Abstract

In this work, we investigate exact image reconstruction within a 3D region of interest from data acquired with a circle-arc trajectory. In particular, the data may contain both longitudinal and transverse truncations. This work may find applications in lung or heart imaging using a C-arm scanner. When the arc portion of the trajectory is posterior or anterior to the patient, exact images within the lung or heart region can be reconstructed from truncated data.
