Abstract
A system and method of treating an affected region of diseased tissue in a patient is described. A plurality of first radioactive seeds and a plurality of second radioactive seeds are implanted in the affected region. The first radioactive seeds each have one or more X-ray detectable markers providing a first X-ray detectable signature and the second radioactive seeds have one or more X-ray detectable markers providing a second X-ray detectable signature. An X-ray image of the affected region, including the first and second radioactive seeds implanted therein, provides representations of the first and second X-ray signatures which are visibly distinguishable. Representations of the first X-ray signature may then be associated with implanted seeds having a radioisotope source or dosage of the first radioactive seeds and representations of the second X-ray signature may then be associated with implanted seeds having a radioisotope source or dosage of the second radioactive seeds.
