1. A method for aligning or guiding a tracked instrument during an image-guided intervention, the method comprising:

  • registering volumetric image data of an anatomy of a patient to patient space data of the anatomy of the patient, wherein the patient space data is obtained using a tracking device;

    determining, in the coordinate system of the tracking device, location information regarding one or more position indicating elements rigidly associated with an ultrasound simulator using the tracking device;

    determining an imaginary scan plane of an ultrasound simulator in a the coordinate system of the tracking device;

    determining an intersection of the imaginary scan plane of the ultrasound simulator through the volumetric image data of the anatomy of the patient using the location information of the one or more position indicating elements;

    formatting at least a portion of the volumetric image data into a display of the anatomy of the patient intersected by the imaginary scan plane; and

    displaying a location of a tracked instrument on the display, the tracked instrument including one or more position indicating elements tracked by the tracking device.
