Many clinicians routinely use multiple receive coils for magnetic resonance imaging (MRI) studies of the human brain. In conjunction with these exams, it is often desired to perform proton magnetic resonance spectroscopy (MRS) experiments to quantify metabolites from a region of interest. An MRS

Furthermore, by casting the FOV reduction of parallel imaging techniques as a dimensionality reduction of the kspace that is non

Abstract. Inductive powering can free microelectromechanical systems (MEMS) devices from tethering to a power supply, thus expanding their scope of applications. We investigate inductive powering for MEMS using a microfabricated coil as a receiver operating at and below 1 MHz. The microcoil

of MR image acquisition and processing parameters. In its current form, this noise model requires the accurate estimation of image SNR. For multi-channel receiver coils, this is not straightforward because it requires export and reconstruction of large amounts of k-space raw data and detailed, custom

An 8-channel receive-only detector array was developed for SENSE MRI of human brain. The coil geometry was based on a gapped element design and used ultra-high impedance preamplifiers for mutual decoupling of the elements. Computer simulations of the electric and magnetic fields showed

Two eight-channel MRI receive-only coils were developed to provide whole-brain coverage at 1.5 T and 3.0 T field strength, respectively. Objectives were an image signal-to-noise ratio superior to standard designs throughout the human brain, as well as high parallel imaging performance. Electro

High quality pictures with good resolution are of crucial importance in magnetic resonance imaging (MRI). Due to the relative low intrinsic sensitivity of the MR-technology there are high demands on the specific hardware equipment. The technical design of the radio frequency (RF) coils is one

Integrating neurosurgery with intraoperative-MRI has presented technical challenges involving the scanner and ancillary equipment. In the past few years, many challenges have been met. The foundation now exists that will allow this new discipline to expand the limits of neurosurgery.
