摘要

The invention relates to a real time radiation treatment planning system for use in effecting radiation therapy of a pre-selected anatomical portion of an animal body according to the preamble of claim 1. According to the invention said processing means are provided with a three-dimensional imaging algorithm and a three-dimensional image segmentation algorithm for at least the specific organs within said anatomical portion and the needles for converting the image data obtained with said imaging means into a three-dimensional image of the anatomical portion, whereby by using at least one single or multi-objective anatomy based genetic optimization algorithm for pre-planning or virtual simulation purposes said processing means are arranged to determine in real time the optimal number and position of at least one of said hollow needles, the position of said energy emitting source within each hollow needle as well as the dwell times of said energy emitting source at each position; whereas for post planning purposes said processing means are arranged to determine based on three-dimensional image information in real time the real needle positions and the dwell times of said energy emitting source for each position.
