ABSTRACT:
The present invention is a method and apparatus for ultrasound imaging of internal structures near a stomach of a patient. Under the present invention, high resolution images of abdominal structures may be obtained including, for example, the abdominal aorta, kidneys, the liver, superior mesenteric, both renal arteries, the hepatic arteries, the splenic artery, the vena cava, renal veins, portal vein, splenic and mesenteric veins. High resolution imaging of blood flow within blood vessels including those within organs may also be obtained. High-resolution imaging of these structures thereby obviates the need for otherwise invasive procedures. The imaging device of the present invention includes a probe having a head, a body and an end opposite the head. An ultrasonic transducer is coupled to the head of the probe and a gel material covers the ultrasonic transducer to enable a good contact with a stomach wall portion. The imaging device has a substantially rigid body through the use of a substantially rigid sheath or a sheath and a substantially rigid rod. The imaging device also includes a handle near the end of the probe for manipulating the location and positioning of the ultrasonic transducer to ultrasonically image the tissue and/or organ of interest.
