Surface dose measurements of kV XVI cone-beam CT system using NanoDot optical stimulated luminescence dosimeters
Surface doses received during seven different imaging protocols (using the kV XVI imager) were measured on a Rando phantom surface using nanoDot optical stimulated luminescence dosimeters (OSLD) for three different body regions (head and neck, chest and pelvis). For each protocol, the surface dose was measured at four different locations on the surface of the phantom (ANT., POST., LLAT. and RLAT.). The surface dose at any location in the irradiated area can range between 0.008 cGy (fast head and neck protocol) and 4.38 cGy (symmetry 4D). The average surface dose in the irradiated area ranged between 0.038 cGy and 2.34 cGy. The measured doses were compared with nominal scan dose, provided by the vendor and calculated doses. © 2013 Springer-Verlag.
