Gel'fand-Graev's Reconstruction Formula in the 3D Real Space - a Framework towards a General Interior Tomography Theory
In [1-4], I. M. Gel'fand and M. I. Graev proposed inversion formulas for x-ray transforms in different spaces. In particular, Gel’fand-Graev’s inversion formula  is a fundamental relationship linking projection data to ...
Spiral Cone-beam CT - Successes with Spiral Scans
X-ray computed tomography (CT) is instrumental in medicine, industry and homeland security, which depicts internal structures of an object from its shadows projected in a fan-beam or cone-beam from an x-ray source along a ...
X-ray Grating-based Imaging - Waves Work Wonderfully
Current x-ray imaging is of critical for clinical and pre-clinical applications but it is fundamentally restricted by the attenuation mechanism. X-ray grating-based imaging represents outstanding opportunities and major ...
How to Define the Next Generation Cardiac CT Architecture? - a Contemporary Challenge for Interdisciplinary Collaboration
Cardiovascular diseases are pervasive with high mortality and morbidity at tremendous social and healthcare costs. There are urgent needs for significantly higher fidelity cardiac CT with substantially lower radiation dose, ...
