==METAMATERIAL SLAB FOR MRI - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240036133 titled 'METAMATERIAL SLAB FOR MRI

==Simplified Explanation==

The abstract describes a metamaterial (MTM) slab that can passively interact with a magnetic resonance imaging (MRI) system to improve the homogeneity, specific absorption rate, and/or strength of the magnetic field generated by a transmit device. The MTM slab can also act as a receiver for the MRI by being connected to RF receive circuitry.

* The MTM slab consists of a first layer and a second layer, with the second layer offset from the surface defined by the first layer.
* The first layer and the second layer form a 2D transmission line that supports radio frequency (RF) current along the surface in two directions: a first direction and a second direction transverse to the first direction.
* The first layer and the second layer are connected via linking capacitors.

Potential applications of this technology:
* Improved homogeneity of the magnetic field in MRI systems, leading to better image quality and accuracy.
* Enhanced specific absorption rate (SAR) control, allowing for safer and more efficient MRI scans.
* Increased strength of the magnetic field, enabling faster imaging and improved signal-to-noise ratio.

Problems solved by this technology:
* Inhomogeneity of the magnetic field in MRI systems, which can cause image artifacts and inaccuracies.
* High SAR levels, which can lead to tissue heating and potential patient discomfort or harm.
* Limited strength of the magnetic field, resulting in longer scan times and reduced image quality.

Benefits of this technology:
* Improved image quality and accuracy in MRI scans.
* Safer and more efficient MRI procedures with better SAR control.
* Faster imaging and higher signal-to-noise ratio for enhanced diagnostic capabilities.


==Original Abstract Submitted==

a metamaterial (mtm) slab for a magnetic resonance imaging (mri) system passively interacts with a field generated by a transmit device to improve homogeneity of the field, specific absorption rate, and/or strength of the field. the mtm slab may also be connected to rf receive circuitry at one or more ports to act as a receiver for the mri. the mtm slab may comprise a first layer generally defining a surface and a second layer offset from the surface generally defined by the first layer, the first layer and the second layer interacting to form a 2d transmission line supporting radio frequency (rf) current along the surface in a first direction and in a second direction transverse to the first direction, the first layer and the second layer being connected via linking capacitors.
