Abstract: Systems and methods of image reconstruction are provided. A system may have a memory and a processor to receive data corresponding to magnetic resonance imaging coils and data corresponding to a region of interest within a field of view of the magnetic resonance imaging machine. By determining different weights to associate with virtualized magnetic resonance imaging coils, images may be reconstructed to favor signals associated with a region of interest and to disfavor interference associated with areas outside the region of interest.

Abstract: Methods, systems, devices and apparatuses for generating a high-quality MRI image from under-sampled or corrupted data The image reconstruction system includes a memory. The memory is configured to store multiple samples of biological, physiological, neurological or anatomical data that has missing or corrupted k-space data and a deep learning model or neural network. The image reconstruction system includes a processor coupled to the memory. The processor is configured to obtain the multiple samples. The processor is configured to determine the missing or corrupted k-space data using the multiple samples and the deep learning model or neural network. The processor is configured to reconstruct an MRI image using the determined missing or corrupted k-space data and the multiple samples.

Abstract: A method for identifying and spatially mapping microenvironments using coarse-resolution correlation spectroscopic imaging includes acquiring, using a magnetic resonance imaging (MRI) scanner, acquired data that includes high-dimensional contrast encoded data of a target for each of multiple voxels. The method also includes creating, using a signal processor, a model of the acquired data as a spatially-varying mixture of high dimensional real-valued exponential decays. The method also includes estimating, using the signal processor, a multidimensional correlation spectroscopic image that includes a multidimensional correlation spectrum at each of the multiple voxels.
