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.
Claims18
An image reconstruction system, comprising:
- a memory configured to store image data or k-space data;
- and
- a processor coupled to the memory and configured to:
- determine a region of interest of the image data or the k-space data,
- determine a region of non-interest of the image data or the k-space data;
- determine coil combination weights that optimize a signal-to-interference ratio of the image data or the k-space data based on the region of interest and the region of non-interest, and
- generate or reconstruct a magnetic resonance imaging (MRI) image or k-space data based on the image data or the k-space data and using the coil combination weights.

- determine a region of non-interest of the image data or the k-space data;
- determine coil combination weights that optimize a signal-to-interference ratio (SIR) of the image data or the k-space data based on the region of interest and the region of non-interest;
- generate or reconstruct a magnetic resonance imaging (MRI) image based on the region of interest of the image data or the k-space data;
- and
- transmit the generated or reconstructed MRI image for display.
A method of generating a magnetic resonance imaging (MRI) image, comprising:
- obtaining, by a processor, image data or k-space data;
- determining, by the processor, a region of interest of the image data or the k-space data;
- determining, by the processor, a region of non-interest of the image data or the k-space data;
- determining, by the processor, coil combination weights that optimize a signal-to-interference ratio of the image data or the k-space data based on the region of interest and the region of non-interest;
- and
- generating or reconstructing, by the processor, the MRI image based on the image data or the k-space data using the coil combination weights.
