A new way of exploring the regional function of the heart, speckle tracking, can analyze heart deformations along the principal axes of the heart. The advantage of this technique has been shown in various pathological situations. Currently, this technique is mostly used in longitudinal and transverse view 2D imposing multiple planes cuts. 3D potential of this technique is not currently known, acquisition of 3D technology is recent (2004) and dedicated software is confidential dissemination and unvalidated.
