Parallel MRI Reconstruction Using B-Spline Approximation
Original language description
Parallel MRI (pMRI) is a way to increase the speed of the MRI acquisition by sampling more sparsely in the k-space. The decrease of the data amount causing aliasing is compensated by a simultaneous use of several coils with distinct spatial sensitivities. We propose a new algorithm that estimates the coefficients of the linear reconstruction transformation directly without estimating the coil sensitivity maps first. The coefficients are approximated by B-spline functions. This reduces the number of variables and thus speeds up the estimation. It also makes the method more robust to noise. Tests were performed on phantom images. The proposed method had lower square difference error than two commercially used methods GRAPPA and mSENSE.
