The sampling geometry of CT-scanners plays an important role for the reconstruction process of the images. We have previously reported elsewhere a new system that can collect parallel sets of Radon data directly through appropriate collimation of the conventional fan-beam. These data can be efficiently treated with series expansion algorithms (for example, OPED), without significant loss of image quality. Preliminary results with a test device have shown the feasibility of the idea. In this contribution, we stress the potential of the idea showing results with an optimized set-up. At the end, we discuss two technical difficulties of the proposed system, which have motivated future work in our group.
