Magnetic Particle Spectroscopy

Magnetic Particle Spectroscopy (MPS) is a new measurement method related to Magnetic Particle Imaging (MPI). In MPS a sinusoidal signal is applied to the sample. Due to the non-linearity of the magnetization curve of the sample, the acquired signal contains higher harmonics. The magnetic characteristics of the sample can be calculated by this information. Hence MPS has become a standard method for characterizing and optimizing magnetic particles that are used either for MPI or Magnetic Resonance Imaging (MRI).

 

Our MPS software can perform simple "one-button" experiments as well as highly advanced measurements. Experienced users can access and change all parameters individually. Besides the automatic report generation for each measurement it is possible to access the acquired raw data.
