Study on Coordinate Information Generation Method of Interested Area in IMRT Inverse Planning System
In inverse planning system of Intensity Modulated Radiation Therapy (IMRT), the coordinate of interested area (target, organ at risk) is the necessary information for optimization algorithm. This paper analyzes several classical region filling algorithms firstly. Based on the VTK toolkits, Bezier curve algorithm, and the improved Watershed algorithm, a method using interactive delineation tool to save the coordinate information of interested area is realized. The information in the delineated area is accurately extracted by the method.
