| 20080211499 | Low Power Decoupling for Multi-Nuclear Spectroscopy - In a magnetic resonance spectroscopy method, first nuclear species magnetic resonance is excited. A spin echo of the first nuclear species magnetic resonance is generated, and the spin echo is read out. The first and second nuclear species are decoupled during the generating of the spin echo but not during the reading. At least the generating, the reading, and the decoupling are repeated for a plurality of different decoupling times to generate heteronuclear J-modulated data. | 09-04-2008 |
| 20090079428 | MAGNETIC RESONANCE RF TRANSMISSION SYSTEM AND MR SYSTEM AND METHOD USING SAME - A radio-frequency transmission system for a magnetic resonance system has a radio-frequency amplifier and a signal splitter with two inputs and two outputs. The signal splitter is fashioned so that the power of a radio-frequency signal provided at one of the two inputs is divided between the two outputs. A first input the two inputs of the signal splitter is thereby coupled with the output of the radio-frequency amplifier, and the two outputs of the signal splitter respectively serve for connection to different inputs of a transmission antenna of the magnetic resonance system in order to feed the output signals present at the two outputs of the signal splitter into the transmission antenna. The second input of the signal splitter is terminated with a terminating resistor arrangement with a variable reflection factor. | 03-26-2009 |
