Digital radiography (DR)

Digital Radiography (DR) is a form of X-ray image diagnosis that uses an X-ray flat-panel detector instead of the conventional X-ray films or imaging plate (IP).

X-ray flat-panel detectors are available in direct and indirect conversion types. The more common type is the indirect conversion type in which x-ray is first converted into visible light through a scintillator and then the visible light is converted into an electrical signal by a photodetector.

We adopted Cesium Iodine (CsI:TI) in the needle-like structure with superior resolution. Scintillators of varying sizes are available for medical and dental applications, as well as for non-destructive testing.

Our scintillators can be deposited onto three different types of substrates: aluminum, amorphous carbon, and fiber optic plates.

To further optimize the X-ray image sensor design and provide the best performance for digital radiography applications, we can offer our CsI Tl scintillators on various substrate materials including: aluminum, amorphous carbon, and fiber optic plates, as well as direct deposition onto an image sensor.


The brochure below explains the construction of Hamamatsu's needle type scintillators as well as various configurations and substrate options. Key features and benefits of each scintillator option are also described to help you select the most suitable scintillator design for each application.
