Discription |
| n | frequency |
| g | gyromagnetic ratio |
| B0 | standing magnetic field |
| x | spatial coordinate |
| y | spatial coordinate |
| n0 | Larmor Frequency, frequency of induced nuclear magnitic spin |
| Gx | frequency encoding gradient, magnetic field gradient in x dimension |
| G0 | phase-encoding gradient, magnetic field gradient at 0° of projection |
| d | spectral frequency response coordinate: chemical shift |
| q | projection angle |
| BW(q) | sampling frequency bandwidth used by MRI to record a specified projection angle, q |
| BWq=0 | sampling bandwidth at 0° |
| BWq=90 | sampling bandwidth at 90° |
| q | spectral width of the field of view of the purely spectral projection q |
| D | spatial width of the field of view of the purely spatial projectionq |
| T1 | spin lattice relaxation time |
| FWHM | full width at half maximum |
| qs | number of samples (projections) from the sinogram |
