MAGNETIC FIELD PROBE FOR MRI WITH A FLUOROELASTOMER OR A SOLUTION OF A FLUORINE CONTAINING COMPOUND

摘要

A method of measuring a magnetic field within a magnetic resonance imaging system (300) comprising a magnet (304) with an imaging zone (308) and a radio frequency transceiver (316). The magnetic resonance imaging system further comprises a magnetic field probe (322) located within the imaging zone. The magnetic field probe comprises a fluorine sample (404) comprising 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 comprises 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 comprises the steps of 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.
