<p>Provided herein are devices and methods for mounting variously configured medical imaging probes (10) to a tracker assembly (100) for imaging applications. In one aspect, a tracker assembly (100) provides multiple degrees of freedom for positioning a probe (10) relative to a patient and/or maintaining a probe (10) in a desired location for imaging purposes. The tracker (100) generates location information that may be utilized as frame of reference information for acquired images. In another aspect a holding device (40) allows for interfacing/holding differently configured probes (10) in a common orientation to a predetermined frame of reference.</p>
