Abstract
A method and apparatus for automatically measuring the circumference of a first region enclosed in a second region internal to a living organism, wherein the first and second regions consist of different cellular matter. One embodiment of the present invention includes generating a point inside an interior of the first region. A set of radial vectors are then generated, which emanate from the point in the interior of the first region. A path is then selected which intersects the set of radial vectors. The path is selected by identifying a distinguishable ultrasonic measurement along the respective radial vectors. A length of the selected path is then measured to generate the circumference of the first region.
