Laser Reflectance Imaging of Curved Tissue-equivalent Phantoms

The surface backscattered radiations of curved tissue-equivalent phantom are measured using miniature multi-probe laser reflectometer imaging system. Phantom models are prepared using paraffin wax mixed with wax colors and their optical parameters are determined by comparing measured backscattered profile with that of Monte Carlo simulation procedure. Abnormalities with optical parameters 5% less than the normal phantom are introduced at various depths in different locations. These phantoms are scanned using miniature laser reflectometer scanner. The acquired data after digitizing, interpolation and filtering is represented as 3-D color coded images which show the location and size of the abnormalities
