Pulse wave velocity determination using co-registration between intravascular data and extraluminal images, and associated systems, devices, and methods

A system includes processor circuitry configured to receive a set of intravascular data from an intravascular sensor at a first location within a blood vessel. The processor circuit simultaneously receives a set of cardiovascular data from a heart monitor. After the intravascular sensor is moved from the first position to a second position, the processor circuit receives an additional set of intravascular data from the intravascular sensor and receives an additional set of cardiovascular data from the heart monitor. The processor circuit then determines a distance between the first location and the second location, and determines a pulse wave velocity associated with blood flow within the blood vessel based on the intravascular data set, the cardiovascular data set, and the distance. The processor circuit then outputs the pulse wave velocity to a display. 一种系统包括处理器电路，所述处理器电路被配置为从血管内的第一位置处的血管内传感器接收一组血管内数据。所述处理器电路同时从心脏监测器接收一组心血管数据。在所述血管内传感器从所述第一位置移动到第二位置之后，所述处理器电路从所述血管内传感器接收额外的一组血管内数据并且从所述心脏监测器接收额外的一组心血管数据。然后，所
