What happens to image quality with a delay in processing in CR?

Image quality improves
Image quality remains consistent
Image quality degrades
Image quality fluctuates

The correct answer is: Image quality degrades

When there is a delay in processing in Computed Radiography (CR), the quality of the resulting images typically degrades. This degradation can be attributed to several factors. First, CR systems rely on the photostimulable phosphor plates to capture and store image data after exposure. If there is a delay in processing, particularly if the plates are not processed promptly, they may become exposed to ambient light or scatter radiation, leading to loss of image detail and increased noise in the final image. Additionally, the longer the delay, the more susceptible the image data is to chemical reactions that might occur within the phosphor material, which may also negatively affect the clarity and sharpness of the images. In essence, the need for timely processing in CR is essential to ensure optimal image quality, as delays can introduce variables that contribute to a less sharp and informative radiograph.
