1. A method of producing a test body for diffusion tensor imaging, which comprises a plurality of channels in a structuring material, the channels having a maximum cross-section of 625 μm2, the method comprising:
creating a virtual model of the test body,
feeding the virtual model to a structuring device,
the structuring device producing the test body by means of a 3D printing-based structuring process, the structuring process being designed as a multi photon lithography process wherein the structuring process comprises irradiating the structuring material containing a photosensitizer or photoinitiator in a location-selective manner, wherein radiation is successively focused on focal points lying within the structuring material, resulting in that in each case a volume element of the structuring material located in a focal point is subjected to a change in state by means of a photochemical reaction as a result of multi photon absorption and in that the plurality of channels is created in the structuring material.
