Computed Radiography (CR) Digital Radiography using storage phosphor plates as an intermediate storage media prior to scanning the plate to create a digital image. Implementation is similar to film radiography except that in place of a film to create the image, an imaging plate (IP) made of photostimulable phosphor is used 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 Both computed radiography (CR) and digital radiography (DR) require the use of digital technologies which rely on computer networks and high-bandwidth web facilities A computed radiography scan of a circuit board identifying missing components. Differences between Computed Radiography and Conventional Radiography The CR inspection process is similar to conventional radiography (RT) but has a few key differences.

Digital radiography (Digital CR) was first introduced in the 80s [1] when the first radiograms were recorded on phosphorus-coated digital cassettes. [2] The advantages of digital radiograms include manipulation of digital data at various stages between image acquisition and final interpretation. A wide dynamic range is obtained II. DIGITAL RADIOGRAPHY COMPUTED RADIOGRAPHY (CR) With CR the film is replaced with a flexible Image Plate (IP) which is coated with a phosphor layer. The radiography is carried out in the same way as with film, with the IP inside a light-tight cassette. Once exposed, the IP is returned to a darkened area for processing Since the shift away from screen-film radiography, imaging facilities have two basic choices for digital radiography systems: computed radiography (CR) or digital radiography (DR). With ongoing technological advancements and the significant reduction in price, DR is rapidly becoming the preferred choice

Digital and Computed Radiography systems each offer different advantages and disadvantages over each other. Many actually consider digital radiography X-Ray systems as the next step from computed radiography system owing to the greater safety and image quality advantages that these have to offer. As someone considering adding an X-ray system to. Computed radiography (CR) and digital radiography (DR) are rapidly replacing screen-film imaging systems in many countries. Both are similar in technology except for the image receptor. CR uses photostimulable phosphor (PSP) plates which must be transported to a digital scanner (or reader) and scanned with a laser beam to convert the stored. Computed Radiography (CR)...is the generic term applied to an imaging system comprised of: Photostimulable Storage Phosphor to acquire the x-ray projection image CR ReadCR Readerer to extract the electronic latent image Digital electronics to convert the signals to digital form CR Image Acquisition Phosphor plate X-ray system 1. XX--ray. Introduction. A systematic historical overview of the evolution of digital radiography is shown in , Table 1.Experimental digital subtraction angiography was first described in 1977 by Kruger et al (, 1) and introduced into clinical use as the first digital imaging system in 1980 (, 2).For general radiography, x-ray images were first recorded digitally with cassette-based storage-phosphor.

Introduction. R adiographic artifacts are portions of the image that may mimic a clinical feature, impair image quality, or obscure abnormalities. 1, 2 With the development of digital radiography (DR), a new set of artifacts is introduced. In this article, we will discuss some of the more common artifacts encountered with the two general categories of digital radiographic systems, computed. Digital radiography eliminates the need for automatic film processors, taking with it the odor, wait times and space they require. Digital radiography advantage #6 - Time and productivity savings .
