Portal radiographs, radiographs made to document the accuracy of radiotherapy treatment fields, are typically of poor image contrast. Recently, a new portal film and screened‐cassette system was marketed, the Kodak EC‐L system, with the claim of greatly improved image contrast. This new EC‐L system was tested on a canine cadaver exposed to Cobalt‐60 teletherapy gamma radiation, and image quality was compared to earlier marketed Kodak portal film products. The EC‐L system was found to provide portal images of improved contrast/quality.
