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 ...
SBES Advanced Multi-scale CT Facility at Virginia Tech - From Multi-scale to Multi-energy and Multi-Parameter Imaging Capabilities
While clinical CT scanners are available at our medical school, for preclinical imaging we have a Scanco micro-CT scanner, an Xradia micro-CT scanner and an Xradia nano-CT scanner. With all these scanners, we can cover ...
Development and Applications of Interior Tomography - Multi-source Interior Tomography for Ultrafast Performance
Conventional tomography allows excellent reconstruction of an object from non-truncated projections. The long-standing interior problem is to reconstruct an interior ROI accurately only from local projection segments. ...
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, ...
