Abstract

Parallel Imaging is one of the recent revolutions in Magnetic Resonance Imaging. As conventional gradient encoding is reaching its limits by dB/dt limits, spatial encoding via localized receiver coil sensitivities has brought a dramatic performance boost into the arena of MRI. Essentially, the use of parallel imaging affords less phase encoding steps and hence speeds up data acquisition. Aside from faster imaging, parallel imaging also caused giant leaps in RF receiver array technology development and thus to massive improvements in image quality and improved SNR at similar B0 levels. For many MRI pulse sequences parallel imaging helps to cut down scan time by factors ranging from 2 to 4, wh..
