    摘要: A magnetic force control system for guiding a medical instrument within a body includes: a controlled magnet coupled to the medical instrument; a controller magnet that exerts a magnetic force on the controlled magnet; a magnetically permeable shield, placed between the controlled magnet and the controller magnet, that selectively modulates the magnetic force by rerouting magnetic field lines; and a control system. A method for guiding a medical instrument within a body with magnetic force control includes: providing a controlled magnet coupled to the medical instrument, inserting the controlled magnet and medical instrument into the body, providing a controller magnet outside the body, placing a magnetically permeable shield between the controlled magnet and the controller magnet, applying magnetic force, and selectively modulating the magnetic force with the shield to vary at least one of amplitude and orientation of the magnetic force, thereby guiding the controlled magnet within the body.

    摘要: Robotic instrument systems and control implementations are disclosed. In one such system, an elongate guide instrument such as a guide catheter includes tension or deflection element such as a stainless steel wire or pull wire. An actuator, such as a servo motor, is operably coupled to the controller. The controller is configured to control actuation of the servo motor based on execution of a control model including a mechanics model that accounts for a force on the guide instrument. The control model may also utilize both kinematics and mechanics models. The controller is configured to control actuation of the actuator based the control model that includes the mechanics model such that the elongate guide instrument bends when the actuator moves the deflection member.

    摘要: Mosaicing methods and devices are implementing in a variety of manners. One such method is implemented for generation of a continuous image representation of an area from multiple images consecutively received from an image sensor. A location of a currently received image is indicated relative to the image sensor. A position of a currently received image relative to a set of previously received images is indicated with reference to the indicated location. The currently received image is compared to the set of previously received images as a function of the indicated position. Responsive to the comparison, adjustment information is indicated relative to the indicated position. The currently received image is merged with the set of previously received images to generate data representing a new set of images.
