Digital radiography
Updates to Article Attributes
Digital radiography is based on the use of discrete values in comparison to conventional radiography which uses analogue/continuous values. It removes the requirement of dark room procedures.
Digital radiography does not use cassettes. It uses direct or indirect flat panel detectors or charge coupled devices (CCDs)
Types
-
computed radiography (CR)
uses photostimulable phosphor plates (PSP) in cassettes
-
direct digital radiography (DDR) 1
using photoconductor ---> convert x-ray direct to charges (+ and -) then read by TFT array
-
indirect digital radiography (IDR) 1
uses scintillator layer ---> convert x-ray to light photons ---> Photodiode----> photons to electrons -----> readout by TFT array
