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.

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...
