CT scanners convert analog data to digital data using what device?

CT scanners utilize analog to digital converters to transform the continuous analog signals generated by the detector array into discrete digital data that can be processed and analyzed. This conversion is crucial because computer systems can only work with digital data. The output from the CT detectors, which measure the x-ray attenuation of tissues, is initially in an analog form. The analog to digital converter then takes these signals and encodes them into a digital format, enabling the subsequent image reconstruction and analysis.

Other options, such as digital to analog converters, would be more relevant in contexts where digital data needs to be converted back into an analog signal, which is not the case in the operation of CT scanners. Data compilers and signal processors refer to different processes or components that are not directly involved in the fundamental task of converting analog signals from CT detectors into a usable digital format.
