A new magnetic resonance (MR) tracking method enhances microcoil signal robustness in low signal-to-noise ratio (SNR) conditions. This technique improves tracking accuracy for microcoils, even when inductively coupled to other MR coils.

Area of Science:

  • Medical Imaging
  • Biophysics
  • Magnetic Resonance Imaging

Background:

  • Active MR tracking of microcoils is crucial for various medical applications.
  • Low signal-to-noise ratio (SNR) conditions present a significant challenge for robust tracking.
  • Conventional methods struggle with microcoil orientation and external signal interference.

Purpose of the Study:

  • To develop and validate a novel strategy for enhancing the robustness of active MR tracking of microcoils.
  • To improve microcoil tracking performance specifically under low SNR conditions.
  • To enable reliable tracking of microcoils regardless of their orientation or inductive coupling.

Main Methods:

  • Implemented dephasing magnetic field gradient pulses orthogonal to the frequency-encoding gradient.
