Abstract

Methods and systems of processing and displaying data that include obtaining and processing time-time data to obtain an in-phase sum of the time-time data, and of providing and utilizing the in-phase sum of the time-time data to generate a graphical display of the Radon sum of the time-time data. The in-phase sum of the time-time data may be provided for display, for example, by outputting a data signal suitable for generating a graphical representation of the in-phase sum of the time-time data, and the output data signal may be utilized to generate a graphical representation of the in-phase sum of the time-time data.
