ABSTRACT:
A pre-computed sensitivity function providing ex ante assessment of optimal placement of a single radioactive seed, is used for sequential placement of multiple radioactive seeds. The location of each successive seed may also be constrained by an exclusion function omitting areas in the target receiving a pre-defined dose from the preexisting seeds. This technique makes possible optimization of additional dimensions of treatment planning including using a different number of needles and using mixed seed types.
