Development of measurement procedure for the application of magnetic nanoparticles in surgery Datz Dániel Tutor: Antal Gasparics PhD Pázmány Péter Catholic University Faculty of Information Technology
NANOMAGDYE: The marker Phosphonate coupling agent stabilizes pH at 4.7 -> blood. Simple experiment for biocompatibility Synthesis with microbubbles -> ultrasound contranst agent
NANOMAGDYE: The probe Magnetic and optical sensor built together Fluxset sensor: soft magnetic core, two coils: driving and pickup coil No intrinsic magnetic field: excited with a third coil: excitation coil Nanoparticles need very strong excitation: differential excitation
Measurements on low velocities
Measurements on hand movement speed
Conclusion At low velocities there are no significant distorting effects At higher velocities the distorting effects are at most 10-15% of the maximum amplitude The probe is completely capable of the measurements it was designed to do Simulation of the measurements Algorithm for signal source localization Thank you for your attention!
