Harmonic-Aware Transformer for Real-Time Catheter Localization in Interventional Procedures of Magnetic Particle Imaging
arXiv:2607.02919v1 Announce Type: cross Abstract: Magnetic particle imaging (MPI) enables real-time, radiation-free tracking of magnetic nanoparticle-coated instruments, making it highly suitable for interventional procedures. This study proposes a harmonic-aware transformer framework that directly predicts catheter tip positions from raw MPI voltage signals, eliminating the need for image reconstruction and reducing computational latency. The framework incorporates frequency-domain preprocessing to isolate the 2nd to 8th drive-field harmonics, enhancing the signal-to-noise ratio while preserv
The convergence of advanced imaging techniques with real-time AI processing is accelerating due to improved computational efficiency and the demand for less invasive medical procedures.
This development significantly enhances precision and safety in interventional medical procedures, reducing reliance on radiation-emitting technologies and improving patient outcomes.
Medical interventions can now leverage radiation-free, real-time, highly accurate instrument tracking, leading to operational improvements and potentially broader accessibility.
