Filed:
Jun 2, 2011
Appl. No.:
13/151556

Assignee:
Vanderbilt University - Nashville TN
International Classification:
A61B 5/055
US Classification:
600410
Abstract:
Systems and methods for characterizing bone structures are provided for characterizing bone structures. In the system and method, one or more H NMR or MRI signals associated with a bone structure are obtained. Thereafter one or more signal parameters are computed from the obtained signals, where each of the signal parameters comprising at least one of a relaxation rate constant or a corresponding signal amplitude associated with a component of the obtained signals defined by a Tvalue or a range of Tvalues. Finally, the mechanical properties or fracture risk for the bone structure are determined based on the computed signal parameters and stored correlation data.
Mri Using Rf Gradients For Spatial Encoding

20150253403, Sep 10, 2015
Filed:

Appl. No.:
14/642843
Inventors:

International Classification:
G01R 33/48
Abstract:
Embodiments of the invention concern systems and methods for performing MRI using RF gradients for spatial encoding. One aspect of the invention involves providing |B|-selective pulses designed using the Shinnar-Le Roux algorithm. Another aspect of the invention involves RF encoding based on the Bloch-Siegert (BS) shift. Together, these techniques can be used to support MRI based on RF gradient encoding instead of the conventional Bencoding.
