Claim Text:
1. A method for imaging from a distribution of magnetic small particles, the method comprising: setting the magnetizations of the magnetic small particles in a rotation using an external magnetic field of a field strength and rotation frequency rotating about a longitudinal axis (z), wherein the rotation of the magnetizations of the magnetic small particles is asynchronous with respect to the external magnetic field, wherein an asynchronous average rotation frequency dependent on the field strength results for a magnetic small particle ensemble of the magnetic small particles, applying a magnetic gradient field to impose a position dependency on the asynchronous average rotation frequency of the magnetic small particle ensemble, recording the frequency components of the superimposed transverse magnetization (M converting the recorded frequency components into spatially resolved distribution of the transverse magnetization (M determining the spatially resolved distribution of the superimposed transverse magnetization (M
