Problem addressed

In magnetic robot-assisted surgery, precise localization of in-vivo devices is crucial for success, closed-loop control, and autonomy. Current wireless systems lack sufficient working space, hindering real-time feedback and increasing surgical complexity. This limitation complicates procedures for surgeons and robotic systems alike.

Innovation

The system innovatively employs a reconfigurable sensor array design, achieving high adaptability to various human body sizes in clinical settings.
By flexibly combining multiple sensor arrays, the system provides a measurement space that meets the requirements of different human body sizes.

Key impact

Compared to traditional methods, this system offers a radiation-free localization solution.
The system utilizes the intrinsic magnetic properties of the device for localization, eliminating the need for additional active electronic components.
The system can directly calculate the spatial position and orientation of magnetic devices based on magnetic field data.
