A CT scan (also called a CAT scan) is a series of cross-sectional X-ray images of the body. Learn why a CT scan is performed and what to expect during one.

The image series shows cross-sectional electron micrographs of individual nerve fibers in MS brain biopsies. Axons sheathed with myelin (black rings) can be seen, showing increasingly severe ...

Optical coherence tomography (OCT) is a type of noninvasive imaging test. Ophthalmologists use OCT to create high-resolution, cross-sectional images of the inside of a person’s eye. OCT can help ...

A cross-section image is obtained by taking adjacent scans of the object; this is also known as axial TD-OCT. Another method of performing TD-OCT is en face OCT, ...

Figure 1: Cross-sectional TEM of graphene–hBN heterostructures. In conclusion, our high-resolution images show that new kinds of heterostructures with atomically sharp interfaces can be ...

A computed tomography (CT) scan is a type of X-ray that shows cross-sectional images of a specific area on your body. For example, a CT scan of your knee would help doctors diagnose disease or ...

But researchers quickly adapted the technology to take cross-sectional images, or slices, at various points along the body. Then, in the early 1990s, ...
