Visualization of needle access pathway and a five-DoF evaluation

Area of Science:

• Medical Visualization
• Surgical Planning
• Human-Computer Interaction

Background:

• Needle access pathway planning is crucial for volumetric organ surgeries.
• Existing systems primarily focus on usability and target accessibility.
• Visualization's impact on insertion quality remains under-explored.

Purpose of the Study:

• To develop an evaluation framework for needle access pathway visualization.
• To analyze the influence of visualization on surgical insertion accuracy.
• To propose an improved visualization technique for better surgical guidance.

Main Methods:

• Developed an all-round evaluation framework integrating human motion and computer graphics.
• Quantitatively analyzed visualization illustrativeness across five degrees of freedom.
• Introduced a novel visualization technique emphasizing placement and orientation.

Main Results:

• Visualization methods significantly impact needle insertion accuracy.
• The proposed technique effectively conveys crucial placement and orientation information.
• Enhanced visualization led to demonstrably higher insertion quality.

Conclusions:

• Visualization is a critical factor in surgical needle insertion performance.
• The novel visualization technique improves the conveyance of pathway orientation.
• This approach enables more accurate and higher-quality surgical insertions.
