Optimization of spin-lock times for T(1ρ) mapping of human knee cartilage with bi- and stretched-exponential models
Two optimization criteria based on Cramér-Rao Bounds are compared between each other and with non-optimized schedules for T(1ρ) mapping using synthetic data, model phantoms, and in-vivo knee cartilage. The curve fitting is done on complex-valued data using an iterative Nonlinear Least Squares (NLS)...
