Abstract
En 中文
Spherical and linear b-tensor encoding (STE and LTE) enables quantification of microscopic diffusion anisotropy and diffusional variance. However, such waveforms are often variably sensitive to time-dependent diffusion, causing rotational variance and spectral mismatch. We propose double-isotropic matched encoding (DIME), which enforces isotropy in diffusion- and restriction-weighting tensors (
and
) and STE/LTE pairs matched in restriction sensitivity.
