ANATOMICAL STRUCTURE MODELING BY FINITE ELEMENT METHOD Russian patent published in 2020 - IPC A61B5/00 G06T17/20 G06T7/00 

FIELD: medical equipment.

SUBSTANCE: group of inventions relates to means of generating a finite element model of an anatomical structure. System for generating a finite element model of an anatomical structure based on a matched model of the anatomical structure and binding data comprises an input interface configured to receive: i) model data determining the anatomical structure segmentation model, wherein the segmentation model represents a reference form of the anatomical structure, and ii) binding data linking a portion of the segmentation model to the mesh property, wherein the portion of the segmentation model represents a given analyzed anatomical region, a segmentation subsystem, configured to apply the segmentation model to the medical image of the subject in order to fit the segmentation model to the anatomical structure available on the medical image, with obtaining, therefore, a fitted model providing segmentation of the anatomical structure, wherein the fitted model comprises a part of the fitted model, providing segmentation of the given analyzed anatomical region, a subsystem for generating a finite element model, wherein generation includes construction of a mesh for a part of a finite element model in accordance with the mesh property, and part of the finite element model corresponds to a given analyzed anatomical region. Second embodiment of the system includes an identification subsystem designed to identify a given analyzed anatomical region on a segmentation model and a binding subsystem. Workstation and the imaging device comprise a system for generating a finite element model of the anatomical structure. Methods of generating a finite element model of an anatomical structure according to the first and second versions are carried out by means of corresponding systems and are provided with a computer-readable data medium with a computer-readable code built into it.

EFFECT: use of inventions makes it possible to obtain an optimum balance between stability and simulation computational resources.
