Some radio-frequency coils comprise three or more electrical conductors that form a radio-frequency coil element. Each of the three or more electrical conductors extends along at least a respective part of a length of the radio-frequency coil element, and, along the length of the radio-frequency coil element, the three or more electrical conductors are separated from each other by respective distances and by one or more dielectric materials.

A drive mechanism for a vacuum cleaner having a motor and an agitator includes a belt coupled to the motor and the agitator to drive the agitator, and a belt tensioner operable to selectively tension the belt. The belt tensioner includes an arm movable relative to the belt, a shaft coupled to the arm, a pulley rotatably coupled to the shaft, a bearing positioned substantially within the pulley and around a portion of the shaft, and a member fixed to the pulley to retain the bearing within the pulley.

A radio frequency (RF) coil array includes a plurality of RF coil sections arranged in a superior-inferior direction. Each RF coil section includes a first linear coil element, a loop-saddle coil quadrature pair and a second linear coil element configured in an overlapping arrangement in a left-right direction. The position of the first linear coil element and the second linear coil element on the left and right may be shifted in the superior-inferior direction with respect to the center loop-saddle coil quadrature pair.

The present invention relates to a design of a radiofrequency (RF) receive coil (also commonly referred to as an imaging coil) for magnetic resonance imaging (MRI) in a vertical field MRI system of a patient's breast region. The design described herein generally includes a housing that includes two coil cups. The coil housing will generally encase the coil elements. In general, the breast coil of certain embodiments of the invention will include loop elements surrounding each side of each of the coil cups, a saddle element at the bottom of each cup, and an element that spans the width of the coil, wrapping at least partially up both sides of the coil. It is foreseen that further embodiments of the breast coil design may include additional elements.

The present invention relates to an element configuration within an RF coil for use for MRI. The invention provides for an inherently electromagnetically decoupled solenoid element pair for receiving radio frequency magnetic resonance signals within a vertical field MRI system. The elements of the solenoid element pair described herein are typically positioned in a coplanar, side-by-side position. The decoupling of the solenoid pair can be accomplished through numerous methods including but not limited to an overlapping between the elements of the solenoid pair, use of a capacitor shared between the elements of the solenoid pair, or the use of overlapped inductors between the elements of the solenoid pair.

The present invention relates to a design of a radiofrequency (RF) receive coil (also commonly referred to as an imaging coil) for magnetic resonance imaging (MRI) in a horizontal field MRI system of a patient's shoulder region.

Horizontal field MRI shoulder coil

The present invention relates to a design of a radiofrequency (RF) receive coil (also commonly referred to as an imaging coil) for magnetic resonance imaging (MRI) in a vertical field MRI system of a patient's shoulder region. The design described herein generally includes a solenoid element that wraps around the patient's shoulder, at least two loop elements that encompass the superior section of the patient's shoulder, and at least two saddle elements, wherein one saddle element encompasses the posterior section of the patient's shoulder and one saddle element encompasses the anterior section of the patient's shoulder. It is foreseen that further embodiments of the shoulder coil design may include additional elements.
