title: Wide-field transesophageal echocardiographic tomography: feasibility study.
abstract: In this report, we describe our initial investigation of wide-field ultrasonic cardiothoracic tomography utilizing a transesophageal transducer. Examination included manual rotation of an esophageal transducer 180 to 360 degrees in order to visualize contiguous related structures. Consecutive sector views were photographed and then incorporated into a digital graphics computer for smoothing. This feasibility study introduces the concept of wide-field transesophageal cardiothoracic ultrasound tomography, which holds promise for tomographic depiction of cardiothoracic and mediastinal anatomy.
