Methods for forming conformal magnetic resonance imaging (MRI) receive coil devices having at least one receive coil with at least one capacitor are provided and include providing a 3-dimensional (3D) mold structure matching a curvilinear shape of interest, and forming a receive coil pattern on an outer surface of the 3D mold structure. The forming of the receive coil pattern may include spraying and/or depositing a conductive material and a dielectric material on the outer surface of the mold structure to form the receive coil pattern. The forming a receive coil pattern may include forming the receive coil pattern on an outer surface of a flat substrate sheet, and vacuum forming an inner surface of the flat substrate sheet to the outer surface of the mold structure to form a shape-conforming substrate sheet. The shape-conforming substrate sheet may be removed from the mold and used in MRI studies.

Systems and methods for fabricating conformal magnetic resonance imaging (MRI) receive coils

Methods for forming flexible magnetic resonance imaging (MRI) receive coil devices having at least one receive coil with at least one capacitor are provided and include providing a flexible substrate having a first surface and a second surface opposite the first surface, forming a first conductor pattern on the first surface by printing a first layer of conductive material on the first surface using a printing mask having a pattern, and forming a second conductor pattern on the second surface by printing a second layer of conductive material on the second surface using the same printing mask or identical printing mask, wherein a portion of the first conductor pattern on the first surface overlaps with a portion of the second conductor pattern on the second surface with the flexible substrate therebetween to form the at least one capacitor element.

Single screen fabrication of symmetric multilayer magnetic resonance imaging (MRI) receive coils

A method for MRI imaging of a subject includes spatially encoding spins in a slice of the subject in orthogonal first and second directions. The encoding includes applying a chirped radiofrequency (RF) pulse concurrently with application of a magnetic field gradient pulse along the first direction. After applying of the RF pulse, a second chirped RF pulse is applied concurrently with application of a second magnetic field gradient pulse, with polarity opposite that of the first gradient pulse. An encoding magnetic field gradient, constant from applying the first RF pulse until the end of applying the second RF pulse, is concurrently applied along the second direction. Following the encoding, a spin signal is measured concurrently with application of a constant readout magnetic field gradient.

Cross-term spatiotemporal encoding for magnetic resonance imaging

In a volumetric fast spin-echo magnetic resonance imaging system a plurality of radio frequency pulses can be emitted. The plurality of radio frequency pulses can be directed toward a target sample. The plurality of radio frequency pulses can have a set of repetition times. The set of repetition times can define a frequency at which the plurality of radio frequency pulses are emitted. The set of repetition times can be varied during the emitting of the plurality of the radio frequency pulses. Magnetic resonance imaging data of a target sample can be received. A pseudo-random sampling pattern can be used to facilitate the receiving of the magnetic resonance imaging data having multiple magnetic resonance imaging contrasts for a single scan.

Multi-contrast images from a magnetic resonance imaging scan

A Magnetic Resonance Imaging (MRI) receiver includes a receiver coil on a substrate. The receiver coil includes one or more capacitors. The construction of the capacitors allows for the use of very flexible substrates and allows the capacitors themselves to be highly flexible. The increased flexibility permits the MRI receiver to be conformed to the body of a patient and accordingly improves the MRI process.
