How to Scan a CAT: 
The Mathematics of Computed Tomography


ABSTRACT:
Most people are familiar with the concept of a CAT scan, or have even experienced one themselves. What is much less well known is that there
is a lot of mathematics involved. A CAT scanner is not some kind of fancy camera; the image is computed, pixel by pixel, from thousands of measurements.

In this talk, I will given an overview of the underlying physics, the resulting mathematical problem, and the numerical methods for solving the problem.
