Abstract
A method that is usable with an NMR measurement apparatus includes averaging first spin echo trains acquired from different regions of a sample to form a second spin echo train. The first spin echo trains are used to produce a first estimate of a property of the sample, and the first estimate has a first resolution and a first accuracy. The second spin echo train is used to produce a second estimate of the property, and the second estimate has a second resolution that is lower than the first resolution and a second accuracy that is higher than the first accuracy. The first and second estimates are combined to produce a third estimate of the property. The third estimate has a third resolution near the first resolution of the first estimate and a third accuracy near the second accuracy of the second estimate.
