3D · MPR · MIP & more

Volumetric tools work best on cross-sectional series with enough slices (CT / MR / PET, ~10+ images). Open these from the toolbar; each has a keyboard shortcut and toggles back to the normal grid.

Modes

• MPR (D) — multiplanar reconstruction: axial, coronal and sagittal views with a synchronized crosshair (X).
• MIP (J) — maximum-intensity projection; great for vessels and bones.
• 3D — volume rendering of the dataset.
• PET/CT fusion (U) — overlays a PET series on CT with adjustable colormap/opacity (auto-enabled when a compatible pair is detected).
• Compare studies (H) — load layers from different studies side-by-side or fused, with per-layer transforms.
• Video / endoscopy (V) and whole-slide (WSI) (L) for the matching series types.

Crosshairs & sync

In MPR/fusion/compare, the crosshair tool (X) links the planes — move it in one view and the others follow. In the grid,sync scroll (K) keeps multiple panels aligned.

Tips

• If a mode is greyed out, the selected series likely doesn't meet its requirements (modality or slice count).
• Switching a mode off returns you to the standard view of the current series.
