A patient model may be unclear, noisy, or cluttered for various reasons. Solutions are available to improve the visualization of this model. The following steps are recommended to optimize visualization of the model:
1. Check the volume of interest.
First, check whether the patient model can be improved by adjusting the volume of interest.
2. Cut away redundant parts.
When parts of the generated volume are redundant and/or cluttering the view, they can be removed with the Patient Mask action.
3. Apply a different transfer function.
Apply a different transfer function to the patient model to determine whether this results in a better visualization of the patient model. Select a different template option in the Transfer Functions gallery
4. Adjust the applied transfer function.
Check whether an appropriate isovalue was set. When too many objects are converted into a patient model, use the level/window action on the 3D viewer to change the isovalue threshold and to change the range of used values. The model will change accordingly in real time.
If it is not possible to get a good visualization result by adjusting the level/window tool, use the edit transfer function to obtain the desired visualization.
5. Use the Erase Bone Artifacts action
When multiple artifacts obstruct a clear view of the patient model, it is best to remove the artifacts, which will allow for optimal diagnostic viewing and/or presentation. If cutting off the redundant parts with the Patient Mask action did not suffice, continue cleaning up the model using the Erase Bone Artifacts action.
6. Smoothing the patient model
When a lot of noise is present, you can try to smooth the model by increasing the radius.
