16 sty 2008 · Although categorization of CR as part of the umbrella of DR is tempting and contributes to a broader view of digital radiography, there are specific reasons why CR should be considered a separate imaging modaity.

19 maj 2009 · CR represents the digital technology that can directly replace screen-film imaging at a low initial investment cost and still use existing X-ray equipment with minimal changes or calibration requirements.
30 sty 2008 · Current state-of-the-art digital X-ray systems offer excellent dynamic range with similar or reduced quantum detection efficiency (permitting dose reduction with equivalent image quality) and, along with image processing, offer significant potential to substantially improve on the image quality that is typically achieved with film.
6 mar 2016 · CR imaging requires a two-step process for image acquisition: image capture in the IP and image readout. The latent image is formed in the PSP when the exit x-ray intensities are absorbed by the phosphor and the europium atoms become ionized by the photoelectric effect.
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.
Computed Radiography (CR) radiography effectively replaces X-ray testing by digitising the darkroom process. Like X-ray testing, CR imaging uses cassette-based media and radiation to capture images.
22 lut 2023 · Figure 2.4 shows an overview of the CR imaging process, from data acquisition (x-ray exposure of the image receptor); image processing; and image display. In the first step, image acquisition CR uses an imaging plate (IP) to capture radiation transmitted through the patient during the examination.
