Fig. 4From: Cardiovascular magnetic resonance myocardial feature tracking using a non-rigid, elastic image registration algorithm: assessment of variability in a real-life clinical settingStrain curve examples from different subjects in the patient group. The continuous line represents the first acquisition, while the dashed line represent the second acquisition. Blue shows the result obtained by the Expert observer, red the result obtained with skilled observer and green the result achieved by the beginner. In order to ease the visualization, the absolute value of the longitudinal strain along the vertical long axis is usedBack to article page
