Abstract:
A magnetic resonance imaging system for improved imaging quality, comprising:a magnetic resonance imaging apparatus (10) including: a first section (11, 12); a second section (11, 12); a vertical column section configured to interconnect the first section and the second section (13); wherein operation of the imaging apparatus (10) creates a magnetic resonance field having a magnetic resonance frequency; and wherein the sections (11, 12, 13) of the imaging apparatus are configured in a C-shape, whereby the imaging apparatus comprises a folded dipole having a self-resonant frequency; an RF cage (1 to 6) configured and oriented to enclose the imaging apparatus (10); and wherein the first section (11, 12) is electrically connected to the RF cage (1 to 6) via a capacitive impedance (111, 111â€²) sufficiently to electrically extend the folded dipole in order to reduce the folded dipole's self-resonant frequency below the magnetic resonance frequency.
