What Student Need to Know about Digital Radiographic Image Processing In Radio Diagnosis
Digital radiography, also known as direct digital radiography, uses xraysensitive plates that directly capture data during the patient examination, immediately transferring it to a computer system without the use of an intermediate cassette as is the case with CR. Commonly referred to as plates, these flat panel detectors use a combination of amorphous silicon detectors with cesium or gadolinium scintillators that convert Xray to light which is ultimately translated by thin film transistors into digital data (Fig. 238). This technology is significantly more expensive than CR technology, but the images are of the highest quality and are seamlessly sent to a computer display. These systems are popular in dedicated imaging facilities and hospitals with high workloads. Digital detectors allow implementation of a fully digital picture archiving and communication system, in which images are stored digitally and are available anytime. Image distribution in hospitals can now be achieved electronically by m
