The invention relates to a method for imaging from a distribution of small magnetic particles. According to said method, the magnetisation of the small particles is rotated asynchronously to the magnetic field by means of an outer magnetic field of suitable field intensity and rotational frequency, which rotates about a longitudinal axis (z), whereby an asynchronous average rotational frequency is generated for a set of particles according to the field intensity; a spatial dependence is impressed on each set of particles by means of a magnetic gradient field of the asynchronous average rotational frequency; the frequency parts of the superpositioned transverse magnetisation (MQ) of the set of particles are detected; and a spatially resolved distribution of the transverse magnetisation (MQ) determines the small particles and emits same by means of the frequency parts. The invention also relates to a suitable device. An improved spatial resolution can be obtained, compared to the previous magnetic particle imaging methods, with essentially lower field intensities.
