Cardiac strain quantification is important in the
assessment of regional myocardial function, and has many
different clinical applications. The current gold
standard for non-invasive myocardial strain measurement
is cardiac magnetic resonance (CMR) tagging. It is also
possible to estimate global and regional strain from
standard (non-tagged) steady-state free precession
(SSFP) cines using non-rigid registration , thereby
removing the need to acquire additional sequences. We
report an in-line implementation providing numerical
and graphical strain measurements without user
interaction as part of the standard SSFP acquisition.
