What is the correct sequence of steps in Computed Radiography (CR) from first to last?

• A. Expose, stimulate, read, erase
• B. Read, erase, expose, stimulate
• C. Stimulate, expose, read, erase
• D. Erase, stimulate, expose, read

Answer: (A)

In Computed Radiography (CR), the sequence of steps begins with exposing the imaging plate to radiation. This exposure captures the latent image on the photostimulable phosphor (PSP) layer. After exposure, the next step is to stimulate the imaging plate with a laser beam. This stimulates the trapped energy, causing it to release light, which is then read by a photomultiplier tube. Finally, the imaging plate must be erased to clear any residual input and prepare it for the next exposure. This systematic approach of expose, stimulate, read, and erase is critical to ensuring high-quality imaging while allowing for reusability of the imaging plates. The other sequences do not reflect the correct order necessary for the CR process to function properly, as they either begin with the wrong step or misplace the crucial steps involved in stimulating and reading the plate.
