| idamnjanovic@64 | 1 CardiacMRI: |
| idamnjanovic@64 | 2 - Last thing I was dealing with was temporal fft operator that I have put in opFFTxd.m in util directory. |
| idamnjanovic@64 | 3 - Problem setup is now kind of realistic: |
| idamnjanovic@64 | 4 - user choose upload cardiac images from dataset |
| idamnjanovic@64 | 5 - he can shose the slice number (1-10 - default is 5) |
| idamnjanovic@64 | 6 - sigma level (0.05 by default) |
| idamnjanovic@64 | 7 - undersampling factor (fold default is 6) |
| idamnjanovic@64 | 8 - n image size (256 by default) |
| idamnjanovic@64 | 9 - read 3d matrix of n*n cardiac images in szt time points |
| idamnjanovic@64 | 10 - adds noise sigma*var(signal) |
| idamnjanovic@64 | 11 - do 2d circular fft per image and take random lines as specified by mask |
| idamnjanovic@64 | 12 - mask is made to sample n*szt/fold lines in phase encode and time dimensions |
| idamnjanovic@64 | 13 - play movies of original, undersampled cardiac images and mask |
