Abstract:
Terahertz tomography is an imaging modality that is used mainly in
nondestructive testing to reconstruct the complex refractive index of an
object to detect defects or to characterize a material.
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 flow.
Mathematically, these imaging modalities require the solution of inverse
problems that can be treated as parameter identification problems. In the
talk, both imaging methods are introduced and the underlying inverse problems
will be discussed.
