Title:
複数の送信コイルを有する磁気共鳴映像システム
Document Type and Number:
Japanese Patent JP2006508759
Kind Code:
A
Abstract:
The invention relates to an MRI system ( 1 ) for nuclear magnetic resonance imaging which comprises a plurality of transmit coils ( 11, 12 ). Each coil receives a coil drive signal (SD 1 , SD 2 ). The respective coil drive signals have the same shape, but may have a different amplitude and phase, controlled by a controller ( 103 ) on the basis of characteristic information in a memory ( 104 ) as well as user input information. The controller is designed to set the respective amplitudes and phases in such a way that the resultant overall B1 field is as homogeneous as possible in a volume of interest.
