Claim 6:
7. An intravascular data analysis system to assess a blood vessel comprising:
an interface system configured to receive intravascular pressure data including a plurality of distal pressure (Pd) values measured by an intravascular data collection probe and a plurality of proximal pressure (Pa) values during a pullback of the intravascular data collection probe through the blood vessel;
a display system;
one or more memory storage devices comprising instructions; and
a processor in communication with the interface system, the display system, and the one or more memory storage devices, wherein the processor is configured to execute the instructions to:
determine a plurality of sets of Pd/Pa ratios based on the plurality of distal pressure (Pd) values and the plurality of proximal pressure (Pa) values, wherein each of the plurality of sets of Pd/Pa ratios includes Pd/Pa ratios that are determined through an entirety of one heart cycle,
determine a plurality of minimum Pd/Pa ratios, wherein each of the minimum Pd/Pa ratios is a minimum within one of the sets of Pd/Pa ratios over the entirety of the corresponding heart cycle, and
control the display system to generate a plot of a moving average of the plurality of minimum Pd/Pa ratios over time during the pullback.
