His work has significantly contributed to the field, particularly in methods that enhance the quality and efficiency of MRI data acquisition.

Latest Patents

One of his latest patents involves innovative concepts for acquiring MRI data specifically for angiography. This invention introduces novel magnetization preparation schemes that execute navigator and fat saturation pulses in a steady state after preparatory pulses. This approach minimizes the delay between magnetization preparation and image echoes. Additionally, it provides improved methods for contrast-enhanced MRI, where data is collected along non-linear trajectories through k-space, incorporating novel view ordering. The methods also include advanced motion corrections that reduce motion artifacts, as well as self-calibrated sensitivity-encoded parallel imaging techniques that facilitate accurate and rapid scanning of subjects.

Another significant patent by Nguyen is a method and apparatus for measuring and correcting motion effects using navigator echoes. This invention detects the displacement of an object through a linear regression on k-space data, fitting a straight line to the motion-induced phase shift. For more complex motions involving rotation and dilation, the invention determines rotation angles and scaling factors from magnitude k-space data. The resulting displacement vector is obtained from the phase data in k-space, utilizing a weighted least squares minimization approach.
