What Is a Micro CT Scan?

MicroCT usually uses a cone beam. Using a cone beam can not only obtain a true isotropic volume image, improve spatial resolution, and improve ray utilization, but also be much faster than the sector beam CT when acquiring the same 3D image.

Micro-CT

It uses a microfocus X-ray tube different from ordinary clinical CT, with a resolution of up to a few microns, second only to the level of simultaneous accelerated X-ray imaging equipment, and has a good "microscopic" effect. The price of high resolution is that the volume of the scanned sample is very small, only a few centimeters, which reflects its "mini" side.

MicroCT can provide 2 types of basic information: geometric information and structural information. The former includes the sample size, volume, and spatial coordinates of each point, and the latter includes material information such as the attenuation value, density, and porosity of the sample. In addition, SCANCO's finite element analysis function can also provide mechanical parameters such as the elastic modulus and Poisson's ratio of the tested material, analyze the stress and strain of the sample, and perform non- ^[1] destructive mechanical tests.
