Method for visualising a region of interest inside an examination object into which an examination instrument has been introduced, the method being performed by means of a tomosynthesis system, wherein the introduction is not included by the method according to the invention, wherein the method comprises at least the following steps: - acquiring raw datasets from a number of lateral acquisition angles (A1, A2, A3,..., A6), wherein acquisition angles in a range around a central axis are omitted and the examination instrument is arranged in the vicinity of the central axis, whereby a blocking of a beam path by the examination instrument is avoided, wherein the raw datasets are acquired at acquisition angles (A1, A2, A3,..., A6) of at least 10°, preferably at least 15°, to a central axis, - calculating a number of synthetic projections from the raw datasets, wherein the synthetic projections are reconstructed directly from the raw data, or wherein the calculating comprises a reconstruction of a volume dataset or individual thin slices from the raw data and a forward projection of the volume dataset or the thin slices on a virtual detector, and - outputting the synthetic projections in the form of an image sequence which represents the examination object in a rotating visualisation, wherein the synthetic projections are merged in the image sequence in such a manner that, when the image sequence is run or played back, the impression is created in an observer that the visualised examination object is rotating. wherein the introduction is not included by the method according to the invention, wherein the method comprises at least the following steps: - acquiring raw datasets from a number of lateral acquisition angles (A1, A2, A3,..., A6), wherein acquisition angles in a range around a central axis are omitted and the examination instrument is arranged in the vicinity of the central axis, - acquiring raw datasets from a number of lateral acquisition angles (A1, A2, A3,..., A6), wherein acquisition angles in a range around a central axis are omitted and the examination instrument is arranged in the vicinity of the central axis, whereby a blocking of a beam path by the examination instrument is avoided, wherein the raw datasets are acquired at acquisition angles (A1, A2, A3,..., A6) of at least 10°, preferably at least 15°, to a central axis, - calculating a number of synthetic projections from the raw datasets, - calculating a number of synthetic projections from the raw datasets, wherein the synthetic projections are reconstructed directly from the raw data, or wherein the calculating comprises a reconstruction of a volume dataset or individual thin slices from the raw data and a forward projection of the volume dataset or the thin slices on a virtual detector, and - outputting the synthetic projections in the form of an image sequence which represents the examination object in a rotating visualisation, - outputting the synthetic projections in the form of an image sequence which represents the examination object in a rotating visualisation, wherein the synthetic projections are merged in the image sequence in such a manner that, when the image sequence is run or played back, the impression is created in an observer that the visualised examination object is rotating.
