VORRICHTUNG UND VERFAHREN FÜR EINEN VERFOLGBAREN ULTRASCHALL
摘要
The invention provides a method for adjusting the calibration of a tracked ultrasound device using the measured difference between two sets of fiducial markings in two relative positions of a tracker and an scan head of the device. The invention also provides a trackable ultrasound device that enables repeatable attachment of a tracker to a scan head, thus preserving an initial calibration between the tracker and the scan head. Furthermore, the invention provides a calibration jig that can be used to repeatably attach a tracker to an ultrasound scan head or to measure the difference between two relative positions of a tracker and a scan head.
