Augmented visualization with depth perception cues to improve the surgeon's performance in minimally invasive surgery

Area of Science:

• Medical technology
• Surgical innovation
• Computer-assisted surgery

Background:

• Minimally invasive surgery offers benefits like reduced hospitalization and fewer complications.
• Surgeons face challenges with restricted vision and 2D imaging in minimally invasive procedures.
• Current methods require surgeons to mentally correlate pre-operative scans with the surgical field.

Purpose of the Study:

• To develop and evaluate an augmented reality navigation system for minimally invasive surgery.
• To provide surgeons with enhanced visualization of internal anatomy and depth information.
• To improve surgical precision and reduce the risk of damaging critical structures.

Main Methods:

• Development of a navigation system for pre-operative and intra-operative phases.
• Implementation of an augmented reality system superimposing virtual organs onto the patient's body.
• Integration of visual and audio cues to guide surgical actions.

Main Results:

• The system demonstrated good efficacy and accuracy in test scenarios.
• Augmented visualization provided surgeons with an "X-ray vision" of internal anatomy.
• Operating room tests indicated a need for improved tracking system robustness against occlusions.

Conclusions:

• Augmented reality systems can significantly enhance minimally invasive surgery.
• The developed system aids surgeons by overlaying virtual anatomy and providing depth cues.
• Further refinement of tracking systems is necessary for real-world clinical application.
