Magnetic Resonance Imaging (MRI) is a powerful tomographic imaging technique based on sampling of Fourier data in a series of measurements. To reduce the number of measurements, parallel imaging utilizes data from multiple receive coils which each produces a signal modulated by a different spatial sensitivity profile. We will discuss robust algorithms for parallel imaging that avoid explicit calibration of the sensitivities by formulating reconstruction as a non-linear inverse problem.
