| 1. A method for associating EKG waveform data with computed tomography image data using a data synchronization scheme comprising:
generating the EKG wave form data using an electrocardiogram device;
operating a computed tomography imaging system so as to create the computed tomography image data;
communicating an exposure marker-in signal to said electrocardiogram device such that said exposure marker-in signal is associated
with the EKG waveform data; and
processing the computed tomography image data, the EKG waveform data and said exposure marker-in signal, so as to correlate
the EKG waveform data with the computed tomography image data.
