Multiplanar reformation of a cadaver measurement in the spine region using two interspinal distraction implants for fixation of the lumbar vertebra (angular increment = 0.6°, acquisition angle = 220°) (C0/W1000). (a) Original transversal, (b) one-dimensional (1D) linear interpolation (LI) transversal, (c) three-dimensional (3D) LI transversal, (d) original coronal, (e) 1D LI coronal, (f) 3D LI coronal. Aliasing artefacts caused by small metallic objects are completely corrected, the introduction of new artefacts is not visible. Arrow 1 indicates the unobscured visibility of the two interspinal distraction implants used for fixation. Arrow 2 shows the decreased darkening next to the implant when using 3D LI compared with 1D LI.
