The Ultrasound Modes

 

These modes are used to create 3D polygonal volumes out of 3D ultrasound datasets.

 

Note:

 

These modes are only abailable if you have a compatible CUDA GPU in your system.

 

SliceOmatic is able to work with 3D ultrasound datasets in either Cartesian, cylindrical or spherical system. To work with these, the program will first re-slice the volume in square voxels in a Cartesian system.  That volume is then filtered and then  thresholded.  The user can then work on this volume to increase/decrease the voxels values or directly mask the voxels to edit the re-constructed polygons of the geometry. The resulting polygonal model (or simply the re-slice voxels) can then be exported from the "File" menu using geometry tokens.

 

The available modes are:

 

 

•Filter

Ultrasound images are noisy!  This mode enable you to filter the data using a 3D convolution filter.

 

•Threshold

The "Threshold" Mode enable you to fix the base threshold value used to create the geometry.

 

•Rotate

The "Rotate" Mode is used to re-sample the volume after having rotate it.  This enable you to align the model on the X, y and Z axis.

 

•ROI

The "Region Of Interest" Mode is used to limit the visualization/sculpting to a sub set of the volume using clip planes in X. Y and Z.

 

•Sculpt

The "Sculpt" mode is used to edit the volume and create clean 3D models from your dataset.

 

•Cleanup

The "Cleanup Mode" is used to mask unconnected parts of the geometry.

 

•Hole Filling

The "Hole Filling" mode is used to fill out holes inside the geometry.  It is a useful step before the "Optimize Media" step.

 

•Optimize Media

The "Optimize Media" Mode is used to empty out the interior of closed geometries.  This enable you to create 3D volumes with less material.  However, an empty geometry is more fragile, so this mode can also be used to create a "filling" mesh to make the object more rigid.

 

•VR Sculpt

The "VR Sculpt" Mode is used to edit the 3D geometry in VR.

 

•VR Volume

The "VR Volume" Mode is used to visualize the volume in VR.

 

Note:

 

The VR modes are only abailable if you have a compatible VR headset plugged-in.

 

 

 

 

From the Keyboard

 

There are a few keyboard keys that have been mapped to commands that can be used in all the TAG modules.

Technical Note:

 

The "Flood-fill" operation: All the pixels adjacent to the pixel under the cursor and having the same TAG value will be filled by the current TAG value.

 

 

From the Command Line

 

A number of commands affect the tags. These can be found in:

"SliceO_System\Brush.dll" section of Appendix B.

"SliceO_System\Tag.dll" section of Appendix B.
