Scanning water phantom to optical laser CT scanner conversion kit

Optical computed tomography (CT) scanners have been developed for quantitative reading of dose images written into radiation sensitive gels. Laser equipped, single ray CT scanners, similar to the first generation x-ray CT scanner geometry, provide high quality data because of efficient scatter rejection. These systems are effective for quantitative transmission measurements with both polymerization and radiochromic gels. Widespread research into optical CT gel dosimetry is limited by the lack of readily available commercial instruments. This project demonstrates how scanning water phantoms, which are common equipment in radiotherapy institutions, can easily be modified to perform optical laser CT scanning
