Conventional CT measure how much of the x-rays are attenuated by the phantom the x-rays pass through. However, different materials (even with the same density) attenuate different energy photons differently, which is not captured by conventional CT .
Spectral CT measures how specific x-ray energy are attenuated, which is used to determine material composition. Then we can give color to the reconstucted image
Multi-Source CT Systems
Multi-source stationary CT imaging is a type of computed tomography (CT) that uses multiple or distributied X-ray sources to get the infomation about phantom.
It improve the stuctural freedom and the time resolution, and provide more imformation from the inside of objects.
Intelligent Physics, Algorithms, and More
When we get the data from the CT platform, we need to process the data by some algorithms or modeling.It’s bad to do reconstuction or analysis using unprocessed CT data.
By using some advanced and intelligent algorithms, we can quickly and accurately to do physical model analysis, scatter correction ,reconstuction, and more.
