Title: Innovations of Hongmei Zhu in Medical Imaging
Introduction
Hongmei Zhu is a prominent inventor based in Calgary, Canada, known for her significant contributions to the field of medical imaging. With a total of seven patents to her name, she has developed innovative methods that enhance the quality and accuracy of MRI data analysis.
Latest Patents
One of her latest patents is titled "Filtering artifact from fMRI data using the Stockwell transform." This invention presents a method for filtering time-varying MR signal data prior to image reconstruction. The process involves applying a one-dimensional Fourier Transform (FT) to the MR signal data along each frequency-encode line of k space. By calculating the phase of each complex pair of the FT transformed data, a phase profile is created for each frequency-encode line. This method effectively identifies and removes high-frequency artifacts while preserving the frequency content of the remaining signal, enabling the detection of subtle frequency changes over time.
Another notable patent is "Visualization of S transform data using principal-component analysis." This invention relates to a method for visualizing ST data based on principal component analysis. It allows for the reduction of dimensionality of local S spectra corresponding to image points of an object. The method generates a texture map for display, which is beneficial for motion artifact suppression in MRI image data, texture analysis, and disease-specific tissue segmentation.
