Embodiment Construction

[0044] This patent research has been supported by the scientific research project project of the Hunan Provincial Health and Health Commission (20191044); the Hunan Provincial Natural Science Foundation-Youth Fund Project (2018JJ3850); the Hunan Provincial Key Research and Development Program-Key Research and Development Project in the Field of Social Development (2017SK2161).

[0045] The method is based on the existing two-dimensional image completion algorithm deep convolution against the generative network model. The present invention improves the algorithm, and after the improvement, the method in the present invention can adapt to three-dimensional CT images, and perform morphological completion in three-dimensional space. For ease of understanding, the following examples take the jawbone as an example to specifically illustrate the present invention:

[0046] figure 2 The manual completion process of traditional surgical simulation is given, in which the left side is ...

Abstract

The invention discloses a method of complementing a diseased bone to obtain a bone expected reference model. The method has the technical effects that the complementing form after bone lesion removalcan be quickly obtained, and the complementing form is basically close to natural bones; the method is not limited by complementation when the range of lesions is too large; and under the condition that clinical data and operator experience can not be considered, the trained model and the method can also be copied, and basic bone completion is completed. Therefore, the technical difficulty of theskeleton expected reference model is reduced, the manufacturing efficiency of the skeleton expected reference model is improved, and technical popularization and copying are facilitated.

Description

technical field [0001] The invention relates to a method for complementing diseased bones to obtain expected bone reference models. Background technique [0002] Tumors, trauma and various operations often cause bone lesions. Most patients have significant bone deformation when they see a doctor. At this time, it is often difficult for doctors to obtain the accurate shape of the patient's bone before the disease. [0003] At the same time, the bones of the human body have strong specificity, and the shape of each person's bones is more or less different, which makes it impossible to use a general bone model as a surgical reference, which increases the uncertainty of the surgical effect. It is therefore often necessary to design a skeletal prospective reference model using digital techniques. [0004] Although medical science is limited by materials at this stage, it is not yet possible to directly provide patients with a bone prosthesis for their use based on the computer...
