In this paper, we propose a novel approach called robust iterative self-consistent parallel imaging reconstruction (RSPIRiT) in parallel magnetic resonance imaging (pMRI). Different from the smooth Tikhonov regularization used in SPIRiT, our model utilizes generalized Lasso to fix calibration errors in the reconstruction process. It results in a non-smooth optimization problem, which we introduce...
A super resolution reconstruction method for synthetic aperture radar (SAR) target is proposed under the condition of sparsity. The target is reconstructed by several high resolution sinc functions. By converting the super resolution problem to the least square estimation problem, relax algorithm is applied. In order to reduce the sidelobe, a hanning window is added in the frequency domain after the...
An magnetic induction tomography (MIT) hardware system is introduced in this paper. The system is composed of nine parts: signal source, sensor coils, preamplifier, canceling circuit, difference circuit, lock-in amplifier and the controller. One-dimensional measurement has been made, the relation between the phase variety and the conductivity of sample was constructed. A rectangular water-tank was...
