  • Computer-aided detection (CAD) of intracranial aneurysms
    Patent number: 9349176
    Abstract: A computer-aided system identifies aneurysm suspects in 3D image datasets. The system takes the raw image dataset as input and assigns one or more points of interest (POIs) in the image data. The system determines one or more features for each POI and identifies one or more aneurysm suspects from among the assigned POIs based on the determined features.
    Type: Grant
    Filed: July 15, 2010
    Date of Patent: May 24, 2016
    Assignee: Mayo Foundation for Medical Education and Research
    Inventors: Xiaojiang Yang, Bradley J. Erickson, Daniel J. Blezek, David F. Kallmes
  • Automated vascular region separation in medical imaging
    Patent number: 9042611
    Abstract: A system and/or method automatically identifies one or more vascular regions in a medical image or set of medical images. For example, the system/method may automatically identify vascular structures as belonging to the left carotid, right carotid, and/or basilar vascular regions in the head. The system/method takes as input the medical image(s) and automatically identifies one or more vascular regions. The system/method may also automatically generate MIP renderings of the identified region or regions.

  • INTERACTIVE PLANNING TOOL AND SIMULATION SYSTEM FOR CRYOABLATION SURGERY
    Publication number: 20110191082
    Abstract: A cryoablation procedure at a surgery site is planned and simulated. One or more pre-procedure planning images of the surgery site are displayed on a user interface. Positioning of one or more virtual cryoprobes relative to the one or more pre-procedure planning images on the user interface is facilitated. Properties of the one or more virtual cryoprobes are selectable. Ice ball formation at the surgery site is then simulated based on the position and properties of the virtual cryoprobes. The simulated ice ball formation is based at least in part on tissue properties of the surgery site at each image unit of the one or more pre-procedure planning images. Boundaries of the simulated ice ball formation on the one or more pre-procedure planning images are then displayed.
