Which term describes a numeric value representative of the exposure received by the image receptor?

The term that accurately describes a numeric value representative of the exposure received by the image receptor is the exposure indicator. This figure serves as a critical component in digital radiography, providing feedback to radiologists and technicians about the amount of radiation that the image receptor has absorbed. The exposure indicator is essential for ensuring that the image quality is optimal and that patient exposure to radiation is minimized.

In the context of a radiologic examination, the exposure indicator helps in evaluating the adequacy of the exposure for an image—indicating whether the exposure was too high, too low, or just right. It essentially allows imaging professionals to assess and adjust their techniques appropriately in future imaging processes. Overall, understanding exposure indicators is fundamental for maintaining both diagnostic quality and patient safety in radiologic practices.
