  • Method for analyzing amount of activity
    Patent number: 6595908
    Abstract: A modular device for implanting radioactive seeds in an animal body through needles implanted in the body. Trains of radioactive seeds and non-radioactive spacers are assembled in an assembly unit. The assembly unit comprises a device for determining activity of the seeds with an accuracy that allows distinguishing between different activities within tolerance ranges of specified nominal activities for the seeds. After implantation of the seeds in the body a pre-plan may be recalculated taking into consideration actual activities of seeds implanted. Not correctly composed trains may be disposed of. A post-plan may be determined based upon actually measured activities of implanted seeds.
