Do anyone have a code to reconstruct images from the K space?

| GE 8 channel Body Coil Artifact |
Have a GE 1.5T HDxt. Problem: experiencing symmetric artifacts in abdominal images. Artifact seen in most anterior images: Some are rectangular in appearance, another reminds me of a plastic knife. All patients are changed in gowns/pants prior to entry into MRI suite. The body coil in question has been changed 3 times but the artifact remains. I suspect this is a hardware reconstruction issue, however, the engineer thinks it is operator error. I have run this sequence with and without options. This is an SSFSE, breath hold sequence. Has anyone encountered this issue?

| Matlab code for k-t GRAPPA |
Hello folks,
I am working on dynamic MRI, and I need to carry out some comparisons with the k-t GRAPPA reconstruction scheme. I was wondering if anyone has the Matlab code to share.
Best,
Morteza

is it possible to get mri hardware without computation hardware and software for image reconstruction?
I means, I want to by only hardware to get data from sensor and i have computation unit and software for image reconstruction...

| Building 3d Volumes from MRI DICOM |
In almost all cases, MRI images have a slice thickness far greater than their in-plane resolution, making multiplanar reconstruction meaningless. Also, most MRI images have a gap between the slices, which also renders multiplanar meaningless and impossible (unless you're happy with black bars where the slice gaps exist).
You can look at your images and the slice thickness is on the graphics. the slice gap is usually not displayed, but if you look at the slice location displayed on adjacent slices, and compare to the slice thickness, you can easily compute the slice gap.
The in-place resolution is (approx) the field of view divided by the acquisition matrix, both of which are also printed on the image somewhere.
By the way, if you have the dicom (.dcm) files, there is lots of data that's 'hidden' that you can access with a full featured dicom file editor.
