Composite MRI antenna with reduced stray capacitance |
摘要 |
An antenna system for a magnetic resonance imaging apparatus has an active coil connected between a transmitter or receiver and ground and also has an isolated loop coil which is not conductively connected to ground. The isolated loop coil preferably overlies the electrically conductive pole surface of the field magnet. The isolated loop coil is inductively coupled to the active coil. The assembly has relatively low parasitic capacitance to ground and hence can be tuned to the resonant frequencies required for high field strength imaging.
