Rapid and effective correction of RF inhomogeneity for high field magnetic resonance imaging.

The well-known variability in the distribution of high frequency electromagnetic fields in the human body causes problems in the analysis of structural information in high field magnetic resonance images. We describe a method of compensating for the purely intensity-based effects. In our simple and rapid correction algorithm, we first use statistical means to determine the background image nois...

RF Inhomogeneity Correction Algorithm in Magnetic Resonance Imaging

MR images usually present grey level inhomogeneities which are a problem of significant importance. Eliminating these inhomogeneities is not an easy problem and has been studied and discussed in several previous publications. Most of those approaches are based on segmentation processes. The algorithm presented in this paper has the advantage that it does not involve any segmentation step. Inste...

RF Field Analysis for High Field Magnetic Resonance Imaging Systems

The combined field integral equation method is used to calculate the RF B1 field produced by a transmission line resonator element for high field magnetic resonance systems. The proposed method provides faster electromagnetic field results than the finite difference time domain approach. A field localization method is also discussed.

Regularized Estimation of Main and RF Field Inhomogeneity and Longitudinal Relaxation Rate in Magnetic Resonance Imaging

Regularized Estimation of Main and RF Field Inhomogeneity and Longitudinal Relaxation Rate in Magnetic Resonance Imaging by Amanda K. Funai Chair: Jeffrey A. Fessler In designing pulses and algorithms for magnetic resonance imaging, several simplifications to the Bloch equation are used. However, as magnetic resonance (MR) imaging requires higher temporal resolution and faster pulses are used, ...
