Embodiment Construction

[0023] The embodiments described herein will be better understood when read with the accompanying figures. To the extent that the figures illustrate diagrams of the functional blocks of various embodiments, the functional blocks are not necessarily indicative of the division between hardware circuitry. Thus, for example, one or more functional blocks (eg, processor, controller, or memory) may be implemented in a single piece of hardware (eg, a general-purpose signal processor or random access memory, hard disk, etc.) or in multiple pieces of hardware. Similarly, a program may be a stand-alone program, incorporated as a subroutine in an operating system, a function in an installed software package, etc. It should be understood that the embodiments are not limited to the arrangements and instrumentalities shown in the drawings.

[0024] As used herein, an element or step recited in the singular and proceeded with the word "a" should not be understood as excluding plural of said...

Abstract

The invention is named method and apparatus for imaghing a subject using local surface coils. A Radio Frequency (RF) coil apparatus (10) for generating a magnetic resonance (MR) image includes a main body (12) adapted to be worn by a subject being scanned, wherein the main body comprises an anterior portion (20), a posterior portion (22), and a transition portion (24) coupled between the anterior and posterior portions; a first RF receive-only saddle coil (100) includes a first coil (110) positioned in the anterior portion and a second coil (112) positioned in the anterior portion, the first RF saddle coil configured to be positioned on the anterior and posterior sides of the subject. An MRI imaging system (200) and method are also described herein.

Description

technical field [0001] The subject matter disclosed herein relates generally to magnetic resonance imaging (MRI) systems, and more particularly to methods and devices for imaging a subject using local surface coils. Background technique [0002] MRI or Nuclear Magnetic Resonance (NMR) imaging typically provides spatial discrimination of resonant interactions between radio frequency (RF) waves and nuclei within a magnetic field. Specifically, MRI utilizes the hydrogen nuclear spins of water molecules in the human body, which are polarized by the strong, uniform, static magnetic field of a magnet. This magnetic field is usually referred to as B 0 or the main magnetic field. When a substance (such as human tissue) is subjected to a main magnetic field, the individual magnetic moments of the spins in the tissue try to align with the main magnetic field. When excited by an RF wave, the spins precess about the main magnetic field at the characteristic Larmor frequency. The sig...
