Method for electronic calibration of magnetic particle imaging system

Abstract

A method for electronic calibration of a magnetic particle imaging system is provided by proposing a coded calibration scene that contains multiple nanoparticle samples distributed randomly or pseudo-randomly inside a volume of the coded calibration scene where nanoparticle positions are changed virtually multiple times to create different calibration scenes. Virtual effect is created with current carrying electromagnets surrounding the nanoparticle samples. The method comprises: placing a plurality of nanoparticle samples inside a calibration scene; surrounding the plurality of nanoparticle samples with one or more electromagnets; applying a current to the one or more electromagnets to cause a magnetic field offset at a desired amplitude to virtually move the plurality of nanoparticle samples to a desired position; generating a system matrix with compressed sensing methods by using measurements taken for different current excitations of the one or more electromagnets, wherein the plurality of nanoparticles samples are virtually in different positions.
