Evaluation of EBT radiochromic film using a multiple exposure technique

Abstract: Radiochromic film is a self developing two-dimensional dosimeter system that is widely used in radiotherapy. Since its development some 40 years ago many improvements have been made; however the sensitivity can vary across the film and a non-linear dose response remains. The former can be addressed using a double exposure technique; however this technique assumes that the response is linear so that the dose distribution is incorrectly measured. We are proposing the use of two homogenous exposures; one performe… Show more

“…Different studies have used different time, ranging from hours to days, for leaving the film in the box before scanning. Roozen [ 25 ] stated that 2–3 h is sufficient to stabilise the response of EBT film, referring to information from the manufacturer. Rink [ 26 ] presented a graph of time versus change of OD, showing insignificant change after 2 h. In this study, irradiated EBT3 films were left in the box for 2 h and then scanned using an Epson V700 [ 24 ].…”

“…For the latter, a hole was cut in the middle of a scanner bed and the lm piece was placed over the hole to scan it with no bed directly beneath the area of interest. Irradiated EBT3 lms were left in the box for two hours [25], [26] and then scanned using the EPSON V700 scanner with the above 'beds'. The lm piece was taped down to the bed to atten the curvature.…”
