Abstract

To develop volumetric micro-CT fluoroscopy for small animal imaging, we have proposed a cone-beam system with multiple x-ray sources. In this paper, we extend Parker's single-source half-scan weighting scheme to the case of an odd number of x-ray sources that are equiangularly distributed, and apply it for half-scan Feldkamp-type reconstruction in this unique geometry. Inthe numerical simulation with the Shepp-Logan phantom, representative images indicate that the proposed half-scan Feldkamp-type algorithm produces temporal resolution significantly superior to that with a single x-ray sourcecone-beam system.
