- 7. according to the method for claim 1, it is characterised in that the growth of the lesion is simulated by the default neuropathy model Process and after simulating the deformation process that the organ is influenceed by the lesion generation by the default organ model, institute Stating method also includes：The information in the growth course and the deformation process is preserved using extensible markup language.
- 8. according to the method for claim 1, it is characterised in that the growth of the lesion is simulated by the default neuropathy model Process and the organ is simulated by the default organ model is influenceed by the lesion deformation process of generation and include：Share the growth and institute at least one mutually isolated message group built in advance by way of teleconference State the result of deformation.
- 9. according to the method for claim 1, it is characterised in that before obtaining lesion and the information of organ, methods described is also Including：At least one neuropathy model and at least one organ model are preset using the method for 3D modeling；After carrying out grid data processing at least one neuropathy model and at least one organ model, with binary system text The form of part is stored.
- A kind of 10. lesion analogue means, it is characterised in that including：Acquisition module, for obtaining the information of lesion and organ, wherein, the organ is by the lesion to be influenceed that shape at least occurs The organ of change；Load-on module, for according to the lesion and the organ loading it is corresponding with the lesion preset neuropathy model and with institute State and organ model is preset corresponding to organ；First analog module, for simulating the growth course of the lesion and by the default device by the default neuropathy model The deformation process that organ described in official's modeling is influenceed to occur by the lesion.
