Abstract

This optical tomography scanner for imaging (3D) applied density distribution as been evaluated for uniformity, resolution, and linearity. Signal to noise ratio of about 1000:1 in both line projection and in back projection reconstructed image has been obtained. Radiation-sensitive BANG^R polymer gels were studied using this system. Dose as low as 10 cGy up to 10 Gy for 6 MV X-ray and 6 MeV electrons from linear accelerator have been measured. Since the gels can be made UVlight sensitive, dose distribution could be used to measure exposure using this technique.
