Principal Component Analysis of EBT2 Radiochromic Film for Multichannel Film Dosimetry

Radiochromic film with a dye incorporated into the radiation sensitive layer [Gafchromic EBT2, Ashland, Inc.] may be digitized by a color transparency scanner, digitally processed, and calibrated so that a digital image in units of radiation absorbed dose is obtained. A transformation from raw scanner values to dose values was developed based upon a principal component analysis of the optical d...

Film Badge Dosimetry Versus Luminescence Dosimetry

The field of personnel radiation monitoring is presently in a state of radical change. It appears that the unreliability of the film badge is now firmly established, bringing into question the value of much of the massive amount of personnel dosimetry data accumulated in the past three decades. This article examines the evidence "against" the film badge and reviews the comparative studies "for"...

Small photon field dosimetry using EBT2 Gafchromic film and Monte Carlo simulation

Background: Small photon fields are increasingly used in modern radiotherapy especially in intensity modulated radiation therapy (IMRT) and stereotactic radiosurgery (SRS) treatments. Accurate beam profile and central axis depth doses measurements of such beams are complicated due to the electron disequilibrium. Hence the EBT2 (external beam therapy) Gafchromic film was used for dosimetry of sm...

A study of surface dosimetry for breast cancer radiotherapy treatments using Gafchromic EBT2 film

The present study quantified surface doses on several rectangular phantom setups and on curved surface phantoms for a 6 MV photon field using the Attix parallel-plate chamber and Gafchromic EBT2 film. For the rectangular phantom setups, the surface doses on a homogenous water equivalent phantom and a water equivalent phantom with 60 mm thick lung equivalent material were measured. The measureme...
