Latest Patents
Arjun's latest patents include a "Parallel magnetic resonance imaging method using a radial acquisition trajectory." This innovative method offers a fast and efficient way to reconstruct images from undersampled, parallel MRI data sets acquired with non-Cartesian trajectories. The process involves calculating unsampled k-space data from the acquired data and utilizing sets of calculated reconstruction coefficients. To minimize computation time, only a few reference reconstruction coefficients are calculated through a matrix inversion step, while the remaining coefficients are produced by interpolating between these references.
Another notable patent is the "Background suppression method for time-resolved magnetic resonance angiography." This method employs a 3D projection reconstruction pulse sequence during a CEMRA dynamic study to acquire a time course series of k-space data sets. It effectively suppresses signals from non-vascular voxels by reconstructing a corresponding series of low-resolution images and measuring the signal behavior against a model of unwanted signals. The resulting filtered low-resolution images are transformed back to k-space and combined with the originally acquired peripheral k-space data to create complete, filtered k-space data sets for image reconstruction.
