Market Opportunity

Magnetic resonance imaging (MRI) requires placing the region of interest (ROI) in a static magnetic field, exciting nuclear spins in the object with a RF magnetic field, and then detecting the signals emitted. For in-vivo high-field MRI (≥3T), it is important to consider the homogeneity of the active RF field. During the excitement phase, a non-uniform field is created. This non-uniformity of excitation fields causes image contrast to vary within an image, making interpretation and quantification difficult. In high-field abdominal, cardiac, and neuro imaging, inhomogeneity of excitation fields on the order of 50% has been observed. Current methods to address non-uniformity are limited by long imaging times and motion compensation issues.

USC Solution

USC researchers have developed a rapid imaging technique capable of excitation mapping in moving body parts such as the chest and abdomen. This method is substantially faster and corrects the inhomogeneity of excitation fields.
