Scientists currently use long-wave pulses of ultrasound to deliver drugs, which can cause side effects. These new findings from Imperial on shorter-wave pulses could have implications for how drugs ...

Biomedical engineers at Johns Hopkins report they have worked out a noninvasive way to release and deliver concentrated amounts of a drug to the brain of rats in a temporary, localized manner using ...

BOSTON — Use of power-matrix pulsed phacoemulsification reduces the total energy and time to remove the nucleus, according to a study that compared pulsed ultrasound with continuous ultrasound using ...

The blood-brain barrier is a protective layer that surrounds the brain. Its main function is to prevent potentially harmful agents from leaking into this organ. However, it can also stop certain ...

Intracranial ultrasound treatment using an operator-independent device together with tissue plasminogen activator (tPA) in stroke patients appears to be safe and produced promising recanalization ...

Both ultrasound for medical imaging and seismology for imaging the Earth's interior measure the propagation of waves through matter. For example, when seismic waves encounter material differences in ...

High-frequency ultrasound platform for preclinical imaging, supporting real-time visualization of small animal anatomy and ...

Background: The effect of low-intensity ultrasonography on fracture healing is controversial, and current management of fractures does not generally involve the use of ultrasound therapy. We describe ...

Developed instrumentation and transducers for noninvasive measurement of central (1992) and regional (1996) flow velocity, and aortic pulse-wave velocity (1997) in mice Developed the first ultrasonic ...
