titleOfInvention | Automatic frequency tuning of MR device |
abstract | PROBLEM TO BE SOLVED: To provide a method for automatically tuning a radio frequency transmitter and a receiver of a magnetic resonance imaging apparatus to an optimum frequency. SOLUTION: A magnetic resonance signal is converted into a frequency domain, The spectral intensity of the signal is calculated (106). A centroid interpolation is performed on the spectral intensities (110) to obtain the desired frequency sampling. A model function is created based on the strength of the main magnetic field with peaks separated by the same boundaries as the fat and water signal boundaries. The spectral intensity is correlated 112 with the model function to find the peak with the highest intensity therefrom. Empirically obtained information on the positions of chemical species peaks along the spectrum intensity, Predicted from main magnetic field strength and correlation peak position (11 4). The region of spectral intensity to be examined is identified from the empirically obtained information (116) and the peak in this region closest to the predicted location is found (11). 8). |
