Exit wave reconstruction of radiation-sensitive materials from low-dose data

Estimating radiation dose from building materials

Background: Natural radioactivity in materials under certain conditions can reach the hazardous radiological levels. So, it becomes necessary to study the natural radioactivity in different materials to assess the dose for the population in order to know the health risks and to have a baseline for future changes in the environmental radioactivity due to human activities. Materials and ...

Image Reconstruction from Incomplete Data

Spectrotemporal CT data acquisition and reconstruction at low dose.

PURPOSE X-ray computed tomography (CT) is widely used, both clinically and preclinically, for fast, high-resolution anatomic imaging; however, compelling opportunities exist to expand its use in functional imaging applications. For instance, spectral information combined with nanoparticle contrast agents enables quantification of tissue perfusion levels, while temporal information details cardi...
