ASSESSMENT OF STRUCTURES SUCH AS BONE USING SPATIAL-FREQUENCY ANALYSIS

摘要

NMR spectroscopy in the disclosed invention is the location determined for the current MRI techniques used to transform the 3D sample of a particular the method for obtaining the spatial frequency spectrum from the position . The abstraction that the simplest use of the invention is to add to the current reading gradient NMR spectroscopic pulse sequences and recording the echoes that occur as a result. This technique produces an image of the result produced in the region of the spectrum , or a sample from a selected region . This method is not only the case of analyzing the structure of the fibrous bone , or physiological differences in the spatial frequency power spectrum due to the process of the disease can also be applied to a case in which analysis or diagnosis of disease , if there . Various embodiments are disclosed .
