  • Method and apparatus for removing tissue from a region of interest using stereotactic radiographic guidance
    Patent number: 6258104
    Abstract: A method and apparatus for removing tissue from a volume surrounding a region of interest with a body part of a patient is disclosed. The tissue removal volume and location is determined by stereotactic radiography. The size of the tissue removal volume surrounding the region of interest is derived by placing boundaries around the region of interest in each stereotactic radiographic image. A tissue removal tool is moved within the derived tissue removal volume. The tissue in the region of interest which has been previously diagnosed as cancerous can be marked with a radioactive isotope, for example, and the removal of such tissue from the removal volume which surrounds the region of interest can be monitored to determine whether the tissue in the region of interest has been completely removed.

  • Method and apparatus for displaying images
    Patent number: 6157373
    Abstract: A method and apparatus for displaying a digital image of at least a portion of an object displayed in a film transparency having object identifying indicia thereon is provided. The apparatus uses a position sensitive panel having a surface for supporting the film transparency and further having an output for providing an output signal corresponding to the two dimensional spatial position of a selected point of interest on the panel. The apparatus is further provided with an object identifying indicia reader having an output for providing an output signal corresponding to object identifying indicia on the film transparency. In one embodiment, a digital image of the object depicted on a film transparency can be displayed by simply touching the transparency which causes an associated computer controller to identify the transparency through the indicia thereon and recall corresponding digital image data.
