Future Technology

The XC-Pyxis is a single-element, hybrid detector technology that can be assembled into larger detectors without gaps between the elements. This near seamless construction has a direct impact on the image quality obtained as it reduces potential artefacts and eases the capture of images, as well as making it possible to engineer detectors of different sizes and shapes.

Through Silicon Vias (TSV) technology enables signals to be routed through the back of the chip. This avoids having wires at the sides so the chip can be tiled more closely to its neighbours.

As well as enhanced image quality and the potential for an increase in the size of the tiled detectors, the XC-Pyxis is being designed with a number of other important features. Currently, these include the acquisition of data in up to six energy bins per pixel and on-chip binning which widens the possible uses of the detector by improving separation of contrast media in an image and improved separation of body tissue.

X-ray Detectors


The XC-Thor series of photon counting detectors is especially suited for medical research applications due to their extremely high speed (up to 2000 fps, depending on model and operational mode), the high intrinsic resolution of 100 µm and their ability to handle the high count rates that typically occur in medical applications such as CT.

The flexibility in size (currently from 12.8×100 mm² up to 51.2×400 mm² and beyond) and in shape (also curved/segmented versions are available) means they can be adapted to many imaging geometries. High quality manufacturing processes ensure minimal gaps between detector segments, a pre-requisite for the very high image quality demanded by medical research applications.

The ability to resolve X-ray photon energies with two embedded thresholds per pixel and energy scanning by software enables tissue separation and highlighting of contrast media and other materials.



The XC-Hydra range of photon counting detectors can be operated in frame output mode for 3D, or digital TDI for scanning applications.

Photon counting technology offers outstanding efficiency and leading edge performance and the benefit of lower dose. The fast imaging speed of these detectors results in shorter acquisition time. The intrinsic sharpness of direct conversion technology through CdTe correlates to less blurring, enhancing clinical value.

Dual energy technology discriminates materials with high levels of accuracy in bone and soft tissue imaging, and this means fewer X-ray exposures for the patient. A unique modular design with multiple length variants meets individual application requirements.
