Abstract

Methods may be provided to operate an image-guided surgical system using imaging information for a 3-dimensional anatomical volume. A pose of a probe that defines a longitudinal axis may be detected based on information received from a tracking system. A placement of a virtual implant for the 3-dimensional anatomical volume may be determined based on the pose of the probe and based on an offset from an end of the probe along the longitudinal axis, such that a trajectory of the virtual implant is in alignment with the longitudinal axis of the probe in the pose. After determining the placement of the virtual implant, the virtual implant may be adjusted in response to movement of the probe while maintaining the trajectory of the virtual implant.
