Abstract
In a method and apparatus for locating in a three dimensional data array an arcuate object having an axial extent, slices of data generally transverse to the axial extent of the object are selected. Rays generally radially of the arcuate object are selected within the slices. Crossing points where the rays cross the boundaries of the arcuate object are located. The position of the arcuate object is determined from the positions of the located points.
