What does the term 'image receptor' encompass?

The term 'image receptor' refers to any device or medium that captures and forms images from the radiation emitted by the object being imaged, which is a fundamental concept in radiography. This includes both film-based systems, where the image is created on a physical film, and digital imaging systems that use sensors to capture images in electronic form.

Understanding this term is crucial because it helps differentiate between the various modalities in radiography. By encompassing all forms of image capture, the term underscores the evolution and flexibility of imaging technologies, highlighting the shift from traditional film to modern digital methods while recognizing that both serve the primary function of producing diagnostic images. This distinction is important in the context of equipment selection and understanding the specific technologies used in clinical settings.
