Abstract
A targeting device defines a direction of approach to a subsurface target under guidance of imaging equipment such as a computer tomograph or a magnetic resonance imaging machine. The targeting device is positioned relative to the target in such a way that the optimal direction of approach avoiding vital internal structures can be selected by reference to the images displayed on the imagine equipment. The device projects a visible light beam, such as a laser beam, on a region of a patient, indicating the point of entry and the angle of approach to the subsurface target.
