Title: B1 mapping in mri system using k-space spatial frequency domain filtering
Inventor: DANNELS WAYNE R
IPC: A61B5/055
Filed: 2010-03-18
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for determining or computing an improved B1 map for determining a spatial pattern and amplitude of a transmission high frequency magnetic field in an MRI (magnetic resonance imaging) apparatus.  <P>SOLUTION: At least one set of B1 amplitude tagged MRI data signals in spatial frequency domain k-space is collected from MR nuclei within an imaged volume of the MRI system, and such k-space data are processed to produce at least two sub-sets of frequency-filtered k-space data which are separately converted into corresponding spatial domain data sets. A baseline absolute value set and a harmonic absolute value set are arithmetically combined for every pixel, and upper and lower absolute value envelope data set values are processed for every pixel to generate a B1 map value based on a reverse function of a value related to the ratio of the upper and lower pixel data values in the predetermined pixel positions in the spatial domain. Based on the data, the B1 map value is stored or displayed, and the obtained diagnostic MR images are corrected/revised for every patient.  <P>COPYRIGHT: (C)2011,JPO&INPIT
