UMRAM researchers published a novel work in MRM journal in
collaborating with UNAM team. This study presents an inductively
coupled ultra-thin, flexible, and passive RF resonator for MRI marking
and guiding purposes with clinical feasibility. Standard
microfabrication processing was used to fabricate the resonant marker.
The proposed marker consists of two metal traces in the shape of a
square with an edge length of 8 mm, with upper and lower traces
connected to each other by a metalized via. A 3T MRI fiducial marking
procedure was tested in phantom and ex vivo, and then the marker's
performance was evaluated in an MRI experiment using humans. The
ultra-thin and flexible structure of this wireless flexible RF
resonant marker offers effective and safe MR visualization with high
feasibility for anatomic marking and guiding in various regions of the
