I am a biomedical engineer working in magnetic resonance imaging (MRI) with RF/microwave and mechatronics background. I am specifically interested in studying three primary topics: (1) hardware development for MR engineering applications, (2) multi-physics theoretical and computational modeling of MRI and other biomedical processes, and (3) hardware-/ and RF development for cellular and molecular imaging modalities.

  • Practical Methods for Improving B-1(+) Homogeneity in 3 Tesla Breast Imaging JOURNAL OF MAGNETIC RESONANCE IMAGING Winkler, S. A., Rutt, B. K. 2015; 41 (4): 992-999

    Abstract

    To improve image contrast and B1+ field homogeneity in 3 Tesla (T) breast MR.Two practical B1+ shimming methods for 3T breast MR are presented; low-cost passive shimming using local pads of high dielectric permittivity (εr from 0 to 100), and two-channel radiofrequency (RF) shimming (adjusting Q-I amplitude ratios and phase differences of 0 to -4 dB and 90 to 45 degrees), as well as a combination of both methods. The technique has been studied both in simulation using a numerical body model with added mammary tissue and in vivo in six subjects.Large improvements are observed with both methods, leading to a decrease in left-right B1+ asymmetry ratio of 1.24 to 1.00 (simulation) and from 1.26 to 1.01 (in vivo). RF safety was not adversely affected.Both RF shimming and dielectric shimming were shown to improve inhomogeneity in the B1+ field in 3T breast MR. J. Magn. Reson.
