Inside every digital radiography (DR) detector panel is a layer of material called the scintillator. Right now, there are two main chemical compounds being used as scintillators in the manufacture of these panels: gadolinium oxysulfide (Gadox, for short) and cesium iodide (CsI).
Both of these materials are approved for use in diagnostic X-ray, and both of them are readily available in the DR marketplace. So, how does an imaging facility choose between a DR panel with Gadox and one with CsI?
The following are the most significant differences in purchasing and using a Gadox DR panel vs. a CsI panel.
