DYNAMIC B0 FIELD DETECTION BY MAGNETIC RESONANCE NAVIGATORS IMPROVING B0 MAPPING AND CORRECTION ABOUT MULTICHANNEL RECEPTION AND/OR TRANSMISSION RADIO FREQUENCY COIL CONFIGURATIONS

摘要

PURPOSE: Dynamic B0 field detection by magnetic resonance navigators, multichannel reception and/or transmission radio frequency coil configurations are provided to improve B0 matching for image correction using navigators received from each of channels.;CONSTITUTION: A magnetic resonance data acquisition apparatus includes a radio frequency (RF) reception coil array. Each channel of multichannel RF coil array includes a RF coil. A navigator pulse is activated in the magnetic resonance data acquisition apparatus in which a B0 field exists. In the each channel of the multichannel RF array detects and generates a navigator response signal. Localization information providing the navigator response signal to a computerized processor and identifying each location of the multichannel RF array coils is provided. The computerized processor systemizes the navigator response signal through the localization information and forms the B0 field map into a data file usable in an electronic method.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) MR coil array
