​

Workspaces

The following workspaces are currently provided for user-friendly GUI.

• Quad workspace: 3 sectional views (axial, sagittal, coronal) and one 3D perspective view

• Slices workspace: 2D slice views of the medical volume are shown in slices workspace

 

Three different model representations

• Slicer: slice image interpolated with 2D texture array

• Volume: 3D volume rendering based on ray marching technique

• Isosurface: polygonal mesh extracted from 3D volumetric data using marching cubes technique

​

Sketchers

Using the following sketch tools we can measure dimensions and extract statistical information from the measured data.

• Ruler: measure the distance between two positions

• Angle: measure the angle between two segments defined by three handle points

• Rectangle: compute the mean, standard deviation, maximum/minimum, and area from the sketched rectangle

• Polygon: similar to the rectangle, but the sketched geometry is a polygon

• Freehand: similar to the rectangle, but the sketched geometry is a free-form curve

• Annotation: text message which user would like to write down
