- Photon counting X-ray detection technology

- Photon counting detection technology comes 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.
- Size: 1.5.
