  • Publication number: 20200164230
    Abstract: Described herein are multi-leaf collimators that comprise leaf drive mechanisms. The leaf drive mechanisms can be used in binary multi-leaf collimators used in emission-guided radiation therapy. One variation of a multi-leaf collimator comprises a pneumatics-based leaf drive mechanism. Another variation of a multi-leaf collimator comprises a spring-based leaf drive mechanism having a spring resonator.

  • Patent number: 10646297
    Abstract: Robotic and/or surgical devices, systems, and methods include a manipulator configured to be mounted to a cannula and a processor. The processor is configured to detect a mounting state of the cannula, detect an input indicating the system is to be in a set-up mode, and inhibit transition of the system to the set-up mode in response to the detected mounting state. In some embodiments, detecting the input indicating the system is to be in the set-up mode includes detecting an activation of a dedicated input button. In some embodiments, detecting the input indicating the system is to be in the set-up mode comprises detecting a joint operation of a first kinematic structure coupling the manipulator with a platform that is supported by a second kinematic structure.

  • Patent number: 10555775
    Abstract: Methods and system perform tool tracking during minimally invasive robotic surgery. Tool states are determined using triangulation techniques or a Bayesian filter from either or both non-endoscopically derived and endoscopically derived tool state information, or from either or both non-visually derived and visually derived tool state information. The non-endoscopically derived tool state information is derived from sensor data provided either by sensors associated with a mechanism for manipulating the tool, or sensors capable of detecting identifiable signals emanating or reflecting from the tool and indicative of its position, or external cameras viewing an end of the tool extending out of the body. The endoscopically derived tool state information is derived from image data provided by an endoscope inserted in the body so as to view the tool.

  • Publication number: 20190388169
    Abstract: To assist a surgeon performing a medical procedure, auxiliary images generally indicating internal details of an anatomic structure being treated are displayed and manipulated by the surgeon on a computer display screen to supplement primary images generally of an external view of the anatomic structure. A master input device controlling a robotic arm in a first mode may be switched by the surgeon to a second mode in order to function instead as a mouse-like pointing device to facilitate the surgeon performing such auxiliary information display and manipulation.

  • Publication number: 20190366049
    Abstract: A catheter may include an elongate body extending from a proximal end to a distal end and defining a lumen; a push member mechanically coupled to the proximal end of the elongate body; and a slidable push grip disposed about an outer perimeter of the push member. The slidable push grip is controllably engageable with the push member. When the slidable push grip is in an engaged state with the push member, the slidable push grip transmits an axial force to the push member to enable the push member to transmit the axial force to the elongate body. When the slidable push grip is in a disengaged state with the push member, the slidable push grip is movable axially in at least one direction along a length of the push member while transmitting substantially no axial force to the push member.

  • Publication number: 20190262630
    Abstract: This application relates to methods for delivering radiation to a positron-emitting target within a subject under continuous PET guidance. Instead of directing radiation at a collinear path along each detected positron line-of-response (LOR), the methods generally include detecting a pattern of LORs that intersect the target. In response to the pattern, radiation may be delivered along paths that are not necessarily collinear to any of the LORs. Methods for further modifying radiation delivery as well as the detected LOR population are also described.

  • Publication number: 20190213770
    Abstract: An operator telerobotically controls tools to perform a procedure on an object at a work site while viewing real-time images of the work site on a display. Tool information is provided in the operator's current gaze area on the display by rendering the tool information over the tool so as not to obscure objects being worked on at the time by the tool nor to require eyes of the user to refocus when looking at the tool information and the image of the tool on a stereo viewer.

  • Patent number: 9999476
    Abstract: Robotic and/or surgical devices, systems, and methods include kinematic linkage structures and associated control systems configured to facilitate preparation of the system for use. One or more kinematic linkage sub-systems may include joints that are actively driven, passive, or a mix of both, and may employ a set-up mode in which one or more of the joints are actively driven in response to manual articulation of one or more other joints of the kinematic chain. In an exemplary embodiment, the actively driven joints will move a platform structure that supports multiple manipulators in response to movement of one of the manipulators, facilitating and expediting the arrangement of the overall system by moving those multiple manipulators as a unit into alignment with the workspace. Manual independent positioning of the manipulator can be provided through passive set-up joint systems supporting the manipulators relative to the platform.

  • Publication number: 20180133518
    Abstract: Disclosed herein are radiation therapy systems and methods. These radiation therapy systems and methods are used for emission-guided radiation therapy, where gamma rays from markers or tracers that are localized to patient tumor regions are detected and used to direct radiation to the tumor. The radiation therapy systems described herein comprise a gantry comprising a rotatable ring coupled to a stationary frame via a rotating mechanism such that the rotatable ring rotates up to about 70 RPM, a radiation source (e.g., MV X-ray source) mounted on the rotatable ring, and one or more PET detectors mounted on the rotatable ring.

  • Patent number: 9893008
    Abstract: An electronic isolation device is formed on a monolithic substrate and includes a plurality of passive isolation components. The isolation components are formed in three metal levels. The first metal level is separated from the monolithic substrate by an inorganic PMD layer. The second metal level is separated from the first metal level by a layer of silicon dioxide. The third metal level is separated from the second metal level by at least 20 microns of polyimide or PBO. The isolation components include bondpads on the third metal level for connections to other devices. A dielectric layer is formed over the third metal level, exposing the bondpads. The isolation device contains no transistors.
