Which of the following technologies is commonly used in digital radiography systems for image acquisition?

The charge-coupled device (CCD) is commonly used in digital radiography systems for image acquisition due to its ability to efficiently convert incoming light signals into electrical signals. This technology facilitates high-quality image capture by capturing a wide range of light intensities with great sensitivity, which is essential for producing clear and detailed images in radiographic examinations. The high resolution and low noise characteristics of CCDs make them ideal for digital imaging applications, allowing for better visualization of anatomical structures and potential abnormalities.

While photomultiplier tubes can also detect light for imaging purposes, they are typically used in applications such as scintigraphy rather than directly in digital radiography systems. Thermographic cameras measure infrared energy rather than X-ray images, and dual energy X-ray absorptiometry (DEXA) is a specialized technique used primarily for measuring bone density, not for general image acquisition. Therefore, the use of CCD technology is pivotal for achieving high-quality images in digital radiography.
