Example Embodiment

[0038] Example 1

[0039] A tomographic imaging device for biological specimens, such as figure 1 As shown, it includes a feeding module, a cutting module, a camera module, a controller, and a computer. The cutting module and the camera module are all connected to the controller, the feeding module is connected to the cutting module, and the control module is connected to the computer;

[0040] The feeding module is used to transport the biological specimens to be cut and control the transportation speed; in order to control the size of the cut specimens; the cutting module is used to cut biological specimens with infrared cutting assistance; the purpose is to obtain the thinnest tomographic specimens. The camera module is used to photograph the section of the cut biological specimen; the controller is used to control the size of the biological specimen cut by the cutting module, and control the camera module to photograph the cut specimen, and save the taken picture to a storage de...

Example Embodiment

[0044] Example 2

[0045] The working method of the biological specimen tomography imaging device described in embodiment 1, such as Figure 4 As shown, the specific steps include:

[0046] (1) Specimen processing: fill and wrap the specimen with plaster to make a cuboid. It is convenient for subsequent uniform cutting, shooting of the cut surface and computer data processing. Cuboid specimens are designed to facilitate clamping and cutting. The images taken by the camera are generally rectangular pictures, and the three-dimensional cross-section is designed to facilitate imaging.

[0047] (2) The controller determines the cutting length of the biological specimen through the infrared module, and calculates the cutting time, including the following steps:

[0048] A. Using infrared ranging method, according to the difference between the emission time and the receiving time, the cutting length s of the biological specimen is calculated by the formula (I), and the formula (I) is as fo...

Abstract

The invention relates to a biological specimen tomography cutting and imaging device and the working method thereof. The device comprises a material feeding module, a cutting module, a camera module, a controller and a computer wherein the cutting module and the camera module are both connected with the controller, the material feeding module is connected with the cutting module, and the control module is connected with the computer. The material feeding module is used to transport the biological specimen in need of cutting and controls the transportation speed; the cutting module is used to cut the biological specimen aided by infrared rays; the camera module is used to photograph the cut tomography of the biological specimen; the controller is used to control the size of the cut biological specimen, to control the camera module to photograph the cut specimen and to save the photographed images in a storage device; and the computer conducts three-dimensional reconstruction to the cut biological specimen. According to the method of the invention, through the technology of using the thinnest possible cutters, the biological specimen could be reconstructed in three dimensions by a computer so that a three-dimensional model for the biological specimen could be obtained accurately.

Description

technical field [0001] The invention relates to a biological sample tomography imaging device and a working method thereof, belonging to the technical field of biomedicine. Background technique [0002] In fields such as biomedicine, three-dimensional models of small organisms are often used. In order to obtain three-dimensional models accurately, three-dimensional restoration technology can be used to recover the more accurate three-dimensional models of organisms from cross-sectional photos for scientific research or teaching. [0003] As a research method, tomographic imaging was applied to human body anatomy as early as the 16th century, most of which used the cryosection method. With the development of science and technology, ultrasonic imaging, X-ray computed tomography, magnetic resonance imaging and other methods appeared in the 20th century to further develop human body tomography. Most of these research methods are tomographic imaging of the human body. However, t...
