Methods and materials
From an acquired 3D US dataset,
a 3D US based UI was designed (figure 1): 1) on the right,
the 3D view of the segmented hepatic and portal vein images are visualized; 2) on the left,
a 2D axial section plane is visualized.
The mouse allows IRs to scroll through the dataset in the axial direction and to zoom or rotate the segmented images.
The mouse also allows IRs to select the preferred target point/area in the portal vein (figure 1) and the preferred hepatic vein to target from (figure 2).
Based on the selection,
the system calculates and presents three possible puncture trajectories (figure 3).
It also shows accompanying distances,
such as the distance between the exit point in the hepatic vein and the entry point in the portal vein.
The IRs are able to study the different trajectory options and to select a suitable one.
After selecting one,
IRs can view the chosen trajectory in the longitudinal and cross section of the veins and in the 3D US image.
Five IRs were asked to use the planning-UI and to plan and select a desired trajectory,
view the created planes and provide feedback.
