Cardiac axis-oriented full-volume data acquisition in

Cardiac axis-oriented full-volume data acquisition in real-time three-dimensional transesophageal echocardiography to facilitate on-cart analysis.

We propose a useful method to acquire a full-volume dataset that allows for efficient assessment of cardiac structures by real-time 3-dimensional transesophageal echocardiography (3DTEE). In our method, bicommissural full-volume acquisition, the dataset is acquired with the X-Y-Z axes aligned along the lines connecting the mitral commissures, the mitral annular center to the left ventricular apex, and the mitral anterior-posterior ends, respectively. The image dataset obtained using this method not only allows for visualization of en face images of the cardiac structures, but box cropping of the dataset also provides useful sectional images that are the analogues of the standard 2DTEE views. Our method can potentially standardize 3D image orientation of the cardiac structures and facilitate intraoperative on-cart analysis in real-time 3DTEE.
