From: A direct comparison of natural and acoustic-radiation-force-induced cardiac mechanical waves
Effect of filter settings on wave visibility in M-panels of an active SWE sequence. (a) Various M-panels are displayed for different ARF pushes throughout the cardiac cycle, after applying a 75–750 Hz bandpass filter to the TDI data. (b) The same M-panels as in (a) are shown after applying a 15–100 Hz bandpass filter to the TDI Data, as done for natural SWE processing. Events of mitral and aortic valve closure (AVC and MVC) are denoted in their respective frames.
