Dosimetric validation of a magnetic resonance image gated radiotherapy system using a motion phantom and radiochromic film. [PDF]

open access: yesJ Appl Clin Med Phys, 2017
Purpose Magnetic resonance image (MRI) guided radiotherapy enables gating directly on the target position. We present an evaluation of an MRI‐guided radiotherapy system's gating performance using an MRI‐compatible respiratory motion phantom and ...

Effect of scanner lens on lateral response artefact in radiochromic film dosimetry. [PDF]

open access: yesPhys Eng Sci Med, 2022
Radiochromic film is a good dosimeter choice for patient QA for complex treatment techniques because of its near tissue equivalency, high spatial resolution and established method of use.

Application of a Portable Colorimeter for Reading a Radiochromic Film for On-Site Dosimetry

open access: yesApplied Sciences, 2023
Radiochromic films have widely been used for quality assurance (QA) in radiation therapy and have many advantageous features such as self-developing visible coloration, wide dose range and easiness to handle.

Dose- rather than fluence-averaged LET should be used as a single-parameter descriptor of proton beam quality for radiochromic film dosimetry. [PDF]

open access: yesMed Phys, 2020
Purpose The dose response of Gafchromic EBT3 films exposed to proton beams depends on the dose, and additionally on the beam quality, which is often quantified with the linear energy transfer (LET) and, hence, also referred to as LET quenching ...

Measurement of energy dependence for XRCT radiochromic film [PDF]

open access: bronzeMedical Physics, 2006
Gafchromic XRCT, radiochromic film is assessed over a broad energy range, from kilovoltage to megavoltage x rays for variations in reflected optical density to dose response. A large energy dependence was found with reflected optical density output for the same delivered dose varying from 7.8 +/- 0.35 at 25.5 keV (50 kVp) peaking at 12.1 +/- 0.5 at 54 ...

Investigation of dosimetric characteristics of radiochromic film in response to alpha particles emitted from Americium‐241 [PDF]

open access: hybridMedical Physics (Lancaster)
BACKGROUND In radiotherapy, it is essential to deliver prescribed doses to tumors while minimizing damage to surrounding healthy tissue. Accurate measurements of absorbed dose are required for this purpose.
