Resolution of a 3D X-Ray Microscope: Defining Meaningful Resolution Parameters

Although the definition of resolution may seem straightforward, several non-equivalent terms are used to represent the resolution capabilities of 3D tomographic instruments. ZEISS specifies spatial resolution, the most meaning ful measurement of a microscope’s performance. This Tech Note explains how to objectively evaluate the resolu tion performance of 3D X-ray microscopes (XRM) and other computed tomography (CT) instruments relevant to the user’s research and production goals.
