Evaluation of a Touchless Angiography Suite Computer Controller for Neuroendovascular Procedures

Area of Science:

• Medical technology
• Neurosurgery
• Medical imaging

Background:

• The GestSure system is an FDA-registered, depth-sensing infrared device.
• Initially developed for touchless image navigation during open surgery.
• Its feasibility in neuroendovascular procedures using intracranial aneurysm coiling cases was unexplored.

Purpose of the Study:

• To explore the feasibility of the GestSure system for neurointerventionalists.
• To assess the learning curve of the gestural interface across different medical training levels.
• To evaluate the system's utility in manipulating angiographic images for aneurysm coiling.

Main Methods:

• Prospective cohort study comparing standard keyboard/mouse with the gestural interface.
• Involved 4 medical students, 6 residents, 6 fellows, and 5 staff neurointerventionalists.
• Training focused on gestures for 3D software functions; testing used real patient cases.

Main Results:

• High learning rates for specific tasks: 71.4% for LAO30, 80.9% for aneurysm neck, 76.2% for parent vessel.
• Staff neurointerventionalists showed greater consistency than trainees.
• Significant learning effect observed across all expertise levels, with fastest learning in staff.

Conclusions:

• Touchless angiography suite control using a gestural interface is feasible for neuroendovascular procedures.
• The GestSure system is rapidly learned by medical professionals at all training levels.
• The technology demonstrates potential for improving image manipulation in endovascular treatments.
