摘要：
A magnetic field within a magnetic resonance (MR) imaging system (300) is measured. The MR system includes a magnet (304) with an imaging zone (308), a radio-frequency transceiver (316), and a magnetic field probe (322) located within the imaging zone. The magnetic field probe includes a fluorine sample (404) including any one of the following: a fluoroelastomer (700), a fluorine containing ionic liquid (600), and a solution of a fluorine containing compound. The field probe further includes an antenna (406) for manipulating the magnetic spins of the fluorine sample and for receiving fluorine magnetic resonance data from the fluorine sample. The antenna is connected to the radio-frequency transceiver. The method includes acquiring (100, 200) the fluorine magnetic resonance data using the magnetic resonance imaging system and calculating (102, 206) a magnetic field strength (344) using the fluorine magnetic resonance data.
