Abstract

The invention belongs to the technical field of digital human anatomy models, and discloses a personalized deformation method and system for a deformable digital human anatomical model. The personalized deformation system for the deformable digital human anatomical model comprises an original image data acquisition module, an image data processing module, an image data integration module, a main control module, an anatomical model establishment module, a personalized deformation module, a data storage module and a display module. Through the anatomical form characteristics of the appearance and the interior, the digital human body model can be guided to deform, the appearance form and the interior anatomical structure form of the digital human body model become similar to those of a subject, and therefore a personalized anatomical structure model is constructed. The anatomical position relation between the pipeline structure and the peripheral tissue can be displayed, and personalizeddeformation of the model is achieved; the method and system can be applied to the fields of medical information management, human body modeling simulation, personalized anatomical structure display, patient communication, anatomical education and the like related to user individuals.

Description

technical field [0001] The invention belongs to the technical field of digital human anatomy models, and in particular relates to a personalized deformation method and system for a deformable digital human anatomical model. Background technique [0002] At present, with the advent of the era of big data, 3D digital human body models are used in fields such as medical treatment, human body modeling and simulation, clothing design, sports, etc. individual anatomical differences. If a deformable human anatomical model is established to realize the deformation registration between the digital human model and the individual patient, a personalized digital human similar to the anatomical shape of the patient can be generated through digital human deformation, as a virtual digital representative of the patient itself, for Personalized human anatomy models are provided for doctor-patient communication, simulation, and clinical diagnosis and treatment. [0003] On February 2, 2011,...
