Recently, not only conventional two-dimensional (2D) image but also real time three-dimensional (3D) image is used for echocardiographic diagnosis. It has become possible to acquire and to display the image of the heart by using 3D electronic scan in real time. Also, echocardiography is increasingly used as a tool for analysis of cardiac function and as an aid to assessment of ischemia, dyssynchrony, heart failure and other cardiac conditions. Especially myocardial strain is getting a lot of attention as a promising parameter for this purpose. Myocardial strain is obtained by pattern matching process to track regional motion of myocardium with using ultrasound cine data also commonly known as speckle tracking. We developed 3D Wall Motion Tracking (WMT) for a 3D image data as well as developed 2D WMT for a 2D image data, and these applications have been provided on Artida TM as speckle tracking analysis. In this presentation, features and definition of some wall motion parameters based on WMT are explained. Also, some results of validation and clinical study with using WMT are reported. Finally, the latest technology about WMT is presented.
