Fast frame rate 2D cardiac deformation imaging based on RF data: What do we gain?

Fast acquisition sequences enable >200Hz 2D cardiac B-mode imaging with little compromise in image quality. Fast imaging minimizes frame to frame decorrelation, enabling radiofrequency (RF)-based tracking for enhanced signal-to-noise ratio (SNR) in motion and deformation imaging. Our objective was to compare the performance and clinical usefulness of Fast RF-based Tracking (FRFT) to the established modalities Tissue Doppler Imaging (TDI) and image-based speckle tracking (ST).
