Using an array of near-infrared (NIR) LED’s, we can obtain transillumination images of an animal body and visualize the veins and arteries in the adult forearm as thick as 6 cm. To examine the feasibility of three dimensional (3D) reconstruction using these transillumination images, experiments were conducted to evaluate the image of an absorber in a tissue-equivalent phantom. An experimental system was designed to obtain a transillumination image of a model of blood vessels in the adult forearm. Imaging was accomplished with a high-resolution cooled digital CCD camera, placed at the opposite side of the phantom to the light source. The transillumination images were obtained with different depths of the absorber from the container wall.
