What do you like about this subject?

It reveals the internal sections of the object by approximation using measured projections data.

What do you still hope to achieve/learn in this field?

Ridgelet transforms usage for approximation of inverse Radon transform.

Something interesting about this subject that others may not know:

CT scanning is an inverse problem that is ill-posed. Mathematically, infinite number of projections are required to find the exact Radon transform.

Something controversial or provocative about this subject

Heavy computational load that is unavoidable.
