Any off the shelf video card will be able to run the Barco monitors
A uni-viewer also called a universal viewer or zero foot print viewer used standard DICOM web protocols to access images from an archive or more commonly a VNA. It is called a universal viewer because it uses standard DICOM protocols and works with any PACS system.

With CR if the patient is under-exposed it will create a noisy image
With CR if the patient is over-exposed it will create a noisy image.
Image availability is faster with DR.
DR plates are cheaper to manufacture than CR plates
All CR or DR images get processed the same. A chest image is processed the same as an extremity.
In theory a CR plate should last forever however in reality the lifetime of a CR plate is determined by how well maintained it is.
A typical CR image might produce a 2 by 2.5k image containing ten bits of data
CR plates and DR plates look identical.
A CR plate that works in an AGFA cassette would also work in a FUJI cassette
CR technology uses a
STIMULABLE PHOSPHER PLATE
DR technology uses a

exposing the plate to intense light

EVERY 5 YEARS
What are the two basic DR acquisition technologies?
scintillation method photoconductor method
The DX SOP class has two options for image data output. They are
for processing FOR PRESENTATION
What would happen in the technologist enters the wrong body part or exam type into the CR or DR unit?
The wrong processing algorithm would get applied and the image would not be of diagnostic quality.
if you were a technologist would you rather work in a CR equipped room or a DR equipped room? Why did you choose one over the other?
DR BC IT IS NEW TECHNOLOGY AND FASTER
