Latest Patents

Zahneisen's latest patents include a method for magnetic resonance imaging that utilizes an un-supervised convolutional neural network for distortion map estimation and correction. This method involves performing an echo planar imaging acquisition using inverted up/down phase encoding directions. It reconstructs acquired images that have geometric distortions along the phase encoding directions due to off-resonant spins. The convolutional neural network is trained to minimize a similarity metric between un-warped up/down image pairs, allowing for effective geometric distortion correction.

Another notable patent is the algebraic reconstruction method for off-resonance and eddy-current correction in functional and diffusion-weighted magnetic resonance imaging. This method improves the correction of MRI images by employing a hybrid representation of the image reconstruction problem. It utilizes Fourier transformation and joint least squares reconstruction, which incorporates known phase variations due to system non-ideality. This innovative approach enhances the quality of MRI images significantly.
