Modified Level Set Method

Summary: Tomography means reconstructing the internal structure of a physical object using the X-ray images of the object taken from different directions. Mathematically, the problem is to recover a non-negative function f(x) from a collection of the line integrals of f. Here we show how to solve a dynamic tomography (more…)
