Means of tracking movement of bodies during medical treatment

A system for improving the accuracy of preprogrammed surgery on a body having an inside portion that is in need of said surgery and an outside portion that is moveable during said surgery, comprising:

• a plurality of markers, that are adapted to emit a corresponding plurality of signals, and that are adapted to be disposed on said moveable outside portion of said body proximate to said inside portion in need of said surgery;
• wherein said markers, respectively, comprise:
• a disposable support element, adapted to be attached to an outside portion of said body;
• a wedge shaped member coupled to the disposable support element;
• and
• a signal emitter coupled to the wedge shaped member;
• means for causing said signal emitters to respectively emit signals under conditions sufficient to differentiate which emitter is sending each of said signals, respectively, wherein emitted signals are adapted to enable tracking the movements of said movable outside portion of said body;
• receiver means disposed remote from said body and positioned to be adapted to receive emitted signals from said signal emitters, respectively;
• means for tracking the movement of said outside portion of said body as a function of said emissions;
• means to identify and map said inside portion of said body that is intended to be subjected to surgery;
• means to preprogram a treatment path adapted to be followed by treatment means;
• means to integrate said tracked movements with said treatment path to form a modified treatment path;
• and
• means to cause said treatment means to treat said inside portion of said body along said modified treatment path while substantially preventing said treatment means from departing from said modified treatment path to any substantial extent,
• wherein said signal emitters and said wedge shaped members are adapted to dispose said signal emitters in line of sight with said receiver means when attached to an outside portion of said body.
