Patent ID: 6905468

Claim:
A system for abdominal aortic aneurysm evaluation and monitoring, comprising: a hand-held data collection device which includes a plurality of separate ultrasound sources for obtaining three-dimensional ultrasound scan information of a selected portion of an abdominal aorta, each ultrasound source producing a three-dimensional scan, comprising a plurality of scan line planes, the three-dimensional scans arranged so as to overlap each other along the selected portion of the aorta; a processor for converting the scan line plane information obtained by the plurality of ultrasound sources to coordinates in which the converted scan line planes slice approximately perpendicularly through the aorta; a processor for determining aorta boundary information from the converted scan information; and a calculation circuit for calculating the diameter of the aorta from the boundary information, wherein diameter information of the aorta at a plurality of locations therealong is useful in determining the existence of an aneurysm in the abdominal aorta artery.
