​
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:
PresetWindowLevelUse
Bone2000500Cortical and cancellous bone
Soft Tissue40050Muscles, tendons, ligaments
Lung1500-500Not typically used in orthopaedics

​
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
All measurement annotations and planning data are visible in stack view. Annotations are tied to specific slices and appear as you scroll to the relevant position.
