Radiation-Free Tracking and 3D Visualization of Medical Devices

Interventional procedures are typically minimally invasive, using flexible medical devices such as catheters, guide wires and needles, to perform ablations, embolizations, stent placements and more. Imaging, particularly X-ray imaging, is used to track the flexible medical device inside a patient’s body and allow for proper guidance, placement...

Active Magnetic Manipulation of Internal Organs and Tissues

Minimally invasive surgery (MIS) is a surgical procedure that typically utilizes an endoscope or other instrument which is passed through a small incision into a body. Because of this, it often results in less trauma, complications and adverse effects versus open-type surgery. It is not without challenges, however, particularly when it comes to tissue...

Non-Contact Flow Manipulation Using Magnetic Fields

MagnetoFluidDynamic (MFD) approaches are promising for controlling electrically conductive fluids, however, they have not yet been developed for control of time-dependent fluid flows in 3D. The main issue with using MFD entails solving the mathematics involved in tuning the magnetic field to achieve the desired 3D fluid flow. Despite several studies...

Bio-Inspired Robot for Tube Inspection

Tubular structures are commonly used in boilers and heat exchangers. Working under extreme conditions such as high temperatures, large stress loads, hot and high-velocity steam and pressure leads to corrosion, cracks, and stress-corrosion cracks in either the body or welded connections of these components. Regular inspection of these components...
