Is computed radiography digital radiography?
Computed Radiology (CR) is the digital replacement of X-ray film radiography.
CR radiography uses phosphor image plates to create a digital image.
Although it is an older technology, it is still digital technology and is more cost effective..
What are the advantages of digital radiography over computed radiography?
Thus, the use of DR is associated with lower patient exposures because of very low imaging failure rates.
The high speed of image acquisition is another advantage of DR technology.
Image quality is excellent with DR whereas CR images are somewhat inferior to film X-ray systems.Nov 27, 2018.
What is the difference between computed and digital radiography equipment?
DR uses flat panel detectors based on direct or indirect conversion of X-rays to charge, which is then processed to produce a digital image.
CR uses cassette-based phosphor storage plates (PSP), which are then scanned by the computerized system into a digital format for image processing, archiving, and presentation.Nov 27, 2018.

What is the difference between computed tomography and radiography?
A CT scan, or computed tomography scan, sends radiation through the body.
However, unlike a simple X-ray study, it offers a much higher level of detail, creating computerized, 360-degree views of the body's structures.
CT scans are fast and detailed..
What is the difference between digital imaging and radiography?
Compared to traditional X-rays, digital X-rays provide better and clearer images with high resolution that can be enlarged or manipulated as needed, minimizing the need for repeating the procedure.
Since traditional X-rays are printed on a film, there is no chance of tampering with them..
What is the difference between digital radiography and computed tomography?

Since traditional X-rays are printed on a film, there is no chance of tampering with them. - Computed Radiography (CR) provides key benefits over film radiography.
Computed Radiography (CR) system lets the radiologic technologist do post processing on the acquired digital image.
This includes zooming, cropping, adjusting of brightness & contrast and even placing annotations and markers. - The CR reading has better spatial recognition for these smaller items.
To achieve similar resolution, a DDA might call for geometric magnification — a process that decreases the number of smaller parts that can be scanned in one image and increases the number of images needed for larger parts.
