MRI-Endoskop:
NMR-Spektroskopie und MRI
PD Dr. Frank Volke Magnetic Resonance
• MRI-Endoskop (endoluminal) Cooperation: Univ.-Heidelberg/MR Inside
• Foldable coil, stabilization, positioning via optical channel, works with Siemens 1,5 T clinical Scanner. Very good homogeneity and resolution (compare MRI Image and microscope Image)

Quo vadis ?
•Miniaturization!!!
•Combination of MR with Complementary Methods
(US,Laser, IR, OCT)
•Micro-flow Imaging
•Lab-on-chip (Micro-coils)
•Broad range of composite materials, incl. organic ones: e.g.
•Cryobiology, Hydration
•Biofilms, Surface characterization
•Drug-encapsulation
