Which technology is essential for digital image processing in radiography?

Digital sensors are crucial for digital image processing in radiography because they convert X-ray radiation into digital signals, allowing for the immediate creation and manipulation of images on a computer. This technology facilitates various advanced imaging techniques, enhances image quality, and supports post-processing capabilities such as adjustments in contrast, brightness, and detail enhancement.

In contrast, analog film relies on chemical processes and physical development, which are not suitable for digital workflows. Conventional radiographic films require development using chemicals, which introduces delays and limits the ability to efficiently edit or analyze images. Similarly, chemical developing machines are tied to analog film processes and do not play a role in digital image acquisition or processing. Thus, the use of digital sensors is essential for the workflow and advantages offered by digital radiography, making them the correct answer in this context.
