Abstract
Several methods have been proposed to estimate myocardial motion from those based on the prior extraction of the tagging pattern to methods based on spatial phases [1]. Among several, the HARP method is one of the most popular methods of the latter group. Recently, an alternative method has been proposed: SinMod. It is however very difficult to objectively compare the accuracy of the methods.

Several methods have been proposed to estimate myocardial motion from those based on the prior extraction of the tagging pattern to methods based on spatial phases [1]
The objective of this paper is to propose a methodology to evaluate concurrently methods for estimating motion displacement fields from 2D tagged-MR image sequences
With the thickening sequence, mean magnitude error is less than 0.5 pixels for all the phases
