Radiochromic film dosimetry system: from calibration to in vivo measurements and IMRT quality assurance measurements.

摘要

A radiochromic film dosimetry system is presented for the radiochromic film model EBT-2 using a flatbed document scanner, the Epson Expression 10000XL model, as a densitometer. The author presents the protocol for radiochromic film dose measurements along with the characterization of the radiochromic film dosimetry system. Results from the measurements taken to characterize the system are presented as well as other typical clinical measurements such as quality assurance measurements and skin dose measurements. Finally intensity modulated radiation therapy (IMRT) quality assurance measurements are presented and compared with the MatriXX ionization chamber array system.
