Area of Science:

  • Medical Imaging Technology
  • Surgical Navigation Systems
  • Human-Computer Interaction

Background:

  • Surgical procedures often require frequent access to patient imaging data, such as computed tomography (CT) scans.
  • Traditional methods of interacting with medical imaging software during surgery can disrupt workflow and compromise sterile fields.
  • There is a need for intuitive and non-invasive control methods for medical imaging software in operating rooms.

Purpose of the Study:

  • To evaluate the effectiveness of the Dr. aeroTAP, a novel touchless display system, for controlling medical imaging software during surgery.
  • To compare the performance of the Dr. aeroTAP system against a conventional mouse interface for surgical imaging tasks.

Main Methods:

  • The Dr. aeroTAP system was developed to interpret hand gestures in the air, translating them into virtual mouse events.
  • Comparative analysis involved measuring task completion times for selecting 3D images from thumbnails (Study 1) and viewing CT images on a DICOM viewer (Study 2).
  • The study included five surgeons across 31 hepato-biliary operative procedures, comparing the Dr. aeroTAP with a standard mouse.

Main Results:

  • The Dr. aeroTAP system demonstrated statistically significant reductions in time for image selection compared to the mouse (P < 0.001).
  • Significant time savings were also observed when using the Dr. aeroTAP for displaying CT images on the DICOM viewer (P < 0.001).
  • All participating surgeons showed improved performance with the touchless interface.

Conclusions:

  • The Dr. aeroTAP touchless interface is an efficient tool for surgical imaging observation.
  • The system allows for seamless interaction with medical imaging software while maintaining a sterile surgical field.
  • Gesture-based control of medical imaging enhances surgical workflow and efficiency.
