Precision Cut EBT3 GafChromic(TM) Film

Model 158200
BENEFITS OF PRECISION CUT FILM

Unlike dosimeters, radiochromic film provides a means of measuring true 2D dose distribution within a region of interest. For small field dosimetry, film offers a unique advantage over dosimeters because of it’s high spatial resolution and dynamic range1. These qualities make film a popular solution in many radiotherapy departments.

However, cutting film for use in phantoms can be a tedious task. To save valuable time for clinicians and researchers, CIRS now offers Precision Cut radiochromic film.

FILM CONFIGURATIONS

CIRS Precision Cut Film is laser cut and designed to fit within the constructs of a specified phantom. CIRS currently has film configurations for the following phantom models or it’s components:

  • E2E SBRT Phantom with Removable Spine, Model 036S & 036-01
  • SRS Multi-Lesion QA Phantom, Model 037
  • Stereotactic End-to-End Verification Phantom, Model 038
  • IMRT Phantoms, Model 002 Series

For schematics and orientation directions of films cut for these products, please see page 2. Additional film configurations can be cut on a custom basis. Please contact CIRS for more information.

CARE AND HANDLING

Great care is taken in handling all film, including maintaining film orientation, minimal exposure to UV light, and shielding from skin oils and environmental effects. While film can withstand limited exposure to interior light2, it is recommended that film be stored in provided envelopes and packaging to avoid noticeable effects.

Prior to using film, please refer to Excess Temperature Indica- tor provided in film packaging. If the small box in the center of the indicator is white, film is acceptable for use. If the box is black, the film package has been overheated during transport. Please contact CIRS Customer Service.

USE OF FILM

Each film package includes six calibration strips, which are manufactured from the same lot as Precision Cut film. Calibration of the film can be done once for all included films.

All film must be oriented in the same direction in order to ensure accurate measurements. Refer to page 2 on data sheet for the correct orientation of calibration strips and pre-cut film.
