The invention relates to method for generating an MRI image in which a radial or spiral k-chamber path with a constant angular increment Psi is used to take an MRI image, said angular increment Psi being in the angular range of between 5 - 55 degrees or being in the corresponding supplementary angle Psi' and is selected according to the formula PsiN,M = pi / (N+1/ (M + tau - 1)). Alternatively, for an angular increment Psi which deviates from the angle increment of the optimal distribution of n radial profiles Psiopt = 180°/n, the minimum scanning efficiency of the angular increment Psi for n > 21 profiles is greater than 0.95, the angular increment Psi is in an angular range of 5 to less than 68,7537°, in particular between 5 - 55 degrees or in the corresponding supplementary angle Psi'. |
