Abstract: A computer-implemented method for simultaneously analyzing antegrade and retrograde blood flow is provided. The method is implemented using a computing device including a processor in communication with a memory. The method includes receiving a first plot of blood velocities over time and determining a first amount of blood flow based on the first plot. The first amount is associated with antegrade blood flow. The method additionally includes determining a second amount of blood flow based on the first plot. The second amount is associated with retrograde blood flow. Additionally, the method includes determining a mean amount of blood flow based at least in part on the first amount of blood flow and the second amount of blood flow, and storing at least one of the first amount, the second amount, and the mean amount of blood flow in the memory.
