  • Patent number: 11931116
    Abstract: A method for guiding resection of local tissue from a patient includes generating at least one image of the patient, automatically determining a plurality of surgical guidance cues indicating three-dimensional spatial properties associated with the local tissue, and generating a visualization of the surgical guidance cues relative to the surface. A system for generating surgical guidance cues for resection of a local tissue from a patient includes a location module for processing at least one image of the patient to determine three-dimensional spatial properties of the local tissue, and a surgical cue generator for generating the surgical guidance cues based upon the three-dimensional spatial properties. A patient-specific locator form for guiding resection of local tissue from a patient includes a locator form surface matching surface of the patient, and a plurality of features indicating a plurality of surgical guidance cues, respectively.

  • Publication number: 20140044333
    Abstract: A registration framework is presented that registers volumetric breast images captured before surgery with intraoperative surface images. The framework may be implemented using either image-based or model-based registration techniques. The method contains the steps of: identifying an air/tissue boundary from a volumetric image created at a first time; processing the volumetric image with an image filter to emphasize the air/tissue boundary; and registering a surface optically scanned image, with the filtered volumetric image, where the surface optically scanned image is created at a second time.
