Patent

CA 2612603

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.

L'invention porte sur un procédé de réglage de l'étalonnage d'un dispositif à ultrasons traçable utilisant la différence mesurée entre deux ensembles de repères de marquage des positions relatives d'un dispositif de suivi et de la tête de balayage du dispositif. L'invention porte également sur un dispositif à ultrasons traçable qui permet la fixation répétitive d'un suiveur à la tête de balayage et de conserver l'étalonnage initial entre le suiveur et la tête de balayage. L'invention porte en outre sur un dispositif d'étalonnage pouvant fixer répétitivement fixer un suiveur à une tête de balayage à ultrasons ou mesurer la différence entre les positions relatives du suiveur et de la tête de balayage.
