Abstract

In a method and apparatus for three-dimensional imaging of a moving examination subject, particularly heart imaging with an examination apparatus having at least one C-arm with a radiation source and a radiation receiver, the C-arm rotates around the examination subject at least once through 180° plus the radiation fan angle during the time span in which a contrast agent is in the examination subject for the registration of the two-dimensional projection images, on the basis of which a three-dimensional image reconstruction ensues.
