COMPUTER AIDED TUBE AND TIP DETECTION

摘要

A computer aided tube and tip detection method for a radiographic image. Radiographic image data is obtained, and a region of interest in the image is determined. The image is processed to provide edge enhancements forming an edge-enhanced image. Edge segments in the edge-enhanced image are detected. Connected lines from the edge segments are formed to obtain a set of connected lines. A tube structure is identified by pairing one or more pairs of connected lines that are separated by a width dimension in a predetermined range. A tip is detected for the tube structure according to the convergence or divergence of paired connected lines.
