  • Patent number: 10993678
    Abstract: A system for providing visual three dimensional assistance to a user during a medical procedure involving a soft organ. The system and method provide visual assistance to a user during a medical procedure involving a soft organ. The system and method utilize a processor for generating an image of the soft organ, a surgical instrument tracker for tracking a surgical instrument during the medical procedure, and a display in communication with the processor and the surgical instrument tracker for visually displaying in three dimensions, the image of the soft organ and the surgical instrument in relation to the soft organ.
    Type: Grant

  • Patent number: 9280822
    Abstract: A procedure for image segmentation on three-dimensional (3D) medical images, and a system, apparatus, and computer program that operate in accordance with the procedure. The procedure includes generating a projection including an anatomic structure, tracing a curve corresponding to the anatomic structure, extracting a curved volume of interest based on the curve and the projection, and extracting a segmentation of the anatomic structure. Also provided is a procedure for aligning anatomic structures in images, and a system, apparatus, and computer program that operate in accordance with the procedure. The procedure includes determining part of a biliary system in a first image, determining part of a hepatic portal vein or a hepatic artery in a second image, determining a gallbladder in the images, determining a cost function, and aligning the biliary system and the hepatic portal vein or hepatic artery by maximizing the cost function.

  • Patent number: 9099015
    Abstract: A procedure for pre-operating assessment of one or more anatomical structures generated from medical images and provided in a rendered 3D space, and an imaging system, apparatus, and computer program, that operate in accordance with the procedure. The procedure comprises providing one or more safety margin indicators in the rendered 3D space, each having a shape corresponding to that of a respective one of the anatomical structures within an organ and having a predetermined size of safety margin from the respective one of the anatomical structures. The procedure also comprises manipulating at least one of the shape and predetermined size of safety margin of at least one of the safety margin indicators in the rendered 3D space, and immediately providing a rendering in the 3D space of a manipulated version of the at least one safety margin indicator. Also provided is a procedure for defining at least one cutting surface to resect one or more medical anatomical structures using an imaging system.
