 \chapter{Introduction} 
-Computed Tomography is the process of taking projection of X-ray data
-though and object and using sophisticated mathematics to estimate
-information about the interior of that object.
+Computed Tomography is the process of acquiring X-ray data (projections)
+though an object and then using mathematics to reconstruct the interior
+of that object.
