Figure 2From: A non-invasive clinical application of wave intensity analysis based on ultrahigh temporal resolution phase-contrast cardiovascular magnetic resonanceCalculation of wave speed. Samples of velocity (A) and area (B) curves calculated with the plug-in. These data are combined in a loop (C) whose linear slope in early systole (highlighted in red) yields wave speed c. Waveforms from both a volunteer (top row) and a patient (bottom row) are shown.Back to article page
