Transesophageal echocardiography

Transesophageal echocardiography (TEE) is a special exploration location and high-quality image display, which opens up a new window of cardiac large vessel imaging examination, expands the scope of transthoracic ultrasound examination, and makes up for the shortcomings of TEE. It is gradually widely used. Transesophageal ultrasound is divided into single-plane, double-plane, and multi-plane types. The frequency of the electronic phased array probe is 7-3.5MHz, among which color Doppler blood flow imaging is 5.0-3.5MHz, and spectral Doppler 3.5MHz. Adjustments are the same as transthoracic echocardiography.
