1. A method for localizing and characterizing both the architectural features and function of cardiovascular tissues, comprising the steps of obtaining ECG data for the heart; processing the ECG data to localize, image, and characterize architectural features and function of tissues without use of other measuring devices or invasive procedures, the processing including inputting N-dimensional ECG data to a modified moving average filter to filter the N-dimensional ECG data and performing a phase space transformation process on the filtered N-dimensional ECG data in which a dynamically rich system is synchronized with a physiological signal; and using phase information to determine a location of an architectural feature or function of the tissues to display an abnormality associated with the tissues in a 3-D image.
