The violet light emitted by the PSP is transformed into the visible image by which of the following?

The correct answer is that the violet light emitted by the photostimulable phosphor (PSP) is transformed into the visible image by the analog to digital converter (ADC).

In digital radiography, after the PSP is exposed to radiation, it stores the energy from the x-ray photons. When the PSP is stimulated by a laser during the reading process, it emits violet light as it releases the stored energy. This emitted light is then detected and captured by a photodetector. However, the process does not stop there. The analog signal generated from this light needs to be converted into a digital format for processing and display. This task is performed by the analog to digital converter, which takes the continuous signal (the analog light signal) and converts it into a discrete digital format that can be processed by computer algorithms to create the final visible image.

Understanding this process is crucial in the realm of digital radiography, as it highlights how the conversion from the emitted light to an interpretable image occurs, maintaining the quality and detail of the diagnostic image.
