Basic Properties of OrthoChromic Film OC-1

OrthoChrome film was designed to be the most robust and user friendly dosimetry tool.
The special coating layer is water proof and can be safely immersed into water - structure is shown in the Figure below.

The reflective nature of the film is designed to eliminate most of the interfaces that can create artifacts during scanning process with commonly used flatbed scanner.
The flexible nature of the film also enables the use of the film in phantoms of all shapes and curvatures.
The newly developed active component has an absorption peak at 670 nm as shown in the Figure below.

The active also exhibits very little commonly seen scanner lateral variation and hence enables more accurate dose measurement for large area.
OrthoChromic film OC-1 was designed to have extremely wide usable dynamic range. As shown in Figure below, the usable dose range extends from 10 cGy to 100 Gy, covering every possible use in radiation therapy.
