Owning Palette: Medical Image Controls

Requires: Biomedical Toolkit

Displays the transverse plane (X-Y), coronal plane (X-Z), and sagittal plane (Y-Z) that intersect the coordinates of 3D volume data.

User Interface Controls

You can use the following controls to navigate the 2D Viewer.

Action	Control
Zoom in	Scroll mouse wheel up
Zoom out	Scroll mouse wheel down
Drag image	Click and drag
Index images	Press the <Alt> key while you click and drag
