1. A method for providing a two dimensional real time ultrasonic image of internal structures of the human body comprising the steps of:
- a. providing a probe having a first and a second end with a two dimensional real time ultrasonic transducer capable of producing two dimensional real time images at the first end thereof, with the second end of the probe including means for electrically connecting said transducer to an image display device which displays a two dimensional real time image when the two dimensional real time ultrasonic transducer is activated;
b. inserting the first end of the probe and the two dimensional real time ultrasonic transducer into the rectum of the body and then into the colon, said colon passing adjacent to the internal structure to be imaged, said structure being located outside of the colon;
c. visually guiding and advancing the first end of the probe through the colon into the transverse, descending, or ascending colon, and the first end of the probe is then manipulated to move the colon bringing the two dimensional real time ultrasonic transducer adjacent to the structure to be imaged, said structure being located outside of the colon; and
activating the two dimensional real time ultrasonic transducer to provide a moving, two dimensional real time image of the internal structure for viewing on the image display device.

Abstract
This invention is for a new device and method for 2 dimensional, real time ultrasonic imaging of deep internal organs and vascular structures. This device and method allows clear unattenuated images of these organs and vessel by placing a 2 dimensional, real time ultrasonic transducer immediately adjacent the organ or vessel by introduction of the transducer, on the end of probe, into either the colon or the esophogus. The transducer can then be positioned adjacent the organ or vessel of interest of imaging.

7. A method for determining the blood flow rate and direction in a particular blood vessel comprising the steps of:
-
a. providing a probe having a first and a second end with a Doppler two dimensional real time ultrasonic transducer capable of providing both Doppler interrogation and producing two dimensional real time images, located on the first end thereof, and the second end of the probe including means for electrically connecting said transducer to an image display device; b. inserting the first end of the probe and the Doppler two dimensional real time transducer into the rectum and then into the colon, where the colon passes adjacent to the vessel whose flow rate and direction is to be determined, said vessel being located outside of the colon; c. visually guiding and advancing the first end of the probe through the colon such that the Doppler two dimensional real time ultrasonic transducer is located adjacent the vessel whose flow rate and direction is to be determined; d. activating said Doppler two dimensional real time ultrasonic transducer and utilizing the two dimensional real time image produced to precisely place the transducer close to the vessel whose flow rate and direction is to be determined and then using Doppler interrogation to calculate the blood flow rate and direction of the selected vessel. - View Dependent Claims (8, 9, 10, 11, 12)
