Abstract :
Double-gated in-vivo small animal cone-beam micro-CT scans provide five-dimensional information about the object: the three volume dimensions plus the temporal dimensions of the respiratory motion and the heart motion, respectively. Double gating is typically performed to separate respiratory from cardiac motion when imaging the animal´s lung or heart.
