X-Ray Phase-contrast Imaging System ZDGX

Photon counting imaging has the technical advantage of zero noise, which makes low-light flux X-ray imaging possible. It solves the technical shortcoming that traditional detectors cannot realize phase-contrast imaging. By adopting the principle of quasi-coaxial phase-contrast imaging, it solves the problem that grating method, interferometer method, diffraction enhancement method and other methods are difficult to be applied commercially. And absorbing materials with no difference in contrast. Such as pathological section, carbon fiber, etc., to meet the clinical, scientific research, industrial and other fields of application.

Photon counting X-ray detector:

direct conversion; large imaging area; fast imaging; robust and temperature-and-humidity tolerant

• No coherent light required

• 5μm focal size with high spatial resolution

• With extremely high cost performance, strong maintainability

• The largest phase-contrast imaging area

The principle of coaxial phase contrast imaging

Using the principle of coaxial phase contrast imaging, the detector is pulled far to a certain distance, the phase difference is captured by the large imaging surface array chip, and the phase information is obtained by the intensity information back operation to obtain the phase contrast image.

High grayscale

Phase contrast images can clearly distinguish the density difference, while traditional grayscale images can hardly distinguish the contour, and the details are blurred.
