Abstract:
1. A method of assessing a spatial frequency distribution within a sample of a structure comprising: a) subjecting the sample to a magnetic field; b) subjecting the sample to magnetic resonance excitation; c) receiving an echo signal from the sample while the sample is subjected to a magnetic field gradient; d) taking an inverse transform of the received echo signal to obtain an echo signal intensity in one dimension; e) identifying a region of interest in the echo signal intensity in one dimension; f) windowing the region identified in e) to shape the echo signal intensity in the region of interest; g) taking a transform of the windowed echo signal intensity in one dimension obtained in f); and, h) analyzing the one dimensional spatial frequency content in the transform obtained in g) in order to access a one dimensional spatial frequency distribution within the sample of the structure without having to acquire all of the data required to create an image.
