Unlocking the dynamic inner workings of the brain continues to remain a grand challenge of the 21st century. To this end, functional neuroimaging modalities represent an outstanding approach to better understand the mechanisms of both normal and abnormal brain functions. The ability to image brain function with ever increasing spatial and temporal resolution has made a significant leap over the past...
We have developed a new magnetic resonance electrical impedance tomography (MREIT) algorithm, RSM-MREIT. This new algorithm uses response surface methodology (RSM) and Simplex method to reconstruct subject's conductivity distribution. RSM-MREIT algorithm uses only one component of the measured magnetic flux density to reconstruct the conductivity images, and, consequently, solves the rotation problem...
We propose a novel magnetic resonance electrical impedance tomography (MREIT) algorithm, RBF-MREIT algorithm and apply it to reconstruct the conductivity distribution of human head. Computer simulations are conducted on a three-sphere head model to test the feasibility of the proposed algorithm. The simulation results demonstrate that the RBF-MREIT algorithm can estimate the conductivity values within...
We have applied the magnetic resonance electrical impedance imaging (MREIT) technique to image the three-dimensional (3D) conductivity distribution of the human head. Computer simulations were carried out on a tradition four-sphere head model to test the feasibility of imaging conductivity distribution of the human head. The present results show that the 3D head conductivity distribution could be...
