Magnetic particle imaging device, magnetic particle imaging method, and storage medium storing magnetic particle imaging program

Abstract

An MPI device generates projection data of a magnetization change based on a position of an FFL region in a scanning direction and an angle of the FFL region in a rotation direction, generates corrected projection data by performing sensitivity correction on the projection data by using a system function previously acquired for each piece of projection data, and generates a magnetic nanoparticle image by performing image reconstruction on the corrected projection data. When generating the system function, processing circuitry makes a linear zero magnetic field generation coil form the FFL region in a structure as a subject and scan, rotate, or scan and rotate the FFL region, makes an excitation magnetic field application coil apply an excitation magnetic field to a magnetic field region, makes a detector detect the magnetization change in the structure, and generates the system function in regard to each piece of projection data.
