Phase correction and reconstruction in phase‐corrected DP 3D TSE. The phase error map Δϕ j,n (x, y) for each individual diffusion acquisition j and shot n is estimated from the low‐resolution navigator data in image space, where the T₂‐weighted (b = 0) data are used as a reference. Phase correction per shot and per diffusion acquisition of the imaging data with the estimated phase error is done voxel‐wise in the hybrid space (x, y, k_z). Corrected imaging data are then reconstructed along k _z to obtain the final image. LPF, low‐pass filter; FFT, fast Fourier transform.
