27.4 A sub-1dB NF dual-channel on-coil CMOS receiver for Magnetic Resonance Imaging

Magnetic Resonance Imaging (MRI) is a widely used medical imaging technique. It employs a strong static magnetic field (1.5 to 10.5T for human imaging) to split the spin states of the 1H nuclei in the body, and RF excitation to induce transitions and coherence among them. Gradient fields are superimposed to modulate the 1H resonance frequency, which enables… CONTINUE READING
