METHOD AND APPARATUS FOR MAKING QUANTITATIVE MEASUREMENTS OFLOCALIZED AACCUMULATIONS OF MAGNETIC PARTICLES |
摘要 |
Apparatus for quantitatively measuring groups of magnetic particles. The particles are complexed with substances to be determined and are excited in a magnetic field. The magnetic particles (11) are thereby caused to oscillate at the excitation frequency in the manner of a dipole to create their own fields. These fields are inductively coupled to sensing coils (43) fabricated in a gradiometer configuration. The output signals from the sensing coils are appropriately amplified and processed to provide useful output indications. |
