Which of the following is not a component of a computed radiography plate reader?

In a computed radiography (CR) system, the basic components work together to capture, process, and display radiographic images. The photostimulable phosphor is crucial as it captures the X-ray image and stores it until it is stimulated by a laser to release the stored energy as light, which is then converted into a digital image. The laser scanner reads the light emitted from the photostimulable phosphor and converts it into an electronic signal. The image processor then takes this electronic signal and processes it to produce a final image that can be viewed and utilized by healthcare professionals.

Developing solutions, on the other hand, are traditional components used in film-based radiography, where chemical processes are necessary to develop images on film. In computed radiography, the process is entirely digital and does not use chemical developing solutions. Thus, this option does not belong to the components of a computed radiography plate reader, making it the correct answer.
