A method of producing a test body for diffusion tensor imaging, which comprises a plurality of channels in a structuring material, the channels preferably having a maximum cross-section of 625 μm, wherein a virtual model of the test body is created and the virtual model is fed to a structuring device which produces the test body by means of a 3D printing-based, in particular lithography-based, structuring process, the structuring process being designed as a multiphoton lithography process, in particular as a multiphoton absorption process, in which the structuring material containing a photosensitizer or photoinitiator is irradiated in a location-selective manner, wherein the radiation is successively focused on focal points lying within the structuring material, resulting in that in each case a volume element of the material located in the focal point is subjected to a change in state by means of a photochemical reaction as a result of multiphoton absorption.

A method for transcranial magnetic stimulation (TMS) of a stimulation area of medical interest, combined with functional magnetic resonance imaging (fMRI) for visualization of the response of, for example neurons, is disclosed. An ultra-thin magnetic resonance coil, MR coil, positioned in the immediate vicinity over an area where the response of, for example neurons, is to be detected, and preferably sandwiched between the TMS coil and the area, provides an excellent signal-to-noise ratio. The TMS can be performed directly through the MR coil. A great deal of flexibility in the number of the TMS and MR coils in use and their spatial arrangement is provided. A corresponding system for the TMS/fMRI studies is also provided.
