A method visualizes a tissue region. The method includes the following steps: inserting the tissue region into the capturing region of a first imaging modality, with the tissue region assuming a first shape capturing the interior of the tissue region by the first imaging modality establishing a first image volume of the interior of the tissue region when it assumes the first shape and first transforming of the first image volume into a second image volume, which represents a surface and interior regions of the tissue when the tissue region assumes a second shape.
