Claim 0:
1. A method of determining one or more diagnostic metrics to assess a blood vessel using intravascular data comprising:
sampling a sensor of an intravascular data collection probe disposed in the blood vessel at a sampling rate during a pullback of the intravascular data collection probe through the blood vessel to obtain a plurality of sampled distal pressure (Pd) values;
receiving, at an intravascular data processing system, the plurality of sampled distal pressure (Pd) values and a plurality of proximal pressure (Pa) values;
determining, using the intravascular data processing system, a plurality of sets of Pd/Pa ratios based on the plurality of sampled 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;
determining, using the intravascular data processing system, 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
controlling a display system to generate a plot of a moving average of the plurality of minimum Pd/Pa ratios over time during the pullback.
