    摘要: A medical robotic system includes an entry guide with articulatable instruments extending out of its distal end, an entry guide manipulator providing controllable four degrees-of-freedom movement of the entry guide, and a controller configured to limit joint velocities in the entry guide manipulator so as to prevent movement of tips of the articulatable instruments from exceeding a maximum allowable linear velocity when the entry guide manipulator is being used to move the entry guide.

    摘要: A method of calibrating a robotic device, such as a cardiac catheter, includes oscillating the device on an actuation axis by applying an oscillation vector at an oscillation frequency. While oscillating, a location of the device is periodically measured to generate a plurality of location data points, which may express the location of the device relative to a plurality of measurement axes. The location data points are then processed using a signal processing algorithm, such as a Fourier transform algorithm, to derive a transfer function relating a position of the device to a movement vector for the actuation axis. The transfer function may be resolved into and expressed as a calibration vector for the actuation axis, which may include one or more components, including zero components, directed along each of the measurement axes. The process may be repeated for any actuation axes on which calibration is desired.

    摘要: A robotic catheter rotatable device cartridge may include a housing member attachable to a drive mechanism for rotating the cartridge and a catheter attached to the cartridge along an axial direction of the catheter. A slider block may be generally slidable relative to the housing and engaged with one or more steering wires for controlling movement of the catheter in a transverse direction relative to the axial direction. The catheter may include the steering wire(s) engaged therewith and movable in the transverse direction when the slider block is linearly driven in a predetermined direction.

    摘要: A fiducial marker system (210a-c) comprises a first unit and a second unit. The first unit is patient affixable and comprises a partly spherical inner surface having a first center point that is adapted to receive a touch probe measurement head for measuring the spatial position of the center point. The second unit is releasably attachable to an outer surface of the first unit, and has a second center point, wherein the first center point and the second center point are substantially identical when the second unit is attached to the first unit. For stereotactic therapy, a patient is imaged with the first and second unit assembled. Then the second unit is detached. A stereotactic frame (300) is attached to the first units via arms. Thus frameless imaging is provided in a frame based stereotactic surgery system with high precision. Repeated assembly of the frame (300) to the first units, remaining in the patient, provides advantageous fractionized stereotactic radiotherapy.

    摘要: The present invention relates to a system for guiding a medical instrument in a patient body. Such a system comprises means for acquiring a 2D X-ray image of said medical instrument, means for acquiring a 3D ultrasound data set of said medical instrument using an ultrasound probe, means for localizing said ultrasound probe in a referential of said X-ray acquisition means, means for selecting a region of interest around said medical instrument within the 3D ultrasound data set and means for generating a bimodal representation of said medical instrument detection by combining said 2D X-ray image and said 3D ultrasound data set. A bimodal representation is generated on the basis of the 2D X-ray image by replacing the X-ray intensity value of points belonging to said region of interest by the ultrasound intensity value of the corresponding point in the 3D ultrasound data set.
