Abstract:
An image-guided method for implanting radiation seeds into target tissue comprising the steps of:(a) imaging the target tissue using an imaging system, the imaging system having a image coordinate system;(b) using images of the target tissue from the imaging system, creating a treatment plan for the target tissue;(c) in accordance with the created treatment plan, loading a needle with radiation seeds and placing the needle with respect to the target tissue to initiate implantation;during implantation:(d) acquiring radiographic, geometric and dosimetric feedback on the placement of the needle with respect to the target tissue;(e) modifying the created treatment plan based upon the acquired radiographic, geometric and dosimetric feedback, said modifying producing a modified treatment plan; and(f) placing the radiation seeds from the needle into the target tissue at a position relative to the needle and acceptable according to the modified treatment plan.
