Rendering and Positioning an Echo Image Set
Follow these steps to volume render an echo image set and accurately position it within a segmented heart model.
1. Open the Echo Image Set
Open the Controller Menu.
Select the Images tab.
Locate the image tab that contains the Echo image set and press Volume Rendering.
Open the drop-down menu and select the Echo preset.
2. Adjust the Rendered Model
You can refine the detail and appearance of the rendered model using the following controls:
Crop sliders: Adjust the visible portion of the volume.
Offset sliders: Modify the depth and position of the rendering.
3. Apply a Mask to Shape the Cardiac Valve
To refine the valve’s contours and shape:
Open the Stylus Menu.
At the bottom, find the Mask tool section.
Press Add Mask to begin shaping the rendered model.
Use the middle finger trigger on your non-dominant hand to toggle between Add Mask and Remove Mask modes.
Continue refining until the valve’s appearance is satisfactory.
4. Reposition the Valve Within the Segmented Model
Open the Controller Menu again.
Go to the Images tab and select Image Registration.
Enable the Use Free Hand toggle.
This allows you to freely manipulate and position the rendered valve within the segmented heart model.
5. Final Positioning and Alignment
Open the Images tab and disable the Clippable toggle.
Create a new clip plane that intersects the segmented heart model.
Use this plane to position the valve precisely.
For improved accuracy, align the model in relation to the CT scan using the planar surface as a reference.
