Summary
Computed Radiography (CR) is a method used in x-ray radiography to generate digital images. It uses photo-stimulated luminescence to store the x-ray exposure into a latent image, which is then digitized.
Key points:
- CR is a digital replacement for X-ray film radiography.
- CR uses phosphor image plates to create digital images.
- CR systems consist of image recording system, image reading system, identification, and CR processing workstation, and dry imager.
- The major advantages of using CR systems are shorter exposure time and elimination of chemical processing.
- CR imaging process includes pre-processing and post-processing.
- DR systems offer superior throughput compared to CR systems.
- In medical terms, CR also stands for closed reduction, a procedure in surgery for setting broken bones.
Questions and Answers
1. What is the difference between DR system and CR system?
DR uses flat panel detectors based on direct or indirect conversion of X-rays to charge, while CR uses cassette-based phosphor storage plates.
2. What are the components of the CR system?
The CR system includes image recording system (cassettes & reading plates), image reading system (reader/ digitizer), identification & CR processing workstation, and dry imager.
3. Why is CR better than DR?
DR offers superior throughput compared to CR because it embeds the imaging processing cycle in the acquisition task.
4. What does CR mean in X-ray?
CR stands for Computed Radiology, which is the digital replacement of X-ray film radiography.
5. What does the CR imaging process consist of?
The CR imaging process consists of pre-processing, involving correction of flaws in image acquisitions, and post-processing, involving manipulation of pre-processed data.
6. What is one of the major advantages of using CR or DR systems?
Both CR and DR systems require less exposure time than film radiography and eliminate the reliance on chemicals for processing.
7. What does CR stand for in medical terms surgery?
In medical terms, CR stands for Closed Reduction, a procedure used to set broken bones without cutting the skin open.
What is the use of CR system
Computed Radiography (CR) is a method to generate digital images in x-ray radiography that uses photo-stimulated luminescence to store the x-ray exposure into a latent image, that is then digitized.

What is the difference between DR system and CR system
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.

What does CR mean in xray
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 components of the CR system
CR system should broadly comprise of following modules/ components: a) Image recording system (cassettes & reading plates) b) Image reading system (reader/ digitizer) c) Identification & CR processing workstation. d) Dry imager.
What is one of the major advantages of using CR or DR systems
Both CR and DR systems generally require far less exposure time than film radiography. Both offer high latitude images and eliminate the reliance on chemicals for processing.
What does the CR imaging process consist of
What does the CR imaging process consist of Consists of pre-processing and post-processing. Pre-processing includes all processing of raw data performed to correct flaws in image acquisitions. Post-processing includes manipulation of data that has been pre-processed.
Why is CR better than DR
DR offers superior throughput compared to CR because it embeds the imaging processing cycle in the acquisition task: images can appear as quickly as five seconds. CR involves more steps because cassette processing takes longer.
What does CR stand for in medical terms surgery
Closed reduction is a procedure to set (reduce) a broken bone without cutting the skin open. The broken bone is put back in place, which allows it to grow back together in better alignment.
What is a CR on patients
[CR (Computed Radiography)]
Several recent studies have a questionnaire survey of many hospitals regarding the radiation exposure conditions of X-ray examinations.
What is the difference between DR and CR in radiology
The difference between a Digital Radiography (DR System) and Computed Radiography (CR System) is simply that – DR system is truly a digital X-Ray while CR system is not an X-Ray machine at all. It is like comparing apples to oranges.
What are the main components of computed radiography
Three factors are directly responsible for computed radiography image resolution : 1). The dimension of the crystals in the imaging plate, 2). The size of the laser beam in the reader, and 3). The image-reading matrix.
What is the difference between DR and CR in accounting
DEBIT AND CREDIT CONVENTION
This means that entries of equal and opposite amounts are made to the Finance System for each transaction. As a matter of accounting convention, these equal and opposite entries are referred to as a debit (Dr) entry and a credit (Cr) entry.
What are the pros and cons of computed radiography
In comparison to a film/screen combination, a CR system has advantages including a large dynamic range, reduced repeat rates, digital image storage, and image manipulation. – 3 The disadvantages include reduced spatial resolution and higher start‐up costs.
What is a CR imaging test
Computed radiography (CR) is a digital imaging technique widely used for dental, medical, and veterinary diagnostics. Instead of a conventional X-ray film, CR uses a special X-ray sensitive, photo-stimulable phosphor plate also known as an imaging plate (IP).
What is the difference between CR and CT scan
Both DR and CR modalities produce a 2D image of the object. In contrast, CT systems produce a 3D image that is created by taking multiple image 'slices' (usually many thousands) at different angles around a single axis of object rotation.
What are the disadvantages of CR
Disadvantage of CR systems • Spatial resolution is usually lower than that with conventional screen-film combinations. Long time to view image. Risk of over-exposure. High maintenance.
Is CR or DR more expensive
Often considered the most initially cost friendly choice, CR is used almost exactly like conventional film, and so requires few changes to your office or workflow, and requires a smaller initial investment compared to DR devices of similar quality.
What does CR stand for in medical terms Bloods
What is a creatinine test This test measures creatinine levels in blood and/or urine. Creatinine is a waste product made by your muscles as part of regular, everyday activity. Normally, your kidneys filter creatinine from your blood and send it out of the body in your urine.
What does CR mean in medical terms
Pharmaceutical companies use a variety of abbreviations to denote short- and long-acting medications. Commonly used abbreviations include CR for “controlled release”, SR for “sustained release”, ER for “extended release”, and IR for “immediate release”.
What does CR stand for medical
What is CR CR stands for "computed radiography".
What does Dr or CR mean
DEBIT AND CREDIT CONVENTION
As a matter of accounting convention, these equal and opposite entries are referred to as a debit (Dr) entry and a credit (Cr) entry. For every debit that is recorded, there must be an equal amount (or sum of amounts) entered as a credit.
What is computed radiography in simple terms
What is Computed Radiography (CR) Computed Radiography — or CR for short — is the use of a Phosphor Imaging Plate to create a digital image. CR uses a cassette based system like analog film and is more commonly considered to be a bridge between classical radiography and the increasingly popular fully digital methods.

What is CR accounting
In bookkeeping and accounting, CR or Credit means a general ledger account with an entry on the right side. Credit entries increase the credit balance on the liability side and decrease the debit balance on the asset side.
