磁粒子成像(MPI)是一种对磁性粒子空间分布敏感的层析成像方式。本文描述的光谱仪能够测量超顺磁性纳米粒子的再磁化谱。利用这台光谱仪，可以表征粒子对MPI的适用性。此外，光谱仪可以用来估计颗粒尺寸分布，这使得在MPI中可以进行更准确的模拟。
Magnetic particle imaging (MPI) is a tomographic imaging modality sensitive to the spatial distribution of magnetic particles. The spectrometer, described in this paper, is capable of measuring the remagnetization spectrum of superparamagnetic nanoparticles. With this spectrometer the suitability of particles, for MPI, can be characterized. Furthermore, the spectrometer can be used to estimate the particle size distribution, which allows for more accurate simulations in MPI.
