Embodiment 1

[0033] This embodiment is the process of making plane tomographic specimens, such as image 3 As shown, the plane tomographic specimen is the plane tomographic specimen of the 12th thoracic vertebra, so the realization method of making the plane tomographic specimen is as follows:

[0034] The first step is to make digital pictures of planar tomographic specimens

[0035] Select a suitable digital picture from the established human body information database of tomographic specimens. The digital picture is a digital picture obtained after high-resolution scanning. The digital picture can clearly reflect the adjacent structures in the human body tomography, which is consistent with the real thing .

[0036] Since the plane tomographic specimen produced this time is the 12th thoracic vertebra, the selected digital picture is a cross-sectional view of the 12th thoracic vertebra. This cross-sectional view is a high-resolution digital picture, and the cross-sectional structure of t...

Embodiment 2

[0046] This embodiment is the process of making a three-dimensional tomographic specimen, such as Figure 4 As shown, the three-dimensional tomographic specimen is a human internal organ—heart, so it is shown as figure 2 As shown, the implementation method of making a three-dimensional tomographic specimen is as follows:

[0047] Step 1: Make a digital picture of the stereotomographic specimen

[0048] To select or draw a three-dimensional tomographic specimen based on Psdto3D, a total of seven 3D digital pictures are required to fully display its structure, which is consistent with the real object. The first six 3D digital pictures reflect views from different angles, and the seventh 3D digital picture is a three-dimensional The three-dimensional diagram of the tomographic specimen, in this embodiment, the three-dimensional diagram is the three-dimensional diagram of the heart, and the combination of the seven photos can completely reflect the structure of the entire three-...

Embodiment 3

[0058] The difference from Example 2 is that in the third step in this example, according to the actual needs of teaching, the thickness is selected and the quantity is determined. By making more than 20 planar tomographic specimens and overlapping them, a whole three-dimensional tomographic specimen is formed to complete the three-dimensional tomographic specimen. Fabrication of tomographic specimens.

Abstract

The invention discloses a method for manufacturing an imitative sectional imaging specimen and belongs to the field of medical teaching. The method comprises the following steps of: selecting or manufacturing a digital image of a sectional specimen; selecting a matrix material of the sectional specimen, wherein the matrix material is a transparent semi-soft plastic material or / and a grating material; and finally, manufacturing the selected matrix material into a planar sectional specimen or a three-dimensional sectional specimen according to the digital image. Due to the steps, the defects that the post production process is complicated, the manufacturing time is long and the efficiency is low because the material source of the sectional specimen is limited in the prior art are overcome, manpower and material resources are saved under the condition that the implementation mode is simple, and the imitative sectional imaging specimen is high in quality and suitable for popularization and application, can be saved for a long time and completely meets the requirements in clinical, teaching and scientific research applications.

Description

technical field [0001] The invention relates to a preparation method of a specimen, in particular to a preparation method of a simulated tomographic image specimen. Background technique [0002] Tomographic specimens are necessary experimental teaching specimens for medical and imaging teaching. Existing tomographic specimens are made of human corpses, frozen and fixed after perfusion, cut with tools such as sawing machine or planer, and then repaired, washed, antiseptic, fixed, encapsulated, etc. to obtain conventional tomographic specimens , plasticized fault specimens, etc. [0003] However, the sources of materials for such fault specimens mainly include death row prisoners and people who voluntarily donate their bodies, so their sources are very limited. At the same time, the post-production project of fault specimens has high requirements on the quality of personnel. The work intensity of production is high, the production time is long, and the efficiency is low. C...
