What is the primary function of image receptors in radiographic testing?

The primary function of image receptors in radiographic testing is to capture radiation and convert it into a visible image. This is fundamental to the process of radiography, where the image receptor interacts with the incoming radiation, whether it be X-rays or gamma rays, to create an image that can be interpreted by radiologists or technicians.

Image receptors are designed to be sensitive to radiation and can vary from traditional film to digital plates and sensors. The capability to convert the incoming radiation into a visible image is essential for diagnosing conditions and assessing the integrity of structures, such as welds or components in non-destructive testing.

The other options provided, while related to radiographic processes, do not capture the primary role of the image receptors. For instance, enhancing resolution through digital manipulation is an important aspect of image processing but does not define the initial role of the image receptor itself. Similarly, measuring radiation exposure intensity and assisting in film processing are supportive functions but not the core job of the image receptor in creating the initial image.
