This technology is a high-resolution tracking system for labeled intracorporeal devices using magnetic resonance imaging (MRI).
MRI is frequently used to track the position of and guide devices that are inserted into the body as part of medical procedures and surgeries. However, existing technologies rely on active or passive tracking techniques that have significant drawbacks and offer poor results. Passive techniques rely on subtle signal artifacts and offer poor signal to noise ratios, while active techniques require cumbersome electrical wires that can compromise safety.
This technique enables accurate wireless tracking of labeled medical devices using MRI. For rapid image acquisition and real-time device tracking and guidance, this system detects the unique MR signals emitted by magnetically active atoms in the label such as fluorine. This signal is detected separately from the hydrogen signal that is used to create the image, providing a clear visualization of the device without distorting the surrounding anatomy. This allows for wireless real-time tracking of medical devices in the body without sacrificing signal to noise ratio or resolution.
A prototype of the technology has been tested and shown to be effective.
