The primary function of the analog-to-digital converter (ADC) within the computed radiography (CR) imaging plate reader is to convert electrical signals into digital signals. When a CR imaging plate is exposed to radiation, it accumulates energy in the form of latent image data. Upon processing, this latent image is read out as an electrical signal, typically in an analog format. The ADC's role is crucial because it takes these analog electrical signals, which represent the data captured on the imaging plate, and converts them into a digital format that can be processed and manipulated by computer systems for image display, storage, and analysis.

This digital conversion is fundamental to modern imaging techniques, as it allows for the application of various digital image processing algorithms that enhance image quality, improve diagnostic capabilities, and facilitate storage and transmission of medical images. The resulting digital data can also be easily integrated into electronic health records and shared across different systems in a clinical environment.

Understanding the function of the ADC emphasizes the importance of digital imaging technology in medical radiography, as it serves as the bridge between the physical data captured by the imaging plate and the digital image that radiologists and technicians rely upon for diagnosis and treatment planning.
