1 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

2 Radiopharmaceuticals

3 NANOMAGDYE: The marker Phosphonate coupling agent stabilizes pH at 4.7 -> blood. Simple experiment for biocompatibility Synthesis with microbubbles -> ultrasound contranst agent

4 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

5 Measurements on low velocities

6 Measurements on hand movement speed

7 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!
