High-resolution 3D X-ray tomography
Making SEM accessible for anyone, everywhere
Computed tomography or CT is a non-destructive imaging modality that provides much more than non-destructive testing (NDT) of materials and components. With CT, highly detailed 2D and 3D images can be generated of components that provide valuable information about their internal structures.
CT can reveal things like density, voids, pores, cracks, inclusions and other internal defects that have the potential to lead to premature or catastrophic service failure. Even better, 3D data is quantifiable and can be used with mathematical and structural models to perform finite element analysis, for example, or as a metrology tool.
As x-rays pass through the sample, differences in density and structure cause changes in the absorption of the
By combining data from hundreds or even thousands of images at different angles, the data is reconstructed into a 3D solid. This way, the sample can be scanned from the outside and inside.
With 2D digital graphics, we often refer to its dimensions in terms of pixels, with a pixel being the smallest individual definable element. In computer-generated 3D representations, the smallest element is a voxel, which can be compared to a 3D pixel or a combination of volume and pixel.
In industrial systems for larger parts, a typical voxel size of 50 µm to 200 µm can be used on samples such as automobile gearboxes. These resolutions can be improved by using MICRO CT with custom hardware to achieve submicron micro CT voxel resolutions.
TESCAN has high-resolution computed tomography within a new category, as it is large-format, high-resolution X-ray computed tomography equipment, which can scan an event very quickly, we are talking about 4D computed tomography.
These systems, like TESCAN DynaTOM, can scan very quickly, so quickly that they can capture dynamic events.
This allows changes in structure to be observed in real time, so that experiments can be carried out in situ and the behavior of materials can be observed as a function of changes in environmental conditions, e.g. heat, load, etc.
For example, we can follow the process of foam collapsing in a glass of beer.
TESCAN has three 4D micro CT models.
