Devices, systems, and methods for ultrasonically acquiring far-field and near-field images within a body are disclosed. An ultrasound imaging device adapted for insertion within a body includes a first ultrasonic sensor configured to transmit ultrasonic waves at a first frequency for acquiring far-...
Fast computation of far-field pulse-echo PSF of arbitrary arrays for large sparse 2-D ultrasound array design 2018, Ultrasonics Citation Excerpt : Therefore, in many researches [11,12] narrowband beam pattern (BP) has been chosen as the evaluation tool for designing narrowband arrays of antennas...
In the sub-MHz ultrasound domain, the resulting radiation force causes the particles to assemble at the pressure antinodes along concentric circles corresponding to the Bessel profile. By imposing an axial confinement in the evanescent region, the subwavelength two-plate sandwich system becomes resonant...

The formation of an occlusive thrombus in the blood vessel is the main culprit for numerous life-threatening cardiovascular diseases that represent the leading cause of morbidity and mortality worldwide. Herein, we develop a polymer nanoplatform that int
Every class has a specific result designed to prepare you to succeed in the field. The school has top-tier facilities, run under the guidance of Hampden Engineer trainers. North Michigan University – HVACR Program NMU is based in Marquette, MI, and offers an HVAC & Refrigeration program. Unl...
In contrast, modulation of neural activity by physical stimulus (e.g., electric current, magnetic field, and ultrasound) offers the unique advantages of strong accessibility and controllability. For instance, with the assistance of magnetic nanoparticles (MNPs), alternating magnetic field could excite ...
Liposomal release based on heating to lipid phase-transition temperatures has been expanded to other thermal transduction methods including ultrasonic tissue heating14, magnetic field heating using magnetoliposomes15,16 and near-infrared (NIR) photothermal heating via gold coating17,18, tethering19 and ...
Smart drug delivery systems (SDDSs) for cancer treatment are of considerable interest in the field of theranostics. However, developing SDDSs with early diagnostic capability, enhanced drug delivery and efficient biodegradability still remains a scientif
