Title: Tiejun Zhao: Innovator in Magnetic Resonance Imaging

Introduction

Tiejun Zhao is a prominent inventor based in Pittsburgh, PA (US), known for his significant contributions to the field of magnetic resonance imaging (MRI). With a total of 9 patents to his name, Zhao has developed innovative methods that enhance the quality and efficiency of diagnostic imaging.

Latest Patents

One of Zhao's latest patents is titled "Systems and methods for diagnostic oriented image quality assessment." This method involves real-time assessment of image information using a computer with one or more processors. It includes obtaining a magnetic resonance (MR) image of a region-of-interest via a scanner and providing data to a deep learning model that has been trained on various sets of training data. The method assesses the data using the deep learning model and an image quality database to derive an assessed image quality value, ultimately classifying the image quality within a predetermined time frame from the initial scan.

Another notable patent is "Multi-slice acceleration for magnetic resonance fingerprinting." This method focuses on obtaining k-space data for MR volumes and applying controlled radio frequency (RF) pulses to excite multiple slices within the MR volumes simultaneously. The process produces a plurality of fingerprints from these slices, compresses at least one set of fingerprints, and reduces the residual signal of multiple signal evolutions. Additionally, the method includes periodically switching the weighting between different slices to optimize the imaging process.
