    Abstract: The invention relates to a passive medical identification device 1 to be used for identifying a medical tool such as, for example, a surgical instrument, if the medical tool is equipped with the identification device. The identification device comprises a casing 2, a magnetic object 3 arranged within the casing such that it is rotatable out of an equilibrium orientation by an external magnetic torque, and a restoring torque provider 4 such as, for example, a further magnetic object providing a restoring torque forcing the magnetic object back into the equilibrium orientation. The magnetic object 3 rotationally oscillates upon excitation by an external magnetic torque, thereby generating a response magnetic signal which is transduced into an induction signal that can provide a fingerprint specific for the respective identification device. Accordingly, the identity of the identification device and hence of the medical tool equipped with the identification device can be determined based on the induction signal.

    Abstract: An apparatus for detecting magnetic particles in a field of view, which apparatus includes selection coils, drive coils, receiving coils configured to acquire detection signals, and a processor configured to control the coils and reconstruct an image of the field of view from the detection signals. The processor is further configured to: identify in the detection signals one or more background time periods at which no magnetic particles were present in the field of view, wherein signal time periods at which magnetic particles were present in the field of view are interspersed with at least one of said one or more background time periods; use the detection signals obtained at the background time periods to correct detection signals obtained at the signal time periods; and reconstruct the image from the corrected detection signals obtained at the signal time periods.
