The dose response of Gafchromic XRCT radiochromic film hasbeen measured with reflectance spectrophotometry and desktop scanners. The film automatically changescolour upon irradiation, changing from a yellow to a green/brown colour. Results show a high sensitivity todelivered dose compared to other conventional radiochromic films which is well suited to CT applicationswhere lower applied doses are delivered. Sensitivity is found for this film with a 1cGy applied dose,producing an approximate net optical density change of 0.3 at 636nm and 0.2 net OD using broad band white light. This high sensitivity combined with its relatively energy independent nature around the 100kVp to150kVp x-ray energy range provides a unique enhancement in dosimetric measurement capabilities overcurrently available dosimetry films for CT applications.
