Question

When it comes to digital image receptors, there are a few different systems that can be used. In general, the latent image is captured on the digital detector and is then processed by a computer. Once the image is displayed on the computer, it can be altered before it is sent to the radiologist.

During your clinical rotations and/or once you graduate, you may work with CR systems or DR systems. For this assignment, you will investigate the digital imaging process for both CR and DR types of systems.

Assignment Requirements

For this assignment, you will need to create 2 single-page educational flyers -- one for CR systems and the other for DR systems. Both flyers should be created within the same Microsoft Word document.

Your CR and DR flyers should be developed as handouts which would be appropriate for new radiology students who are going to complete clinical rotations in an environment using digital image receptors (do not include any of the film screen imaging information). Be sure to use proper spelling/grammar and language that is appropriate for the intended audience.

Each of your flyers should include:

an overview of how the system works -- how the digital image receptor obtains the radiographic image and transfers the radiograph it to the computer.
an explanation of what can be done once the image is on the computer.
any advantages/disadvantages of the different types of image receptors.

Be sure to include APA citations for any references you use.

COMPUTED RADIOGRAPHY
OVERVIEW
Computed radiography (CR) can be considered the digital form of X-ray radiography. It has several advantages over the conventional X-rays in terms of both accuracy and clarity. The images are produced in a short amount of time with greater precision. The main feature of Computed Radiography is the use of phosphor plates to store images. (Neitzel, 2005)
ADVANTAGES
· Reusable Imaging plates
· Reduced exposure time.
· Computer-based evaluation and reporting
· Detailed visuals
· Simplified workflow
· Safe working environment
· Environment-friendly
· Chemical-free process
DISADVANTAGES
· Image generation takes time
· Overexposure risk
· Costly Maintenance
MAIN FEATURES OF CR TECHNOLOGY
· Imaging phosphor plates used instead of film.
· Imaging plate is digitized and erased for reuse.
· The digital image is processed using special software.
HOW CR TECHNOLOGY WORKS?
1- First, the Imaging plates are exposed to X-rays or gamma rays. The resulting image in the form of energy from this radiation is then stored in a phosphor layer plate. 
2- A scanner is then used to read the image from the plate. This is done by stimulating it with a very fine laser beam. 
3- Upon stimulation, the plate emits blue light.
