Photon counting detection technologycomes from high energy physics. With decades of development, it has been one of the leading and heated technology in the X-ray imaging detector.

The photon counting detector can control the threshold value through the electric circuit, resulting in the following benefits. First weak noises can be shielded, and second by controlling the threshold value, X-ray energy differentiation can be achieved rather than simply differentiating the X-ray quality. This helps to make Silhouette imaging and color CT imaging.

Direct Conversion

Both CCD and a-Si detectors makes indirect conversion, which not only yields low X-ray conversion rate, but also due to scattering light, spatial resolution is reduced.The a-Se detector makes direct conversion, but has strict requirements for the operation environment.The production volume is limited and the maintenance cost is huge.It is also prone to problems.XpectVision’s photon counting detector is much more robust since it is made from semi-conductor materials. The direct conversion avoids scattering made by the scintillator. Zero dark noise and high linearity contribute to extraordinary image quality.

Applications

Photon counting X-ray detection technology can be used in almost all the X-ray detectors that demand high product performance.
