TECHNOLOGY: INNOVATION

Scintillator Matrix Technology overcomes the inherent drawbacks conventional digital x-ray detectors are afflicted with, namely a tradeoff between resolution and sensitivity.

 

While the visible light created through x-ray absorption spreads on its way through the crystal in unstructured scintillator plates, the innovative concept developed and patented by Scint-X channels the light on its way to the CCD camera.

 

Narrow channels are etched into silicon in order to manufacture a matrix that can be filled with a scintillator material like Thallium doped Cesium Iodide. When x-rays enter those channels, they are converted into green light, which is reflected by the channel sidewalls and therefore does not leave the channel.

Scintillator Matrix Technology: In a structured scintillator light is confined to a channel and does not spread out.

Thus, spreading of created light, that would lead to crosstalk between neighbouring pixels on the CCD chip, can be avoided. This means that the structured scintillator can be optimized with respect to sensitivity without loss of resolution.
