Market Opportunity

Clinical magnetic resonance imaging (MRI) is experiencing a strong trend towards high-field imaging due to its ability to scale its signal-to-noise ratio (SNR) linearly with field strength. Increasing SNR is important in imaging because it results in a significant increase in sensitivity. This increase in sensitivity is needed to compensate for the non-uniformity found in magnetic fields of 3T or higher. This non-uniformity of excitation fields causes image contrast to vary within an image, making interpretation and quantification difficult. Accordingly, there is a need for methods and systems that compensate for non-uniformity and thereby reduce variations in intensity and contrast across MRI images.

USC Solution

USC researchers have developed a processing system designed to cancel out variation within an excitation field. Through this method, regions of interest become easier to interpret and diagnose.
