文摘
- •
Double PFG (d-PFG) MR experiments performed on tilted microcapillaries are described.
- •
Simulations of the signal in double-PFG MR experiments for tilted compartments are presented.
- •
The fittings of the d-PFG MR data provide accurate estimate of pore size and pore direction simultaneously.
- •
This microstructural information can be obtained partially even for phantoms having more than a single pore size.
