Which technology is described as a filmless x-ray system?

The technology described as a filmless x-ray system is digital radiography. This method captures images using electronic sensors instead of traditional film. Digital radiography allows for immediate viewing of images on a computer screen, which enhances workflow and analysis compared to film-based systems. The digital format also permits easier storage, retrieval, and sharing of images, contributing to more efficient patient care.

In contrast, conventional radiography and film-screen radiography both rely on photographic film to capture images, which requires development and processing, thus making them not "filmless." Computed radiography, while utilizing imaging plates that can be scanned and digitized, still involves a physical medium. Therefore, digital radiography is the true filmless option, providing a modern approach to imaging in medical diagnostics.
