Lower Error Bounds for the Estimation of Relaxation Parameters
It is not improbable that biological tissue shows an intrinsic heterogeneity in respect of these parameters.
Comparing data from different laboratories, one can observe large variations caused by different measuring methods, field dependencies, and other systematic errors. These will hopefully be eliminated by an appropriate standardization procedure, as proposed in an EEC project (Podo 1988).
Statistical errors are caused by parameter estimation over noisy data, sometimes combined with errors caused by the illconditioned problem of resolving multiple relaxation times.
