Latest Patents

One of Changyu Sun's latest patents is titled "Systems and methods for phase unwrapping for dense MRI using deep learning." This invention focuses on a method of cardiac strain analysis that utilizes displacement encoded MRI data. It involves generating phase images for each frame of the MRI data, which may include phase-wrapped measured values. A convolutional neural network (CNN) is employed to compute a wrapping label map, which indicates the number of phase wrap cycles at each pixel. The unwrapped phase image is then used for myocardial strain analysis.

Another notable patent is "Multiband spiral cardiac MRI with non-cartesian reconstruction methods." This computerized method reconstructs acquired MRI data to produce a series of output images. It involves acquiring multiband k-space data from multiple slices of spiral MRI data and simultaneously obtaining a single band k-space data set. The method includes calculating calibration kernels for each multiband slice and applying phase demodulation techniques to separate the slices effectively.
