Article Title: Decoupling of a tight-fit transceiver phased array for human brain imaging at 9.4T: Loop overlapping rediscovered.
Article Snippet: Purpose: To improve the decoupling of a transceiver human head phased array at ultra-high fields (UHF, 7T) and to optimize its transmit (Tx) and receive (Rx) performance, a singlerow eight-element (1 8) tight-fit transceiver overlapped loop array was developed and constructed.. Overlapping the loops increases the RF field penetration depth but can compromise decoupling by generating substantial mutual resistance.. Methods: Based on analytical modeling, we optimized the loop geometry and relative positioning to simultaneously minimize the resistive and inductive coupling and constructed a 9.4T eight-loop transceiver head phased array decoupled entirely by overlapping loops.

Article Snippet: It then went through the gain-equalization circuit (blue square), which consisted of a low noise preamplifier (LNA) (Wantcom WMA1R1, Chanhassen, MN) followed by an attenuator (Minicircuits Gat-10+ to Gat-15+, Brooklyn, NY).

Article Title: Monitoring local heating around an interventional MRI antenna with RF radiometry
Article Snippet: The Dicke switch is connected to a low-noise preamplifier (LNA) (Wantcom, Inc., Chanhassen, MN, Gain = 28 dB; NF = 0.4 dB) and the signal from the LNA conveyed outside the room via a long coaxial cable incorporating several solenoidal and bazooka baluns that maintain signal integrity and minimize interference. fig ft0 fig mode=article f1 fig/graphic|fig/alternatives/graphic mode="anchored" m1 Open in a separate window FIG. 4. caption a7 Radiometry front-end switches (top) enable transition between three possible states (radiometry, gain calibration, local heating; below) during the experiments.
