Film/Screen Contact Test Tools

Film/Screen Contact Test Tool

Routine testing of all of the cassettes in the department detects areas of poor film-screen contact as part of the QA process before blurred areas interfere with patient care. Such testing is often a regulatory requirement. The 142D and 143D film-screen contact tools can test cassettes of any size up to 14x17 inches. Both are enclosed in a protective cover.

Economy Screen/Film Contact Mesh

The film/screen contact test tool determines the clarity of the focused image. This device allows problems to be identified so that image clarity can be restored. It consists of a 14 x 17 inch (35.6 x 43 cm) copper screen, with 0.125 inch (0.3 cm) mesh, embedded in durable plastic for long life use.

To use, simply lay the unit over the cassette, radiograph, and develop the film. Look for screen image clarity across the film. Blurring or distortion indicates poor film/screen contact.
