Amplifies Transceiver Antenna Elements
A magnetic resonance imaging (MRI) method and apparatus amplifies radio frequency (RF) signals from MRI coils. The coils, containing antenna elements, are power amplified by a distributed power amplifier with electronic devices (e.g., field-effect transistors). The approach locates an MRI coil with antenna elements within an MR magnet and amplifies its RF signal to obtain high-power RF pulses. These amplified pulses are then thermally and/or mechanically coupled to their respective antenna elements to form a hybrid coil-amplifier for MRI or spectroscopy machines.
High Magnetic and Electric Field Compatible
The amplification can be performed remotely, as can adjustments of the gains, electrical resistances, inductances and/or capacitances that control the magnitude, phase, frequency, spatial profile, and temporal profile of the RF signal. The components of this technology are compatible with/function in high magnetic fields (up to and exceeding one tesla or even ten tesla or more, and/or an electric field of many thousands of volts per meter).
