Which imaging feature is NOT characteristic of computed radiography systems?

Computed radiography (CR) systems are distinctive for their use of digital imaging technologies rather than traditional film-based systems. One of the key components of computed radiography is the utilization of a storage phosphor plate, which captures and stores the image data in a way that can be later digitized and processed to produce high-quality images.

The process of computed radiography involves the digitization of image data, which allows for enhanced imaging capabilities such as editing and manipulation of the images post-acquisition. The options involving the instant display of images on a computer monitor and the use of storage phosphor plates are true characteristics of CR systems, signifying their modern approach to radiographic imaging.

On the other hand, the use of photographic film is not a characteristic of computed radiography systems. Instead, this is a defining feature of traditional radiography. CR systems have largely replaced film due to the advantages of digital technology, which include faster processing times, reduced radiation exposure, and improved image quality. Thus, the statement regarding the use of photographic film being characteristic of computed radiography systems is indeed the correct answer as it stands in contrast to the principles of CR technology.
