Iterative SENSE reconstruction


In this clip, we demonstrate how iterative image reconstruction methods can be used to reconstruct images from undersampled MRI data from multiple receive coils. Ordinarily, such undersampling leads to gross image distortions (see the images at the first iteration), but our iterative reconstruction method, used in conjunction with information about receiver coil sensitivity, converges to high quality images. These methods can allow images to be acquired more quickly for functional brain imaging studies using MRI.

Details.
The k-space trajectory has 2363 data points, with 4us sampling, roughly corresponding to a 32 x 32 image in a 11cm FOV. The reconstructed images are 64 by 64, FOV 22 cm.
