Dosimetry & Research Film by Ashland

Gafchromic™ Dosimetry Film

Radiotherapy & Radiology QA

Gafchromic™ films are designed to provide fast and highly accurate measurements for radiotherapy and radiology applications.

When used with specifically designed filmQA pro™ software, Gafchromic™ film provides the most complete and accurate dosimetric measurement. Instant high resolution images provide the data integrity needed to increase confidence and peace of mind.

Key Features & Benefits

  • High spatial resolution and contrast: submillimeter resolution: 25 µm or less
  • No angular correction or dependence: response is independent of radiation incident angle
  • Tissue equivalent
  • Safe to handle in room light
  • Image develops in real time: no chemical processing required
  • Water resistant: usable with water phantoms
  • Achieve dose accuracy within 2% when coupled with filmQA pro™ software
  • All films can be custom cut to meet the user’s specific needs

Applications

  • Small field dosimetry: SRS/SBRT
  • Patient QA: VMAT, IMRT
  • Radiation field/ light field alignment tests
  • Start shot tests
  • Picket fence tests
  • Flatness and symmetry tests
  • Position verification for HDR
  • Dose mapping

filmQA pro™ Software

A Sophisticated, Quantitative Analysis Tool for Gafchromic™ Film.

FilmQA Pro™ software is a sophisticated, quantitative analysis tool specifically designed to simplify and streamline the intensity-modulated radiation therapy quality assurance (IMRT QA). Our software is also effective for QA of SRS, SBRT and VMAT procedures. It allows you to scan or open images of exposed film and calculate the optimized dose maps.

FilmQA Pro™ software uses proprietary multi-channel dosimetry which eliminates or mitigates film and scanner artifacts by detecting whether errors are being made during scanning. In addition,, the software also has the one-scan analysis feature which combines calibration and plan verification in a single scan. The one-scan protocol requires only the patient film, a reference patch, and an unexposed patch. This protocol eliminates error sources such as interscan variability, which enables you to reduce errors to within 2 percent.

With FilmQA Pro™ software, you can get your results in minutes, post-exposure growth is no longer an issue and there is no waiting overnight for changes in the film to diminish. You can do an analysis any time you want, even at a moment’s notice. The software delivers gamma passing rates ≥ 95 percent at 2 percent at 2 mm instead of using 3 percent at 3 mm.
