Abstract

The invention relates to an angiography technology and an anatomy and casting technology of a body sample and specifically discloses a body sample angiographic filler and a preparation method thereof. The filler consists of E-51 epoxy resin, 2,4,6-tri(dimethylamino methyl) phenol (DMP-30), polypropylene glycol diglycidyl ether (D-1217), a T-31 epoxy resin curing agent and a metal oxide powder contrast agent (zinc oxide, titanium dioxide, cuprous oxide and chromium sesquioxide). The angiographic filler disclosed by the invention is simple to prepare, easy to regulate in concentration and color and hard to decolorize, and has the characteristics of being rapid in automatic coagulation, small in percentage of contraction, high in toughness, low in cost and the like. CT reconstruction of blood vessel images of a human body sample or an animal body sample (or organ) have the advantages of being clear, full, continuous, free of fake shadows and burrs and the like.

Description

technical field

[0001] The invention relates to angiography technology and anatomical casting technology of cadaveric specimens.

[0002] technical background

[0003] Since 1990, many countries have invested a lot of talent and financial resources in the "Visible Human (VH) Program", and achieved gratifying breakthrough results. However, during the processing of the VH dataset, the small blood vessels could not be segmented. Even the powerful and technically advanced Voxel-man researchers could only use the TubeEditor to artificially simulate small blood vessels. In 2002, Chinese anatomists used a combination of angiography technology and anatomical casting technology to successfully reconstruct some human blood vessels from the "Chinese Digital Human (CDH)" dataset for the first time in the world. (Digital Human, DH)” has made a significant contribution. At present, gelatin-lead oxide angiography has become a routine method for the study of vascular anatomy, and has been ...
