Abstract
Methods and apparatus for calibrating images and imaging devices to common coordinate systems utilize, in some embodiments, rods that detectably reflect an acoustic signal regardless of the incidence angle of the signal with respect to the rods. Typically, the rods are disposed within a 'phantom' at known positions with respect to a room coordinate system. Images of the cylindrical rods may be obtained from different directions, allowing the imaging device to be calibrated to the room coordinate system.
