If a series contains images made with a varying step, volume reconstruction by the standard algorithm is impossible. There are two solutions to this problem.
The missing images are interpolated (recreated). In this case, the reconstruction will not be accurate. The DICOM Viewer will return a warning like Series slice distance varies too much: most unique distance: 7.5 mm; min distance: 7.5 mm; max distance: 22.5 mm. Model may be innacurate.
The reconstruction is made within the part of the series where the distances between slices are the same. In this case the reconstruction will be incomplete. The DICOM Viewer will return a warning like Series slice distance varies too much. Only slices 1-22 of 28 are used.
The ﬁrst method is used by default. For details on how to specify the preferable reconstruction method, see Section 15.6.3.
