Digital Portable Radiography Equipment
The Development of Portable Direct Digital Radiography Equipment
The objective of this work is to discuss the development of portable direct digital radiography equipment.
The portable direct digital radiography system utilizes plate that is 8 X 10 sized as well as an X-ray generator in the acquisition of a diagnostic-quality image and in a matter of seconds transfers the image, via a cable to a notebook computer for viewing and storing. This application of rapid capture and display is important in situations where there is not a film processor available. The diagnostic capability is enhanced and avoids the restrictions of film expense, film processing and the storage of the processed images. The portable direct digital radiography system utilizes an amorphous silicon digital array plate to produce an immediate diagnostic-quality image."
Computed Radiography Advantages and Disadvantages
The advantages of computed radiography are stated to be (1) a digital image is generated; (2) ability exists to retrofit to existing radiography equipment; (3) mobile radiography is easily accomplished; (4) excellent image quality; and (5) CR is initially less expensive than DR. The disadvantages of CR are stated to be: (1) still have to use an imaging plate; (2) no real time saving benefit over traditional radiography; and (3) need to purchase an imaging reader. (CR vs. DR: The Showdown)
The Development of DR Explained
Prior to the advent of digital radiography there was a waiting period on the development of the image. If the exposure needed to be repeated there was a great deal of time lost in the process. With the advent of digital radiography, the image can now be immediately displayed. With the CR system there are more steps involved from loading the bucky tray to the waiting on the image to be processed however, with the DR imaging there are only two steps: (1) The imaging sensor is exposed by x-rays; and (2) An image appears on the computer screen.
