Latest Patents

One of his latest patents is titled "Fast sparse computed tomography image reconstruction from few views." This method involves acquiring a sparse measurement matrix using a CT scanner and applying a reconstruction process over several iterations to reconstruct image data. The process includes generating a random view subset and determining a portion of the sparse measurement matrix corresponding to that subset. Additionally, it employs stochastic gradient descent and proximal total variation regularization to enhance image quality.

Another significant patent is "Memory efficiency of parallel magnetic resonance imaging reconstruction." This computer-implemented method utilizes a parallel computing platform to reconstruct magnetic resonance images. It involves receiving multiple coil data sets from a magnetic resonance imaging system and applying an iterative compressed-sensing reconstruction process. Each iteration optimizes data fidelity values and computes an estimated image based on the collected data.
