Multi-resolution radiograph alignment for motion correction in x-ray micro-tomography

Latham, Shane; Kingston, Andrew; Recur, Benoit; Myers, Glenn; Sheppard, Adrian


Achieving sub-micron resolution in lab-based micro-tomography is challenging due to the geometric instability of the imaging hardware (spot drift, stage precision, sample motion). These instabilities manifest themselves as a distortion or motion of the radiographs relative to the expected system geometry. When the hardware instabilities are small (several microns of absolute motion), the radiograph distortions are well approximated by shift and magnification of the image. In this paper we...[Show more]
