Abstract
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.
