METHOD FOR OBTAINING BIO-IMAGE USING RESONANCE OF MAGNETIC NANOPARTICLE

摘要

The present invention relates to a method for obtaining a bio-image. The method for obtaining a bio-image according to the present invention comprises the steps of: (a) providing a magnetic nano-particle (100) having a magnetic vortex structure (110); (b) applying the first magnetic field to the magnetic nano-particle (100) so that the magnetic nano-particle (100) can have a resonance frequency; (c) applying the second magnetic field having a resonance frequency to the magnetic nano-particle (100); (d) releasing an application of the second magnetic field; (e) measuring time T1V consumed for a z-axis magnetic component of the magnetic nano-particle (100) to be restored to a predetermined ratio, or time T2V consumed for an x-axis or y-axis magnetic component of the magnetic nano-particle (100) to be reduced to a predetermined ratio; and (f) obtaining an image signal from at least one of the T1V or T2V. The present invention is designed to provide a method for obtaining a bio-image capable of obtaining an image of human beings by applying low magnetic field as compared to a conventional apparatus for obtaining an MR image. In addition, the present invention is designed to provide a method for obtaining a bio-image with higher signal sensitivity than a magnetic resonance image that can be filmed quickly.
