Title: Innovations of Junmin Liu in Magnetic Resonance Imaging
Introduction
Junmin Liu is a notable inventor based in London, Canada. He has made significant contributions to the field of magnetic resonance imaging (MRI) through his innovative patents. With a total of 2 patents, Liu's work focuses on enhancing imaging techniques and improving diagnostic capabilities.
Latest Patents
Liu's latest patents include a method for Dixon MRI, multi-contrast imaging, and multi-parametric mapping with a single multi-echo gradient-recalled echo acquisition. This invention presents a multi-echo gradient echo protocol that generates multi-contrast images and extracts multi-parametric maps. An example implementation at 3 T acquires a short-TE train, which is used to map B0 inhomogeneity and proton density fat fraction (FF). Additionally, a second long-TE train enables quantification of local frequency shift (LFS) and susceptibility. The pipeline automatically generates co-registered images and maps, including magnitude- and complex-based FF maps, B0 maps, anatomical images, and susceptibility-sensitive images for each echo. This invention is applicable to whole head/neck, liver, knee, or even whole body scans.
Another significant patent by Liu involves systems and methods for field mapping in magnetic resonance imaging. This patent presents unwrapping based B0 mapping systems and methods. An initial B0 map is obtained by unwrapping a pseudo-in-phase complex data generated from selected echoes of multi-echo gradient echo image data. The method corrects global and local phase errors to produce a phase-error-corrected B0 map, which is then used to generate a final B0 map.
