Stop-action cardiac computed tomography.
Computed tomographic (CT) cardiac imaging in vivo has been hampered by motion of the heart during its cardiac cycle. A technique of post data-acquisition correlation of the angular projection data using the electrocardiogram as a reference signal is described. This method produced seven "stop action" images of the heart and resulted in delineating morphological detail not recognizable on the conventional CT scan.
