Systems and methods for automatic voxel positioning in magnetic resonance spectroscopy

摘要

Systems and methods for automated voxel positioning in magnetic resonance spectroscopy (“MRS”) are provided. In some aspects, a method includes receiving magnetic resonance (“MR”) imaging data acquired from a subject using an MR imaging system and registering the MR imaging data to an atlas having a pre-defined volume of interest (“VOI”), or segmenting a region of interest (“ROI”) directly from the MR data. The method also includes generating registration parameters based on the registration, and computing a transformed VOI using the pre-defined VOI in the atlas and the registration parameters. Alternatively, the VOI may be obtained by directly estimating it from the ROI.
