A fast dual wavelength laser beam fluid-less optical CT scanner for radiotherapy 3D gel dosimetry II: dosimetric performance.New clinical radiotherapy dosimetry systems need comprehensive demonstration of measurement quality.  In this work the performance of an optical CT scanner for true 3D dosimetry is assessed using a radiochromic gel dosimeter.  The most significant limitations of the system were due to the gel dosimeter rather than the optical CT scanner.
