Embodiment

[0047] Embodiment: Construction of digitized virtual hand anatomy

[0048] 1 Materials and methods

[0049] 1.1 Specimen selection and pretreatment

[0050] Three fresh healthy adult hand specimens were taken (wrist joints were preserved). The specimens should have no organic damage (CT scan before treatment), and their main anatomical parameters were representative. After the proximal ulnar and radial arteries of the specimen were freed, the vessels were flushed with 5% sodium citrate saline until the effluent was clear and the specimen was pale.

[0051] 1.2 Specimen perfusion

[0052] 1.2.1 Pouring material

[0053] In this experiment, the material of self-curing dental trays was used, and the contrast agent was mercury sulfide. The formula is: 30-35g of self-setting dental tray powder, 65-70g of self-setting dental tray water, 30ml of dibutyl phthalate, 10-15g of Chinese silver vermilion (containing mercury sulfide), and the above materials can be purchased in the mark...

Abstract

The invention relates to a digitized virtual hand anatomy construction method, which includes the following steps: A, specimen selection and pretreatment; B, specimen injection; C, CT scanning for data set acquisition; D, visualized three-dimensional reconstruction of the hand on a common PC platform through Mimics software developed by Belgian Materalise company, which includes the steps of a, three-dimensional reconstruction of the outline of the hand; b three-dimensional reconstruction of bones; c, three-dimensional reconstruction of the artery of the hand; d, three-dimensional reconstruction of the tendons of the hand. The construction method for the first time realizes comprehensive digitized three-dimensional reconstruction of a hand anatomy and converts two-dimensional pictures commonly used in clinics into three-dimensional pictures, which is good for further improvement of understanding of human hand and provides scientific basis for clinical diagnosis, treatment program formulation and related operations.

Description

technical field [0001] The invention relates to a method for constructing digital virtual human organs, in particular to a method for constructing digital virtual hand anatomy. Background technique [0002] Digital virtual technology has become a hot issue in the field of life science and information science. Since the U.S. National Library of Medicine first proposed the "Visible Human Project (VHP)" in 1989, South Korea, Japan and other countries have also proposed similar research projects. Digital virtual human body refers to the digitization of human body structure, and through computer technology and image processing technology, a seemingly real simulated human body appears on the computer screen. At present, the research on "virtual human" at home and abroad is in the stage of "virtual visual human", which can also be called "virtual anatomical human" or "virtual geometric human". The goal is to virtualize the shape and structure of the human body. The basic framewor...
