STUDY OF THE FLUXSET MAGNETIC PROBE SPEED–SENSITIVITY DEVELOPED FOR DETECTION OF MAGNETIC NANOPARTICLES IN SURGERY

摘要

Markers for imaging are vital parts of surgical processes. Sudince radioactive compound pose considerable risk to bothudthe recipient and the surgical staff, alternative marking teudchniques are of interest. In NANOMAGDYE project, magneto-udoptically active nano-particles were created for this reasudon. The detection of the magnetic interaction of low mass nanudo-udparticles in surgical environment is very challenging; so fudar only quasi-stationary measurements were taken. This papuderudshows a measurement setup for measurements with continuousudly moving probe at lower velocities (5–10 mm/s) and at handudmovement velocity (20–30 cm/s). It was found that at the veloudcity of hand movement there is only probe response amplitudeudreduction of at most 10–15 % of the original amplitude. Theseudresults indicate that the probe used for the detection of theudnano-particles is sufficient to be used in practical purposesudin surgery.
