Phased array coil and parallel imaging technology of MRI / 医疗卫生装备

ABSTRACT

The parallel imaging technology of MRI is the latest technique emerging in the last few years, which is based on the phased array coil. SMASH procedure operates by simultaneously acquiring linear combination signals with different spatial sensitivities from the phased array coils to reduce the phase encoding and shorten the imaging time. SENSE procedure operates by increasing the pace when sampling is performed in k-space, which proves a speedup by reducing the number of encoding steps. When the phased array coil designed, such problems have to be taken into account as resonant frequency, impedance match, mutual impedance and et al.
