Lower Parasitic Multi-Turn MRI Phased Array Coil
摘要:
Described herein is a lower parasitic multi-turn MRI phased array coil wherein the geometry is substantially identical between the coil turns. The potential of every corresponding point between the turns of the coil is also substantially equal, for example by using capacitors of substantially equal value and/or using substantially equal lengths of copper trace between breaks. As a result of this arrangement, the potential between coil turns is substantially equal, for example, with substantially equal capacitor value and substantially equal break point on conductor trace. This in turn reduces parasitics between turns because the geometry of each turn of the coil is substantially identical. The lower parasitic multi-turn MRI phased array coil is suitable for use with wired or wireless phased array coils, and is particularly well suited for use with lower field MRI systems.
