In circular tagging, the information of tag lines which is used for strain imaging lies on an annular region in the k-space that can be collected efficiently through concentric sequence in shorter scan times. In this study, we investigate the feasibility of real-time data acquisition for strain imaging through the effective k-space concentric sampling. We showed that by acquisition of a small fraction of the k-space data (approximately 11%), we can still reconstruct the image in an effective way and extract the tag lines information required for strain analysis and this will be very promising for real-time strain imaging.
