Using Intense Synchrotron Radiation to Produce Higher-Quality CT Images

Several people would have undergone a CT scan at a certain point in their life—sliding in and out of a tunnel, with a huge machine rotating around. X-ray computed tomography, well-known by its acronym CT, is a technique extensively used to capture cross-sectional images of objects.
