Advantages Of Phase Contrast: A Few Examples
inCiTe™ is a world-first phase-contrast benchtop micro-CT. Using KA Imaging patented technology, this X-ray microscope excels at imaging materials that have poor X-ray absorption, such as biomaterials, polymer composites and other low-density samples. inCiTe is also the first commercial micro-CT to utilize BrillianSe™, the highest spatial resolution direct conversion X-ray detector in the world for hard X-rays, that allows for true unmagnified resolution down to 8μm.
Why phase-contrast?
When an object is placed in front of an X-ray source, the shadows, or projections, of the object can be captured by a detector in the background. Computed tomography, also known as CT, is the process of reconstructing an image representation of the object from its X-ray projections using computer algorithms.
The primary advantage of the phase-contrast paradigm is that when an object presents poor conventional absorption-contrast (e.g. soft biological tissue or other low-density materials such as polymers), contrast can instead be generated with higher sensitivity using phase-contrast techniques.
inCiTe™ achieves phase-contrast directly by free-space propagation of the X-ray beam, transforming X-ray phase changes due to the object into X-ray intensity variations at the detector.
The result is an image with much more detail, which wouldn’t be possible using conventional CT techniques.
