Abstract

Continuous acquisition is a scanning technique in which the object rotates without interruption while the x-ray projections are acquired. This results in a considerable reduction in scanning time, compared to a step-and-shoot acquisition. While a reduced scanning time is preferred, motion during acquisition leads to motion artifacts in the reconstructed image. Existing techniques that reduce these motion blurring artefacts assume a purely rotational motion with a constant angular velocity. We propose a technique with a generalized motion model that allows for a flexible incorporation of object motion. While it is also possible to model acceleration, this remained unvalidated. Based on simulated data, we demonstrate the applicability of this technique for scans in which the object rotationally accelerates.
