Abstract:
MRI requires high-Q resonators as RF-antennas generating a homogeneous B1-field. The antenna’s Q-factors depend on internal losses due to the matching network and the phantom’s impact. To improve performance during in-vivo measurements, resonant frequency and matching should be nearly independent from the loading.
