Most common CR IP readers contain which of the following?

• A. DAC and a focusing cup
• B. DAC and a focusing lens
• C. ADC and a focusing cup
• D. ADC and a focusing lens

Answer: (D)

In CR IP readers, the light emitted from the imaging plate after laser stimulation must be turned into a digital image, and that starts with converting the analog light signal into digital form. An analog-to-digital converter is essential because it translates the continuous light signal detected by the photodetector into discrete digital data that the computer can process and store. At the same time, the optical path must efficiently collect and direct that light onto the detector, so a focusing lens is used to keep the light properly focused and preserve image sharpness and resolution. A digital-to-analog converter would reverse the process, which isn’t what happens in these readers, and a focusing cup isn’t a typical component in modern CR readers.
