Tomographic images of biological materials using laser CT imaging system

Tomographic images of biological materials, for example, phantoms of Polyethylene, Polycarbonate, Nylon and Plexiglas with 10 mm diameter with internal bores of 2 to 5 mm diameter and length containing Intralipid-10% solution in various concentrations are obtained. The concentration is defined as the percentage of the volume of the Intralipid-10% against that of water, and the region of interest. In addition to these, the phantoms are filled with few other soft materials (external shell with internal soft material) and the images are obtained. The data acquisition and image reconstruction procedures of the laser CT system are similar to those of X-ray CT. The images are acceptably distinct. Based on experimental observation of the images, the present system can reconstruct images of small objects and soft materials in the trans-illumination mode. In addition, we have studied partially the dynamical properties of the embedded biological soft tissue of a snail.
