  • Method for magnetic particle imaging having unlimited axial field of view
    Patent number: 10338161
    Abstract: The invention relates to a method and an MPIS scanner for tomographic imaging of an object with magnetic particles distributed in the interior of the object, comprising the steps of generating a selection magnetic field with a predetermined magnetic field gradient in at least one field-free point (FFP) in a predetermined scanning plane, generating a time-dependent, periodic excitation magnetic field with a predetermined maximum frequency, repeatedly displacing the at least one FFP along a predetermined closed trajectory with a predetermined repetition time in the scanning plane, moving the object through the scanning plane along a predetermined advance direction with a predetermined advance speed, detecting the change in the magnetization state of the magnetic particles at the points in the object interior through which the at least one FFP passes, reconstructing the local particle concentrations at the points through which the at least one FFP passes in respect of an object coordinate system, interpolating t
