  • Swimming upstream on sound waves

    ETH researchers are among the first scientists to have succeeded in propelling microvehicles against a fluid flow using ultrasound. In future, these tiny vehicles are set to be introduced into the human bloodstream, thereby revolutionising the field of medicine. At some point, microvehicles that are more

  • Millimetre-precision drug delivery to the brain

    Researchers at ETH Zurich have developed a method for concentrating and releasing drugs in the brain with pinpoint accuracy. This could make it possible in the future to deliver psychiatric and cancer drugs and other medications only to those regions of the brain where this is medically desirable. T more

  • “Honey, I shrunk the detector”

    Researchers at Helmholtz Zentrum München and the Technical University of Munich (TUM) have developed the world’s smallest ultrasound detector. It is based on miniaturized photonic circuits on top of a silicon chip. With a size 100 times smaller than an average human hair, the new detector can visual more

Using Lung Ultrasound to Diagnose Pneumonia

Lung ultrasound may be a safe substitute for chest x-ray when diagnosing pneumonia in children. more

Ultrasound drug delivery

Using ultrasound waves, researchers have found a way to enable rapid delivery of drugs to the gastrointestinal (GI) tract. This approach could make it easier to deliver drugs to patients suffering from GI disorders. more

Definition

Ultrasound

Ultrasound Ultrasound is cyclic sound pressure with a frequency greater than the upper limit of human hearing . Although this limit varies from person to person, it is approximately 25 kilohertz (25,000 hertz) in healthy, young adults and th ... more
