  • Patent number: 10182873
    Abstract: A teleoperational medical system for performing a medical procedure in a surgical field includes a teleoperational assembly having a plurality of motorized surgical arms configured to assist in a surgical procedure. The motorized surgical arms have a motion limit defining a boundary beyond which the surgical arm cannot pass when the surgical arm is attached to a patient. The teleoperational medical system also includes a control system having a surgical threshold limit stored therein. The surgical threshold limit is an edge of a boundary to be potentially travelled by the surgical arm to suitably perform a surgical procedure. The control system is configured to compare the motion limit to the surgical threshold limit and notify an operator via an output device when the threshold limit is outside a range of motion bounded by the motion limit.

  • Patent number: 9230473
    Abstract: A head-mounted display (HMD) device is provided with reduced motion blur by reducing row duty cycle for an organic light-emitting diode (LED) panel as a function of a detected movement of a user's head. Further, a panel duty cycle of the panel is increased in concert with the decrease in the row duty cycle to maintain a constant brightness. The technique is applicable, e.g., to scenarios in which an augmented reality image is displayed in a specific location in world coordinates. A sensor such as an accelerometer or gyroscope can be used to obtain an angular velocity of a user's head. The angular velocity indicates a number of pixels subtended in a frame period according to an angular resolution of the LED panel. The duty cycles can be set, e.g., once per frame, based on the angular velocity or the number of pixels subtended in a frame period.

  • Patent number: 8758263
    Abstract: A system and a method of performing a frameless image-guided biopsy uses imaging, a six-dimensional robotic couch system, a laser guidance system, an optical distance indicator, and a needle control apparatus. A planning CT scan is made of the patient with stereotactic fiduciary markers to localize and produce digitally reconstructed radiographs. Two stereoscopic images are generated using an imaging device to visualize and identify a target tumor. The images are fused with the digitally reconstructed radiographs of the planning CT scan to process tumor location. The tumor location data are communicated to the movable robotic couch to position the target tumor of the patient at a known isocenter location. A biopsy needle is guided with a laser alignment mechanism towards the isocenter at the determined depth using a needle positioning apparatus and an Optical Distance Indicator, and a biopsy sample of the target tumor is obtained.

    Abstract: Apparatus associated with improved magnetic resonance imaging (MRI) guided needle biopsy procedures (e.g., breast needle biopsy) are described. One example apparatus includes a support structure configured to support a patient in a face-down prone position where a breast of the patient is positioned in a first free hanging pre-imaging position. The example apparatus includes an immobilization structure configured to reposition the breast into an immobilized position suitable for MRI and for medical instrument access. The immobilization structure may include a biopsy plate, a pressure plate, and MRI coils. The MRI coils are configured to be repositioned from a first position associated with the free hanging pre-imaging position to a second position associated with the immobilized position to facilitate improving the signal to noise ratio associated with signal received from the breast through the MRI coils. The biopsy plate is removable without removing either of the MRI coils.
