Title
Adaptive zooming in X-ray computed tomography
Author
Abstract
In computed tomography (CT), the source-detector system commonly rotates around the object in a circular trajectory. However, such a trajectory does not allow to exploit a detector fully when scanning elongated objects. In this paper, a new approach is proposed, in which the full width of the detector is exploited for every projection angle. This approach is based on the use of prior information about the objects convex hull to move the source closer to the object, obtaining more detailed information from particular projection angles. Experiments show that this approach can significantly improve reconstruction quality.
