Abstract: An apparatus, including: a probe to interface with a surface of a tissue; a light source optically coupled to the probe, the light source directing light of at least 1000 nm into the tissue; a detector optically coupled to the probe, the detector to detect light based on scattering of light from the light source in the tissue, and the detector having a light sensitivity in a range of at least 1000 nm; a processor coupled to the detector, the processor to: receive a signal from the detector corresponding to the detected light from the light source, and determine a blood flow measurement from the region of interest using diffuse correlation spectroscopy based on the signal.

Abstract: Techniques are disclosed related to increasing prior limits imposed on MR gradient switching speed (dB/dt) without causing significant discomfort or severe pain perception to patients. The technique disclosed herein do so by modifying the pulsing gradient fields that are ordinarily available for MR imaging protocols. Doing so stimulates the peripheral nerves and thus enables a quick, reversible, and complete inhibition of action potential propagation through the stimulated region of tissue, referred to as a nerve conduction block.

Abstract: An imaging-based biomarker that indicates a neurological state of a subject is generated from magnetic resonance imaging data acquired from the subject while the subject was sleeping, or during both a sleep state and wake state. These magnetic resonance imaging data are acquired in such a way so that they simultaneously enable measurement of cerebrospinal fluid (“CSF”) flow and blood-oxygenation-level dependent (“BOLD”) signals. The imaging-based biomarker can be generated based on a correlation between CSF signals and BOLD signals extracted from these magnetic resonance imaging data. Using electroencephalography (“EEG”) data, CSF flow dynamics can also be estimated based on a physiological model in which coherent neural activity is modeled as entraining oscillations in blood volume and CSF.

Abstract: Systems and methods for designing parallel transmission radiofrequency (RF) pulses for use in a RF treatment. The methods include selecting a target region in a subject, and providing a plurality of specific absorption rate (SAR) matrices for estimation of SAR at locations within the subject. The methods also include determining a first set of SAR matrices for locations in the target region using the provided SAR matrices, and determining a second set of SAR matrices for locations not in the target region using the provided SAR matrices. The methods further include designing a plurality of RF pulses for achieving a target power deposition in the target region by using the first set of SAR matrices and the second set of SAR matrices in an optimization that determines a set of RF waveforms that produce a target average local SAR using the first set of SAR matrices while minimizing a local SAR and a global SAR using the second set of SAR matrices.

Abstract: A system acquires MR imaging data of a portion of patient anatomy associated with proton spin lattice relaxation time in a rotating frame using an RF (Radio Frequency) signal generator configured to generate RF excitation pulses and a magnetic field gradient generator configured to generate anatomical volume select magnetic field gradients for phase encoding and readout RF data acquisition. The RF signal generator and the gradient generator are configured to provide a rotating frame preparation pulse sequence comprising at least one of, (a) a T1 spin lattice relaxation in a rotating frame (T1?) preparation pulse sequence of adiabatic pulses comprising modulated RF pulses and modulated magnetic field gradients for slice selection and (b) a T2 spin-spin relaxation in a rotating frame (T2?) preparation pulse sequence of adiabatic pulses comprising modulated RF pulses and modulated magnetic field gradients for slice selection.

Abstract: An implant for deep brain stimulation (DBS) has an array of electromagnetic microcoils dispersed over the length of the implant. The microcoils produce magnetic fields that are directed into, and induce current in, the adjacent brain tissue. The microcoils may be selectively operated to direct and focus electrical stimulation to targeted areas of the brain. The implant is useful in studying or treating neurophysiological conditions associated with the deep regions of the brain such as Parkinson's disease, drug addiction, and depression.
