|
The Gammex 118 Aluminum Stepwedge allows users to examine the effects of changing digital image receptor settings,
film-screen combinations, x-ray generator settings, mAs reciprocity and other factors.
This product is constructed from a single piece of high purity aluminum. The nine steps have thickness ranging from 0.3 mm
to 2.27 mm. This design provides graduated exposure steps to the image receptor.
Note: This device may be used for sensiometric evaluation of film by an expert. However, one of our dedicated
sensitometers is recommended for results independent of x-ray generator variability. |
