How is TEE (trans esophageal echocardiography) superior for detecting clots in the left atrium?

Echocardiogram is an ultrasound study of the heart. Trans esophageal echocardiography is superior to trans thoracic echocardiography in detecting clots in left atrium because left atrium is just in front of the esophagus and there is no interference by the air in the lungs which might cover the heart occasionally while imaging from the external surface of chest.

Moreover, as the distance is lesser, TEE probe can user higher frequency ultrasound imaging which gives better resolution of smaller structures. Higher frequency ultrasound has lower wavelength. The smaller the wavelength, better the resolution. But the attenuation of waves increases with distance and is more at smaller wavelengths. Hence smaller wavelengths cannot be used for larger distances.
