ASSESSMENT OF STRUCTURES SUCH AS BONE USING SPATIAL-FREQUENCY ANALYSIS

摘要

The disclosed innovation is a method for acquiring spatial frequency spectra from specific locations in a 3D sample usinc modifications of the current MRI techniques for localized NMI spectroscopy. The innovation in its simplest abstraction is tc add the use of a read out gradient to the current NMI spectroscopy pulse sequences and record the resultant echo. These techniques generate spectra from a selected region 02 generate an image of the results over a region of the sample. These methods can be applied to analyzing the structure oi trabecular bone as well as for analyzing or diagnosing disease in cases where there is a difference in the spatial frequency power spectrum due to physiologic or disease processes. Various embodiments are disclosed.
