A new eye tracker system allows faster manipulation of angiographic images compared to traditional mouse controls. This technology can improve efficiency and reduce communication errors in interventional radiology procedures.
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.
