1. A disposable calibration boot for an optical catheter having a distal end and having at least one optical means for emitting light radiation from the distal end and at least one optical means for receiving light radiation at the distal end, said disposable boot comprising:

  • a body,a cavity defined in said body to receive the distal end of the optical catheter, said body shielding the distal end of the catheter from ambient light when the distal end is positioned within said cavity;

    said body having a plurality of isolated compartments, each of said plurality of compartments containing a material having a known reflectivity to return a signal into the receiving optical means upon transmission of a known radiation from the emitting optical means,said body adapted to be positioned on the end of the optical catheter and being movable with respect thereto to position the distal end of the optical catheter adjacent each of said plurality of materials within said body such that the emitting and receiving optical means of the optical catheter selectively interacts individually with each of said plurality of materials to obtain separate backscattered signals from each of said plurality of materials within said calibration boot from light radiation caused to be emitted from the optical means of the optical catheter.
