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