Self-calibrating helical micro-CT and computed tomography dimensional measurements

Varslot, Trond; Pyka, Grzegorz; Valterova, Eva; Young, Ben; Patakova, Zuzana

Abstract: We demonstrate how for helical micro-CT, the ability to perform dimensional measurements on an image is intimately linked to image sharpness. This leads to a systematic way to make statements about uncertainty in the absolute scale of a tomogram. We use this to computationally reduce the measurement error, and therefore ensure system accuracy in terms of sphere-distance measurements, as defined in VDI 2630.

Keywords: Tomographic imaging (2), geometric alignment (1), dimensional accuracy (1),
