Define image receptor (IR) - CORRECT ANSWER A device that receives the energy of the
x-ray beam and forms the image of the body part
List the four types of IRs used in diagnostic radiology - CORRECT ANSWER Solid-state
digital detector, photostimulable storage phosphor image plate (IP), fluoroscopic image receptor
(IR), and cassette with film.
According to the recommended procedural steps, what should the radiographer do before
releasing or returning the patient? - CORRECT ANSWER Evaluate the radiograph
