Systems for a radio frequency coil for mr imaging

Abstract

Various methods and systems are provided for a flexible, lightweight and low- cost stretchable radio frequency (RF) coil of a magnetic resonance imaging (MRI) system. In one example, a RF coil assembly for a MRI system includes a loop portion comprising distributed capacitance conductor wires, a coupling electronics portion including a pre-amplifier; and a stretchable material to which the loop portion and coupling electronics portion are attached and / or enclosed therein.

Background technique [0004] Magnetic resonance imaging (MRI) is a medical imaging modality that creates images of the inside of the human body without the use of x-rays or other ionizing radiation. MRI systems include superconducting magnets to generate a strong, uniform static magnetic field. When a human body or part of a human body is placed in a magnetic field, the nuclear spins associated with hydrogen nuclei in tissue water become polarized, with the magnetic moments associated with ...

Problems solved by technology

However, conventional RF coils tend to be bulky, rigid and configured to remain in a fixed position relative to other RF coils in the array

This bulk and lack of flexibility often prevents the RF coil loops from coupling optimally with the desired anatomy and makes them very uncomfortable for the imaged subject

Additionally, coil-to-coil interactions dictate coil size and / or non-ideal positioning from a coverage or imaging acceleration perspective
