Latest Patents

One of her latest patents focuses on "Metal resistant MR imaging." This invention relates to a method of MR imaging near metal parts using a technique called SEMAC. The objective is to provide an improved MR imaging technique that is both fast and robust against susceptibility effects. The invention proposes applying a weaker slice-selection magnetic field gradient to reduce ripple artifacts near metal parts. Additionally, it suggests using undersampling in the slice-selection direction of the SEMAC sequence or combining both methods. A sparsity constraint is also utilized to stabilize the reconstruction of the undersampled MR images. Furthermore, the invention encompasses a MR device and a computer program designed for use on such a device.

Another significant patent addresses the "Restriction of the imaging region for MRI in an inhomogeneous magnetic field." This invention aims to suppress the back-folding of distant off-resonant signals into the region of interest when imaging near metallic objects, such as metal implants. The imaging volume is spatially restricted by selection gradients applied concurrently with excitation and refocusing RF pulses in a spin echo sequence. The selection gradient during the excitation pulse has a different amplitude or polarity compared to that during the refocusing pulse, allowing for a more effective imaging technique.
