Abstract
Sequential cone-beam tomography is a method where data of two or more circular trajectories are used to reconstruct the object function. The authors propose a condition for the data acquisition that ensures that all object points between two successive circles are irradiated over an angular span of the X-ray source position of 360 degrees in total. A fast and efficient approximative reconstruction method for sequential cone-beam tomography is presented that is based on the tent-FDK method and can handle axially truncated projections
