Proposal of Transesophageal Echo Examination Support System by CT Imaging
Transesophageal echocardiography and CT imaging have been used to provide definite diagnoses of cardiac diseases, such as angina and myocardial infarction. Transesophageal echocardiography has been performed by manually adjusting probe depth and ultrasound irradiation angle while referring to the echo image. However, it is difficult to grasp the three-dimensional (3D) position of the heart with echo images alone. Moreover, this takes a long time and puts a heavy burden on patients and doctors. Therefore, we propose a new method in order to smoothly create a preoperative plan. The proposed method replaces conventional transesophageal echocardiography with CT images. The proposed system can inspect CT images interactively and with a shorter examination time. Moreover, unlike transesophageal echocardiography, there is no burden on the patient when using the proposed method.
