Claims20
A magnetic resonance field-cycling instrument comprising one or more of an electronic fast switching insolated gated bipolar transistors or a storage capacitor in order to power field-cycling electronics, which allows a user to perform field cycling experiments in a magnet on a sample size that is greater than about 5 cm and less than about 25 cm in diameter.
A magnetic resonance field-cycling instrument comprising an electronic fast switching insolated gated bipolar transistor and a storage capacitor, wherein said magnetic resonance field-cycling instrument has a magnet that is about 20 cm in an inner diameter and an electronic switching time that is less than about 10 msec.
A magnetic resonance field-cycling instrument comprising an electronic fast switching insolated gated bipolar transistors and a storage capacitor in order to power field-cycling electronics, further comprising high voltage diodes, one or more current amplifiers, one or more resistors, one or more shunts;
- and one or more fuses which allows a user to perform field cycling experiments in a magnet on a sample size that is greater than about 5 cm and less than about 25 cm in diameter.
