摘要: For position sensors, e.g., a fiber-based system, that build a shape of an elongated member, such as a catheter, using a sequence of small orientation measurements, a small error in orientation at the proximal end of the sensor will cause large error in position at distal points on the fiber. Exemplary methods and systems are disclosed, which may provide full or partial registration along the length of the sensor to reduce the influence of the measurement error. Additional examples are directed to applying selective filtering at a proximal end of the elongated member to provide a more stable base for distal measurements and thereby reducing the influence of measurement errors.

摘要: Certain aspects relate to systems and techniques for compensating for compression in elongated shafts of medical instruments. Medical instruments can include elongated shafts that may experience compression when articulated. The medical instruments can be attached to instrument positioning devices that are configured to move the medical instruments to compensate for this compression. For example, an instrument positioning device can advance a medical instrument to compensate for compression in an elongated shaft of the medical instrument. In some instances, the amount of compression is determined using a compression compensation parameter. The compression compensation parameter can be determined during a calibration process of the medical instrument.
