Terahertz tomography is an imaging modality that is used mainly in

nondestructive testing to reconstruct the complex refractive index of an


Magnetic particle imaging, on the other hand, is a novel technique that

is used in medical imaging. Here, magnetic nanoparticles are injected

into the blood stream. Their response to external applied magnetic

fields is measured and the concentration of the particles is

reconstructed to gain information on, e.g., the blood stream.

Mathematically, these imaging modalities require the solution of inverse

problems that can be treated as parameter identification problems, which

will be discussed in the talk.
