Outline of process to register the 3D ischemic, border, and remote crystal zones with 2D echocardiograms. The three transducer-mounted crystals provide a common reference in 3D coordinate space to aid registration of 3D echocardiograms and myocardial crystals (middle image). With appropriate registration, crystal zone locations can be projected onto 2D echocardiograms for regional strain analysis (right image)
