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.

Value Proposition

  • Faster imaging than market leader
  • Allows imaging of moving body parts
  • Increases diagnostic accuracy

Applications

  • Medical imaging
  • MRI scanners

Stage of Development

  • Experimentally validated
  • Available for exclusive and non-exclusive license
