Abstract

A method for fabricating a physical simulation device of an internal element of interest (9) located inside an object. The method comprises the steps of: receiving one non-destructive measurements of an imaged region, determining a three dimensional model of the imaged region (8) and materials of the object in locations of the three dimensional model, generating first and second volumetric models (18) from the three dimensional model, computing a deformed configuration of the first volumetric model under predefined loads and constraints on the basis of assigned intrinsic material properties, assigning to elementary volumetric elements of the second volumetric model (18) materials on the basis of the deformed configuration of the first volumetric model, fabricating a simulation device of the internal element of interest according to the second volumetric model (18) with the assigned materials.

Core Innovation

The invention provides an organ simulation device configured to simulate a portion of an in vivo organ and additional portions of a body surrounding the in vivo organ portion. The organ simulation device includes an organ replica having an internal surface topology and an external surface topology, and the organ replica is formed from a plurality of materials having different respective intrinsic material properties.

The internal surface topology of the organ replica replicates the internal surface topology of the in vivo organ portion. The external surface topology does not match the external surface topology of the in vivo organ portion or the external topology of the surrounding body portions. The materials of the organ replica are selected and arranged so that the mechanical behavior of the organ replica in a deformed configuration substantially matches the mechanical behavior of the in-vivo organ portion surrounded by the surrounding body portions.

In example implementations, the organ simulation device uses volumetric modeling and finite element simulation to support the material selection and arrangement, including a first volumetric model with assigned intrinsic material properties and computing a deformed configuration under predefined loads and constraints. The method then assigns simulation materials to elements of a second volumetric model based on the deformed configuration, and the device is fabricated according to the second volumetric model.

Claims Coverage

The partial content contains one independent claim directed to an organ simulation device with multi-material intrinsic material properties arranged to match in-vivo mechanical behavior in a deformed configuration.

Across the independent claim, the key inventive concept is an organ replica that preserves the in-vivo internal surface topology while using multiple materials with different intrinsic material properties, arranged so that the replica’s mechanical behavior in a deformed configuration substantially matches the in-vivo organ behavior within surrounding body portions.
