The digitalization of CR is to replace the film and intensifying screen with a repeatable imaging board (IP board). After exposure, a latent image is generated on the IP board. Put IP board into CR scanner, scan IP board with laser beam, read information, and generate digital image after A/D conversion.
Advantages of CR:
The dose of 1.X-ray photography is smaller than that of traditional X-ray photography.
2. Digitize the image for easy access to PACS system.
3.IP board can be placed flexibly, which is convenient for seriously ill patients with mobility difficulties.
4. Compared with DR, the price is low, and a set of CR can realize the digitalization of X-ray equipment in the whole hospital.
Use:
CR includes the development of software and hardware technologies such as imaging board technology based on photo-excitation phosphorescence technology, image reading technology based on laser, digital image algorithm, etc., which makes CR widely used in hospital radiology. Moreover, due to the lower price of CR equipment and the advantages of digitalization, CR imaging has gradually replaced film imaging, making CR equipment the mainstream X-ray imaging equipment in radiology.
