Stack View

Stack view displays a single DICOM slice at a time, allowing you to scroll through the imaging series sequentially. This is the default view when you first load DICOM data.

​
Scrolling Through Slices

Use the mouse scroll wheel to move through slices:
  • Scroll up — move towards the head (superior)
  • Scroll down — move towards the feet (inferior)
The slice indicator in the status bar shows your current position (e.g., Slice 128 / 256).
Hold Shift while scrolling to jump 10 slices at a time. This is useful for quickly navigating through large CT series with hundreds of slices.

​
Window / Level

Window and level controls adjust the brightness and contrast of the displayed image, which is essential for differentiating between tissue types. To adjust window/level:
  1. Right-click and drag on the viewport.
  2. Drag horizontally to adjust the window (contrast).
  3. Drag vertically to adjust the level (brightness).
Common presets are available in the toolbar dropdown:

​
Slice Indicator

The slice indicator at the bottom of the viewport displays:
  • Current slice number and total slice count
  • Slice thickness (mm)
  • Series description from the DICOM metadata

​
Zoom and Pan

  • Scroll wheel click + drag — pan the image
  • Ctrl + scroll wheel — zoom in and out

​
Switching Series

When multiple DICOM series are attached to a case, a Series section appears in the properties panel. Click any series to switch the Stack view to that series. Each series maintains its own independent set of annotations. See Loading DICOM Files for details.
All measurement annotations and planning data are visible in stack view. Annotations are tied to specific slices and series — they appear as you scroll to the relevant position.
