Embodiment 1

[0030] see figure 1 , 3 As shown, the medical assistance system based on augmented reality and finite element analysis includes medical image data, cloud database, model extraction and optimization part, and AR display part;

[0031] The medical imaging data is two-dimensional image data such as CT or MRT of the patient to be treated;

[0032] The cloud database is a database that is connected to an external data network and realizes the collection and storage of multiple pictures;

[0033] The model extraction and optimization part includes image data processing module, optimization processing module and conversion module;

[0034] The image data processing module is used to process two-dimensional image data such as CT or MRT of the patient through threshold processing and selection of segmented regions to generate a three-dimensional rough extraction model map, and pass it to the optimization processing module under user selection;

[0035] The optimization processing mo...

Embodiment 2

[0051] see Figure 1-4 As shown, the difference between this embodiment and the first embodiment lies in: the medical assistance system based on augmented reality and finite element analysis also includes a biomechanical analysis part;

[0052] The conversion module is used to generate the FBX file format of the received fine extraction model through format conversion and transmit it to the AR display part, and generate the Prt file format to transmit to the biomechanical analysis part.

[0053] The biomechanical analysis part includes a second receiving module, a selection module, a filling module, an adjustment module and a calculation analysis module;

[0054] The second receiving module is used to import the generated Prt file format into this part to form a mechanical analysis and detection of the model;

[0055] The selection module is used to define the areas of main damage, main use and force application in the model;

[0056] The filling module is used to fill the m...

Abstract

The invention belongs to the technical field of medical assistance, and particularly relates to a medical assistance system based on augmented reality and finite element analysis and a use method, the medical assistance system comprises medical image data, a cloud database, a model extraction optimization part, an AR display part and a biomechanical analysis part; the AR display part comprises a first receiving module, an adjusting module, an output module and a display device; the biomechanical analysis part comprises a second receiving module, a selection module, a filling module, an adjusting module and a calculation and analysis module; two technologies of finite element analysis and augmented reality are applied to medical treatment, and the situation that a doctor can only check the illness condition through CT or nuclear magnetic resonance two-dimensional images traditionally is changed; and through augmented reality formed by the AR display part and biological finite element analysis formed by the biomechanical analysis part, the problem of high difficulty in preoperative planning and postoperative specifying of exclusive rehabilitation measures of a patient during existing medical treatment is effectively solved or improved.

Description

technical field [0001] The invention belongs to the technical field of medical assistance, and in particular relates to a medical assistance system based on augmented reality and finite element analysis and a usage method. Background technique [0002] Augmented reality, referred to as AR, is realized by using various technologies such as 3D modeling, real-time tracking and registration, and intelligent interaction. It is now widely used in 3D games, intelligent interaction, training and teaching, etc. Images, 3D models, videos and other information are simulated and mapped to the real world, and the two kinds of information obtained by the simulation model and the real model complement each other, so as to achieve the "enhancement" of the real world. [0003] Finite element analysis is a relatively mature technology nowadays, which refers to the simulation of real physical systems (geometry and load conditions) by using mathematical approximation methods, using simple and i...
