Which component of a radiographic system converts x-rays into an electronic signal?

The image receptor is the component of a radiographic system that converts x-rays into an electronic signal. This transformation is crucial for imaging because, after x-rays pass through the patient, the image receptor—often a digital detector or film—detects the x-rays and produces a corresponding electronic signal. This signal is then processed to create the final image that can be interpreted by a radiologist or clinician.

The effectiveness of the image receptor is integral to the quality of the radiographic image as it determines how well the system can capture the details of the structures within the body. Efficient conversion and detection of x-rays enable various types of imaging modalities, including computed radiography (CR) and direct digital radiography (DR).

In contrast, the control panel is primarily used for managing the operating parameters of the radiographic system, such as exposure time and tube current, rather than converting x-rays. The generator provides power to the x-ray tube but does not play a role in the conversion process. The collimator is used to shape and limit the x-ray beam before it reaches the image receptor, controlling the area exposed to radiation but does not contribute to the conversion of x-rays to electronic signals.
