Gradient Amplifier Series: Robust, Low-Noise Gradient Amplifiers for Imaging
AE Techron is an industry pioneer in MRI. Our engineers developed some of the first commercially available gradient amplifiers ever made. We bring this experience to the design of every new gradient amplifier in our product line. The AE Techron 7000 Series gradient amplifiers are high-power, DC-enabled linear amplifiers with an integrated power supply. They offer a wide bandwidth and exceptional control of drift and distortion.
One key differentiation of AE Techron gradient amplifiers compared to typical gradient amplifiers from other suppliers is the very-low-noise linear topology. A key benefit of this approach is the elimination of switching noises, which makes it possible to achieve good image quality with magnetic fields below 100 mT. Because the 7000 Series has no ripple noise, no synching with the console is required.
The 7000 Series products can function as either a voltage or current source, making them valuable for environments with multiple applications. The 7224 model uses single-phase AC power, while the 7548, 7796, and 7794MRL models operate using three-phase power.
By further reducing the already low system non-linearities found in our other MRI systems, The 7794MRL is able to be used successfully in research systems with field strengths as low as an amazing 6 mT.
