Which imaging technique uses a photostimulable phosphor as the image receptor?

• A. Computed radiography
• B. Film radiography
• C. Digital radiography
• D. Cineradiography

Answer: (A)

Computed radiography is the imaging technique that uses a photostimulable phosphor as the image receptor. This technology involves the use of imaging plates coated with a phosphor material, which captures X-ray images when they are exposed to radiation. After the exposure, the plate is processed in a reader that stimulates the phosphor with a laser beam, causing it to emit light. This emitted light is then converted into an electronic signal to create a digital image. This technique allows for the advantages of digital imaging—such as enhanced image quality, the ability to manipulate images post-acquisition, and reduced patient dose—while still using a method that originally captures data similar to traditional film.
