Abstract

We describe recent CT imaging work at Gemini. We focus on aspects of the scanning and reconstruction pro- cesses that are needed to deal with the poor repeatability of current laser-driven X-ray sources. In particular, we describe golden ratio scanning, a useful technique em- ployed with sources of degrading quality, and a custom beam profile correction step, applied to correct for the pulse-to-pulse changes in the X-ray beam profile and di- rection.
