摘要：
The present disclosure relates to a susceptibility artifact reducing vacuum bag for reducing local magnetic inhomogeneity inside a magnetic resonance imaging system, the vacuum bag comprising a mixture of diamagnetic composite material made of a diamagnetic material, such as pyrolytic graphite, and a filler material, the fraction of diamagnetic composite material and filler material selected such that the mixture has a net magnetic susceptibility corresponding substantially to the magnetic susceptibility of human tissue, the vacuum bag further comprising a valve for establishing an externally generated vacuum inside the vacuum bag.
