Abstract
The present invention comprises a system and method for analyzing trabecular bone structure. A means for scanning the trabecular bone using a magnetic resonance image (MRI) scanner generates bone image data, which is then processed including correcting, deshading and reducing noise in the image data.
Claims17
A computerized system for analyzing trabecular bone structure of a selected anatomical region, the system comprising:
- magnetic resonance imaging (MRI) coil for scanning or rescanning the trabecular bone in the immobilized selected region to generate MR bone image data,, wherein image data comprises data acquired by signals emitted from bone marrow regions of the scanned trabecular bone;
- computer processor(s) operably linked to the scanner, for processing the image data or for creating derived quantitative parameters, or combinations thereof, the processor(s) comprising a function for correcting the image data to compensate for movement of a selected region relative to the coil during the scanning;
- a function for deshading the image data to minimize the effects of radio frequency inhomogeneity;
- and a function for reducing noise in the image data;
- operating computer readable medium encoded with one of the following:
- computer program software;
- computer executable instructions or instructions executed by the computer processor;
- and
- reporting component for outputting the processed image data or derived quantitative parameters, or combinations thereof.
