Absorption spectra of irradiated XRCT radiochromic film [PDF]
Physics in Medicine and Biology, 2006 Gafchromic XRCT radiochromic film is a self-developing high sensitivity radiochromic film product which can be used for assessment of delivered radiation doses which could match applications such as computed tomography (CT) dosimetry. The film automatically changes colour upon irradiation changing from a yellow to green/brown colour.

Small fields measurements with radiochromic films
Journal of Medical Physics, 2015 The small fields in radiotherapy are widely used due to the development of techniques such as intensity-modulated radiotherapy and stereotactic radio surgery. The measurement of the dose distributions for small fields is a challenge. A perfect dosimeter should be independent of the radiation energy and the dose rate and should have a negligible volume ...

Radiochromic film dosimetry: Reflection vs transmission scanning
Medical Physics, 2008 The objective of this study was to compare the transmission and the reflection scanning reading modes of radiochromic MD‐55 films of a document scanner. The use of the red channel of the red‐green‐blue images results in measurement accuracy that did not differ between the two reading modes.

Radiochromic film for medical radiation dosimetry [PDF]
Materials Science and Engineering: R: Reports, 2003 Abstract Photon, electron and proton radiations are used extensively for medical purposes in diagnostic and therapeutic procedures. Dosimetry of these radiation sources can be performed with radiochromic films, devices that have the ability to produce a permanent visible colour change upon irradiation.

Implementation of an intraoperative electron radiotherapy in vivo dosimetry program [PDF]
, 2016 Background: Intraoperative electron radiotherapy (IOERT) is a highly selective radiotherapy technique which aims to treat restricted anatomic volumes during oncological surgery and is now the subject of intense re-evaluation.
