A261 Comparative verification of control methodology for robotic interventional neuroradiology procedures

<h3>Introduction</h3> Robotics is increasingly used in interventional radiology (IR), typically controlled via button presses or joysticks. <h3>Aim of study</h3> This study evaluated how different human-robot interfaces affect performance in endovascular procedures using IR simulations. <h3>Method</h3> Nine participants completed a navigation task on an IR simulator using three types of human-computer interfaces. A simulation profile of vessels, catheters, and guidewires was developed using Simulation Open Framework Architecture. A bespoke haptic controller, designed to mimic IR devices, was manufactured for robotic system control. Performance was assessed using navigation time, incorrect catheterisations, catheter and guidewire prolapses, and vessel wall forces. Participants also completed a questionnaire on controller perception. <h3>Results</h3> The device-mimicking controller outperformed joystick controls in navigation time, incorrect catheterisations, and catheter/guidewire prolapses. Qualitative feedback confirmed a preference among IR users for the device-mimicking controller. <h3>Conclusion</h3> Three of four performance metrics demonstrated that a device-mimicking controller is better suited for robotic control in interventional neuroradiology than joystick-based interfaces. <h3>Conflict of Interest</h3> No
