  • Spherical Array System for High-Precision Transcranial Ultrasound Stimulation and Optoacoustic Imaging in Rodents
    Posted on January 1, 2021 at 12:00 am

    Ultrasound can be delivered transcranially to ablate brain tissue, open the blood–brain barrier, or affect neural activity. Transcranial focused ultrasound in small rodents is typically done with low-frequency single-element transducers, which results in unspecific targeting and impedes the concurrent use of fast neuroimaging methods. In this article, we devised a wide-angle spherical array […]

  • S-MRUT: Sectored-Multiring Ultrasonic Transducer for Selective Powering of Brain Implants
    Posted on January 1, 2021 at 12:00 am

    One of the main challenges of the current ultrasonic transducers for powering brain implants is the complexity of focusing ultrasonic waves in various axial and lateral directions. The available transducers usually use electrically controlled phased array for beamforming the ultrasonic waves, which increases the complexity of the system even further. In this article, we propose a straightforward […]

  • Spatial Response Identification for Flexible and Accurate Ultrasound Transducer Calibration and its Application to Brain Imaging
    Posted on January 1, 2021 at 12:00 am

    Accurate wave-equation modeling is becoming increasingly important in modern imaging and therapeutic ultrasound methodologies, such as ultrasound computed tomography, optoacoustic tomography, or high-intensity-focused ultrasound. All of them rely on the ability to accurately model the physics of wave propagation, including accurate characterization of the ultrasound transducers, the physical […]

  • Lamb Waves and Adaptive Beamforming for Aberration Correction in Medical Ultrasound Imaging
    Posted on January 1, 2021 at 12:00 am

    Phase aberration in transcranial ultrasound imaging (TUI) caused by the human skull leads to an inaccurate image reconstruction. In this article, we present a novel method for estimating the speed of sound and an adaptive beamforming technique for phase aberration correction in a flat polyvinylchloride (PVC) slab as a model for the human skull. First, the speed of sound of the PVC slab is found […]

  • Guest Editorial Introduction to the Special Issue on Recent Advances in Ultrasound Technology for Brain Imaging and Therapy
    Posted on January 1, 2021 at 12:00 am

    The emergence of new technologies has dramatically accelerated our understanding of the human brain function. Over the past decade, ultrasound has become a valuable tool in preclinical animal studies and clinical practice in many areas of the brain. This is because it can not only provide information about the structure and function of brain tissues but also constitute a potential treatment tool […]

  • A High-Frequency Phased Array System for Transcranial Ultrasound Delivery in Small Animals
    Posted on January 1, 2021 at 12:00 am

    Existing systems for applying transcranial focused ultrasound (FUS) in small animals produce large focal volumes relative to the size of cerebral structures available for interrogation. The use of high ultrasonic frequencies can improve targeting specificity; however, the aberrations induced by rodent calvaria at megahertz frequencies severely distort the acoustic fields produced by […]

  • Ultrasound for the Brain: A Review of Physical and Engineering Principles, and Clinical Applications
    Posted on January 1, 2021 at 12:00 am

    The emergence of new ultrasound technologies has improved our understanding of the brain functions and offered new opportunities for the treatment of brain diseases. Ultrasound has become a valuable tool in preclinical animal and clinical studies as it not only provides information about the structure and function of brain tissues but can also be used as a therapy alternative for brain diseases. […]

  • Real-Time Passive Acoustic Mapping Using Sparse Matrix Multiplication
    Posted on January 1, 2021 at 12:00 am

    Passive acoustic mapping enables the spatiotemporal monitoring of cavitation with circulating microbubbles during focused ultrasound (FUS)-mediated blood–brain barrier opening. However, the computational load for processing large data sets of cavitation maps or more complex algorithms limit the visualization in real-time for treatment monitoring and adjustment. In this study, we implemented […]

  • Transcranial Focused Ultrasound for Noninvasive Neuromodulation of the Visual Cortex
    Posted on January 1, 2021 at 12:00 am

    Currently, blindness cannot be cured and patients’ living quality can be compromised severely. Ultrasonic (US) neuromodulation is a promising technology for the development of noninvasive cortical visual prosthesis. We investigated the feasibility of transcranial focused ultrasound (tFUS) for noninvasive stimulation of the visual cortex (VC) to develop improved visual prosthesis. tFUS was […]
