Abstract

A real time radiation treatment planning system for use in effecting radiation therapy of a pre-selected anatomical portion of an animal body. A processor is provided with a three-dimensional imaging algorithm and a three-dimensional image segmentation algorithm for at least the specific organs within the anatomical portion and the needles. The processor converts the image data into a three-dimensional image of the anatomical portion using at least one single or multi-objective anatomy based genetic optimization algorithm. The processor determines in real time the optimal number and position of the hollow needles, the position of the energy emitting source within each hollow needle and the dwell times of the energy emitting source at each position. For post planning purposes, the processor determines, based on three-dimensional image information in real time, the real needle positions and the dwell times of the energy emitting source for each position.
