This theory module provides a thorough introduction to radiographic film and film processing, handling and storage. It also covers special imaging methods such as tomography and magnification radiography. It offers students and practitioners the knowledge of how analog images are created on film, and how to process radiographic film accurately, in preparation for working with real X-ray equipment.
You’ll learn
how radiographic film is constructed and the different types of film
to identify the chemical components, interactions and processes required to create a radiograph
to identify the different systems within the automatic processor
the characteristics of intensifying screens and their care
how to handle and store radiographic film
what specific precautions are required to meet health and safety standards when processing radiographic film
the principles of tomography and magnification radiography
much more (see “content details” for more specific information)
