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 because of its 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, we offer Precision Cut radiochromic film.

Our Precision Cut Film is laser cut and designed to fit within the constructs of a specified phantom. We currently offer film configurations for the following phantoms or it’s components:
- E2E SBRT Phantom, Model 036A*, Model 036S & 036-01
- SRS Multi-Lesion QA Phantom, Model 037
- Stereotactic End-to-End Verification Phantom, Model 038
- IMRT Phantoms, Model 002 Series
- Dynamic Thorax Phantom, Model 008A
For schematics and orientation directions of films cut for these products, please see page 2 of datasheet. Additional film configurations can be cut on a custom basis.
Film expiration date will be a minimum of 6 months from invoice date.
* Model 036A has been discontinued. However, film is available to order.
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.
