Techniques in helical scanning, dynamic imaging and image segmentation for improved quantitative analysis with x-ray micro-ct... In 2010 a new instrument was constructed that utilises theoretically-exact image reconstruction based on helical scanning trajectories, allowing higher cone angles and thus better utilisation of the available X-ray flux....
