Abstract
The transmission antenna apparatus is configured for emitting transmission magnetic fields in magnetic resonance imaging devices and includes one or more flat antennas. A magnetic resonance imaging device includes such a transmission antenna apparatus.
Claims17
A transmission antenna apparatus configured for emitting transmission magnetic fields in magnetic resonance imaging devices, the transmission antenna apparatus comprising:
- at least a first flat loop antenna, a second flat loop antenna, and a third flat loop antenna, the first flat loop antenna being spaced apart from and non-overlapping with the third flat loop antenna, at least a first conductor piece of the first flat loop antenna and a second conductor piece of the third flat loop antenna extending at least in part within the second flat loop antenna in planar directions of extent of the second flat loop antenna;
- and
- feed apparatuses configured for feeding the first conductor piece of the first flat loop antenna in an opposite direction to the second conductor piece of the third flat loop antenna.
