  • Apparatus and method for determining optimal locations to place radioactive seeds at a cancerous site
    Patent number: 6095975
    Abstract: An apparatus and method for determining optimal locations for placing radioactive seeds at a cancerous site. After a plurality of cross-sectional images of the cancerous site are obtained, a contour of an area on each cross-sectional image of the cancerous site is defined and transferred to a three-dimensional coordinate system. Then, a population of locations within each area of each cross-sectional image of the cancerous site where radioactive seeds can be placed is identified. A genetic algorithm is then implemented to determine the optimal number of locations within the cancerous site to place the radioactive seeds.
