Inverse Problems Lecture 7/2017: computational model for 2D tomography 2/5

Teaching my course "Inverse Problems" at University of Helsinki.
The lecture was given at February 8, 2017.

Explanation of the three crucial concepts in a practical inverse problem:
(1) the measurement vector coming from a device,
(2) "continuum model" for the physical quantity of interest,
(3) "computational model" approximating the unknown and the measurement process
