Embodiment 1

[0087] Constructing a digital head model by a design method of a human body digital model for radiation protection provided by the present invention includes the following steps:

[0088] S1. Convert the digital model of the voxel head into a digital model represented by gray value through the digital model conversion module. image 3 It is the digital model of the gray-scale head that has been converted.

[0089] S2. Separate the brain from the converted digital head model through the threshold segmentation module.

[0090] The threshold segmentation module is specifically used to separate a single gray value organ, separate all organs within a certain gray value range, preview the extraction results hierarchically in the xy, xz, yz directions, and change the color of the extraction results in the preview interface.

[0091] S3. Generate a preliminary digital model of triangular facets from the separated brain through the curved surface generation module. Figure 4 It is the prelimina...

Abstract

The invention discloses a human body digital model design method, system and model for radiation protection. The design method comprises the following steps: S100, converting a voxel digital model into a grayscale digital model; S200, carrying out organ separation on the grayscale digital model; S300, generating a triangular surface element digital model from the separated organs; S400, repairingthe triangular surface element digital model; and S500, adjusting the volume of the repaired triangular surface element digital model to obtain a final human body digital model. The method can be applied to a rapid prototyping technology so as to replace a traditional physical model casting method, the physical model manufacturing time can be shortened, the physical model manufacturing precision can be improved, customization of the physical model can be achieved, and the method is closer to the requirement for radiation protection in the nuclear industry.

Description

Technical field [0001] The present invention relates to the technical field of radiation protection, in particular to a design method and model of a digital human body model for radiation protection. Background technique [0002] Anthropomorphic Phantom is a physical model that is closer to the real human body. It can more accurately simulate the interaction between the human body and radiation. It has been more and more used in recent years, but it is limited by the current The traditional methods used are difficult to produce, costly, and expensive. It is the focus of research on physical models of radiation dosimetry in recent years. [0003] At present, the most common method for making physical models in the world is the mold casting method, which has the following disadvantages: [0004] 1. The mould casting process is complicated, the cycle is long, and the cost is high. [0005] 2. The quality control of tissue equivalent materials based on thermosetting substrates is diffic...
