Abstract (en)
[origin: WO0025673A1] A method of trans-esophageal magnetic resonance analysis of a patient, such as an animal or human, includes providing a non-loop antenna (84), such as a coil or solenoid coil. The non-loop antenna is received within a Levin-type gastric tube (62). The gastric tube which receives the non-loop antenna is inserted in the esophagus of the patient. A tuning, matching and de-coupling circuit (12) is electrically connected to a magnetic resonance imaging scanner (18). The magnetic resonance imaging scanner (18) is employed to provide magnetic resonance imaging or spectroscopic analysis of an intra-Thoracic structure, such as the aorta, of the patient.
