  • Publication number: 20210121235
    Abstract: A method, system, medium, and implementations for computer-aided preoperative surgical planning are described. Input data acquired with respect to a part of a patient is received by the system. The part corresponds to an organ, e.g., lung, of the patient to be operated on and includes one or more lesions to be removed during an operation. Then, an anatomic 3D model of the part of the patient is generated. Based on the generated anatomic 3D model, a preoperative plan for linear-cutting stapler resection of the one or more lesions from the organ to be carried out during the operation is obtained. The stapler cartridge size and the staple length are estimated based on the preoperative plan. Further, the resection based on the preoperative plan is visualized.

  • Patent number: 10945793
    Abstract: The present teaching relates to surgical procedure assistance. In one example, a first image of a patient captured prior to a surgical procedure is received. A treatment plan is generated based on the first image. The treatment plan includes information related to one or more surgical instruments. A second image of the patient captured after the surgical procedure has been initiated is received. The treatment plan is dynamically adjusted based on a pose of any of the one or more surgical instruments identified from the second image. A third image of the patient captured after a lesion is treated by at least one of the surgical instruments based on the adjusted treatment plan is received. Whether a further treatment to the lesion is needed is determined based on the third image. Upon determining a further treatment is needed, an updated treatment plan is dynamically generated based on the third image.

  • Patent number: 10716626
    Abstract: The present teaching relates to interactive medical image processing for surgical procedure planning. In one example, a three dimensional (3D) image of a kidney is obtained. The three dimensional image is rendered on a display screen. An input is received from a user specifying a location with respect to a representation of the kidney in the rendered three dimensional image. A representation of an instrument is rendered on the display screen based on the location. The instrument is automatically aligned with an infundibulum pathway of calyx at the location with respect to the kidney. A graphical line extension is rendered on the display screen to visualize the alignment of the instrument. One or more measurements related to the kidney are determined based on the location and an anatomical structure of the kidney.

  • Patent number: 10307079
    Abstract: The present teaching relates to surgical procedure assistance. In one example, a first image of an organ having a lesion is obtained prior to a surgical procedure. Information related to a pose of a surgical instrument at a first location with respect to the lesion is received from a sensor coupled with the surgical instrument. A visual environment having the lesion and the surgical instrument rendered therein is generated based on the first image and the information received from the sensor. A second image of the organ is obtained when the surgical instrument is moved to a second location with respect to the lesion during the surgical procedure. The second image captures the lesion and the surgical instrument. The pose of the surgical instrument and the lesion rendered in the visual environment are adjusted based, at least in part, on the second image.

  • Patent number: 9984456
    Abstract: A method for labeling vessel branches forming first and second vessel systems. A 3D image is segmented to obtain vessel branches. First and second root points are then determined. Starting from the first root point, the vessel branches are traced to derive a tracing path and a break point is determined, that separates the tracing path into two portions. A region of interest in the 3D image is determined with respect to the break point, in which center lines are assigned to the first or second vessel system. A 3D cutting structure is generated based on distances measured from points on the center lines to the 3D cutting structure. Graph representations are constructed for the first and second vessel systems. The vessel branches are labeled with different labels based on the graph representations.

  • Publication number: 20170347988
    Abstract: Systems and methods relating to placement of an ultrasound transducer for a procedure. In a non-limiting embodiment, a 3D environment including images of a body region of a patient, as well as images including a first virtual representation of an ablation needle at a first location and a second virtual representation of an ultrasound transducer at a second location is rendered on a display device. A determination may be made as to whether the first and second virtual representations collide at a first collision point. If so, at least one parameter associated with an orientation and/or position of the second virtual representation may be adjusted. A determination may then be made as to whether or not the first and second virtual representations still collide and, in response to determining that there is no collision, position data indicating the location of the second virtual representation after the adjustment, is stored.
