1 and the preparation requirements of micro-ct
Sample preparation needs to ensure the smooth and uniform surface of the sample, and cut the sample into appropriate sizes according to the requirements of the scanner. In addition, the color, weight and size of the sample also need to be consistent with the scanning parameters of the micro-CT instrument to ensure the accuracy of the scanning data.
2. Installation requirements of micro-ct
Microscopic ct scanning process needs to be carried out after installation, so sample installation is very important. The sample needs to be placed in a miniature CT instrument, so that it can be scanned without being affected by external forces.
3. Debugging requirements of micro ct
Before debugging the micro CT instrument, it needs to be adjusted according to the scanning parameters to ensure the accuracy and reliability of the scanning data. In addition, in the process of scanning, it is necessary to continuously monitor the parameters of the instrument in order to find and solve the scanning problems in time.
Introduction of microcomputer principle
The principle of microcat is to use X-rays to penetrate the sample, and obtain the internal structure information of the sample through the absorption and scattering of X-rays. Micro-ct can be used to image various materials, including biological tissues, engineering materials, rocks and fossils.
Micro-ct adopts a micro-focus X-ray tube different from ordinary clinical CT, and its resolution is as high as several microns, which is second only to the level of synchronous accelerated X-ray imaging equipment, and it has a good "microscopic" principle. Cone beam can not only obtain a truly isotropic volume image, improve spatial resolution and improve ray utilization, but also obtain the same three-dimensional image much faster than fan beam CT.
