Area of Science:

  • Medical Imaging
  • Human-Computer Interaction
  • Radiological Technology

Background:

  • Interventional radiology image manipulation relies on communication between radiologists and technologists.
  • Current methods using mice or consoles can lead to communication errors and inefficiencies.
  • Developing intuitive control systems is crucial for optimizing radiological procedures.

Purpose of the Study:

  • To evaluate the efficacy of an eye tracker system for manipulating angiographic images.
  • To compare the performance of an eye tracker system against conventional mouse control.
  • To assess the potential of eye tracking to reduce communication errors in interventional radiology.

Main Methods:

  • An eye tracker system was developed to calculate gaze position and fixation on angiographic displays.
  • Fourteen radiological technologists performed image manipulation tasks for five common angiography cases.
  • Task completion times were recorded for both eye tracker and mouse control methods.

Main Results:

  • The eye tracker system significantly reduced image manipulation time compared to the mouse (10.4s vs 16.9s, p<0.001).
  • Participants completed tasks more efficiently using the eye tracker.
  • Statistical analysis was performed using Excel and R Studio.

Conclusions:

  • Direct manipulation of angiographic displays via eye tracking is feasible for radiologists.
  • The eye tracker system offers a potential solution to minimize communication errors.
  • This technology can enhance efficiency in interventional radiology workflows.
