“Computed Tomography: a real case example of inverse problem”

Abstract
X-ray computed tomography (CT) is a well known medical imaging technique, that seeks to reveal internal structures hidden by the skin and bones. Mathematically, the CT process can be modelled as a linear system and the image reconstruction is a challenging inverse problem. In this talk I will show both phisical and mathematical basic concepts, to explain the CT process, and the two possible approaches to solve the problem (leading to analitical or iterative numerical methods). Finally, I will shortly introduce the Digital Breast Tomosynthesis (DBT) technology, that is a 3D emerging technique for the diagnosis of breast tumors, together with numerical results for a simulated problem.

Rif. int. C. Marastoni, T. Vargiolu

At 16:30, a little after the talk of Elena Morotti ending this 2015/16 season of Seminario Dottorato, a refreshment will be offered at the common room of the 7th floor. Everyone is cordially invited.
