Abstract: A further exemplary embodiment of the present disclosure can be, for example, a coil arrangement, which can include a loops including a plurality of first conductors extending in a first direction; a plurality of second conductors extending in a second direction, where the first direction is different from the second direction, and a plurality of linking points linking the first conductors to the second conductors, where the loop(s) can be configured to stretch in a third direction, and a perimeter of the loop is constant. The third direction can be different from the first and second directions, or it can be the same as the first direction or the second direction. The linking points can mechanically and pivotally connect the first conductors to the second conductors. The linking points can include flexible conductors, or the linking points can link the first conductors and the second conductors to a substrate. The substrate can be a trellis substrate.

Abstract: In a magnetic resonance (MR) apparatus and a method for operation thereof, the radio-frequency (RF) resonator of the scanner of the apparatus fed from a single RF source and is operated, during a total scan duration for acquiring MR scan data from a subject, so as to excite nuclear spins in the subject with respective RF fields having different B1+ field profiles that are radiated at respectively different times during the acquisition of the scan data. The scan data acquired during the scan thus are produced from MR signals caused by nuclear spins excited by at least two different B1+ field profiles. The scan can be used to acquire MR data for MR fingerprinting.

Abstract: An MRI rf coil array is comprised of a large number of separate coil elements that are supported on a substrate that is shaped to the contour of the anatomy being imaged. The coil elements overlap each other to reduce mutual inductance and their location is determined by tiling the surface of the substrate with regular, substantially same sized polygons. The center of each coil element is aligned with the center of a polygon. By using a mixture of different polygons, such as hexagons and pentagons, an arrangement of coil elements may be formed that cover a surface with non-zero Gaussian curvature where each coil is overlapped with its neighbors such that their mutual inductance is nulled.

Abstract: A multi-element MRI head coil is formed in the shape of a helmet that fits over the head of a subject to be imaged. The coil elements are separately driven by rf transmit channels during an MR scan to shape the rf fields produced in the region of interest. The head coil can be used in the transmit only phase of the scan, or it can be used in both the transmit and receive phases.
