Results
All participating IRs said they were seriously interested in the planning-UI.
Three participants already expressed their desire to clinically test the UI: “I would also like to,
at the proper time,
to put it into practice”.
IRs mainly appreciated:
1. The possibility to view and interact with 3D digital information.
IRs said it made it easier to understand the anatomy,
distances,
possibilities and constraints and to select the proper trajectory and stent.
2. The UI’s potential to generate 2D planes which could make the current procedure less invasive and complex.
The main critiques given was that:
1. IRs found it difficult to spatially orientate the different planes within the patient’s body.
They recommended to add more support to spatially orientate.
Examples given to do so were the availability of CT images and a representation of the US probe in relation to the patient’s body.
2. IRs were not satisfied with the available US dataset and the proposed trajectory options.
It was expressed that the dataset did not properly visualize the portal vein and the proposed trajectories were sometimes unsuitable. An IR said that for an optimal trajectory the systems should know the anatomy of the veins.
Two others said that the trajectory should allow IRs to creates a smooth and spacious intrahepatic curve with the needle.
