论文摘要
使用MRI估计磁化率取决于颠倒易感性与测量的Larmor频率之间的正向关系。但是，易感性拟合中通常被忽视的约束是Larmor频率仅在样品内测量，并且在背景磁场去除后，易感源只能驻留在同一样品中。在这里，我们测试会计在易感性拟合中对这种影响的影响，并证明不应忽略这种影响。
Estimating magnetic susceptibility using MRI depends on inverting a forward relationship between the susceptibility and measured Larmor frequency. However, an often-overlooked constraint in susceptibility fitting is that the Larmor frequency is only measured inside the sample, and after background field removal, susceptibility sources should only reside inside the same sample. Here we test the impact of accounting for such effects in susceptibility fitting and demonstrate that such effects should not be ignored.
