Study Of The Fluxset Magnetic Probe Speed–Sensitivity Developed For Detection Of Magnetic Nanoparticles In Surgery

Markers for imaging are vital parts of surgical processes. Since radioactive compound pose considerable risk to both the recipient and the surgical staff, alternative marking techniques are of interest. In NANOMAGDYE project, magneto-optically active nano-particles were created for this reason. The detection of the magnetic interaction of low mass nano-particles in surgical environment is very challenging; so far only quasi-stationary measurements were taken. This paper shows a measurement setup for measurements with continuously moving probe at lower velocities (5–10 mm/s) and at hand movement velocity (20–30 cm/s). It was found that at the velocity of hand movement there is only probe response amplitude reduction of at most 10–15% of the original amplitude. These results indicate that the probe used for the detection of the nano-particles is sufficient to be used in practical purposes in surgery.
