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

Embodiment Construction

[0024] The following description relates to various embodiments of radio frequency (RF) coils in an MRI system. In particular, systems and methods are provided for low cost, flexible and lightweight radio frequency coils that are effectively transparent in multiple respects. Considering the low weight of the coil and the flexible packaging achieved by the RF coil, the RF coil is effectively transparent to the patient. The RF coils are also effectively transparent to other RF coils in the RF coil array due to the minimization of magnetic and electrical coupling mechanisms, which allows the incorporation of coils into stretchable coil arrays. Furthermore, RF coils are effectively transparent to other structures through capacitance minimization and to positrons through mass reduction, enabling the use of RF coils in hybrid positron emission tomography (PET) / MR imaging systems. The radio frequency coils of the present disclosure can be used in MRI systems of various magnetic fiel...

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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 425,975, filed November 23, 2016, entitled "SYSTEMS FOR A RADIO FREQUENCY COIL FOR MR IMAGING," which The entire contents are hereby incorporated by reference for all purposes. technical field [0003] Embodiments of the subject matter disclosed herein relate to magnetic resonance imaging (MRI), and more particularly, to MRI radio frequency (RF) coils. 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 ...
