique;
• and
• create a structurally complete sliced view of the 3-D mesh surface of the anatomy, from the 3-D mesh surface of each layered component of the one or more layered components associated with the anatomy created for each time-instance, using a mesh manipulation and rendering technique.

One or more non-transitory machine-readable information storage mediums comprising one or more instructions which when executed by one or more hardware processors cause:

• acquiring a set of 2-dimensional (2-D) image slices of an anatomy at each time-instance of one or more time-instances within an operating cycle of the anatomy, using one or more image acquisition techniques, wherein the set of 2-D image slices of the anatomy acquired at each time-instance comprises one or more multi-directional 2-D image slices;
• generating a point cloud associated with the set of 2-D image slices acquired at each time-instance, wherein the point cloud comprises a plurality of points representing a plurality of pixels associated with the set of 2-D image slices of the anatomy acquired at each of the one or more time-instances;
• creating a coherent voxel volume associated with the set of 2-D image slices acquired at each time-instance, from the point cloud associated with the set of 2-D image slices, using a 3-dimensional (3-D) interpolation technique;
• creating a 3-D mesh surface for each layered component of one or more layered components associated with the anatomy, using (i) the coherent voxel volume associated with the set of 2-D image slices acquired at each time-instance, and (ii) an iso-surface tracing technique;
• and
• creating a structurally complete sliced view of the 3-D mesh surface of the anatomy, from the 3-D mesh surface of each layered component of the one or more layered components associated with the anatomy created for each time-instance, using a mesh manipulation and rendering technique.
