Lecture 8 (January 28, 2015) 

Construction of X-ray measurement matrices using Matlab's built-in function radon.m. Naive reconstruction from data with inverse crime. Also: truncated SVD reconstructions from data with inverse crime. Book sections 2.3.4, 2.3.5, 4.2 and 4.4.3.

Lecture 9 (January 30, 2015) 

Two demonstrations of current research in X-ray tomography reconstruction methods.

 Lecture 10 (February 3, 2015)
