What is meant by "image receptor" in dental radiography?

In dental radiography, the term "image receptor" specifically refers to the medium that captures the x-rays and produces the radiographic image. This can be in the form of traditional film or digital sensors that convert the x-ray exposure into a visual representation. The primary function of the image receptor is to interact with the x-rays generated by the x-ray tube, recording the varying densities that result from the different tissues being imaged.

While digital sensors and film do this job, other options do not represent what an image receptor is. For instance, a device to stabilize the x-ray tube is not involved in capturing images, nor is a tool for measuring radiation levels related to the direct process of forming radiographic images. Therefore, the designation of film or sensor encapsulates the essential role of the image receptor in the dental radiographic process.
