Key result
The coronary tree expert analyzer (CORTEX) was developed as a computer vision system to describe the bidimensional shape and position of coronary vessels in standard radiographic images.
The CORTEX computer vision system provides a hierarchical, algorithmic approach to automatically describe coronary vessel shape and position in standard angiographic images.

May enable automated coronary vessel analysis on angiograms; extends computer vision methods but leaves clinical validation open.
The coronary tree expert analyzer (CORTEX), a computer vision system for the description of the bidimensional shape and position of coronary vessels in standard nonsubtracted radiographic images, is described. The basic ideas used in developing the system are given, and the modules of CORTEX and their algorithmic implementation are described. According to a bottom-up approach, grouping criteria are utilized to produce intermediate image representations of increasing scale in a hierarchical manner (from edge points to curves, segments, bars, and finally to vessels and bifurcations). The evaluation of CORTEX performances according to a signal-detection-theory-like approach is also discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
