• TRUS
  • A TRUS is often used to help diagnose prostate cancer if the prostate-specific antigen (PSA) level is high, the doctor feels an abnormal area during a digital rectal exam (DRE) or a man has certain symptoms, such as trouble urinating. (cancer.ca)
  • prostate cancer
  • Smith worked on a three-year postdoctoral fellowship with Professor Kullervo Hynynen in the Radiology Department at Brigham and Women's Hospital, Harvard Medical School, where she developed an intracavitary ultrasound hyperthermia array used for human prostate cancer treatments. (wikipedia.org)
  • Doppler
  • locating said uterine artery with a locating device selected from the group consisting of a CT scanner, a fluoroscope, X ray, a MRI device, Doppler audio device, a gray scale color 2D Doppler ultrasound device, a landmark system, and combinations thereof. (google.com)
  • occur
  • Current sheets occur in many different situations, and observationally they give rise to specific localised signatures such as significant plasma heating, systematic high velocity plasma flows, and accelerations of a population of particles to relativistic energies. (prace-ri.eu)
  • surgery
  • Focus Surgery, Inc. (google.com)
  • She collaborated with Focus Surgery, Inc., the makers of the Sonoblate®500 and with Piezo Resonance Innovations (now Actuated Medical, Inc.) on SBIR funding from the National Institutes of Health. (wikipedia.org)
  • humans
  • It is a fact in psychoacoustics that children can hear some high-pitched sounds that older adults cannot hear, because in humans the upper limit pitch of hearing tends to become lower with age. (bionity.com)
  • Ultrasound is no different from 'normal' (audible) sound in its physical properties, except in that humans cannot hear it. (wikipedia.org)
  • Francis Galton in 1893 invented the Galton whistle, an adjustable whistle which produced ultrasound, which he used to measure the hearing range of humans and other animals, demonstrating that many animals could hear sounds above the hearing range of humans. (wikipedia.org)
  • processes
  • The formation of electric current sheets therefore signals the onset of explosive energy release processes, and a detailed understanding of the conditions for forming current sheets is needed to understand where, when and why such explosive events form. (prace-ri.eu)
  • small
  • Depending on the design of the lens and the ultrasound parameters, the target can be as small as 1 x 1.5 mm or as large as 10 x 16 mm in diameter. (itnonline.com)
  • Where the streams of energy intersected at the prostate, the temperature soared to more than 80 C, cooking small batches of tumor cells in seconds. (paete.org)
  • The wild ancestors of cats and dogs evolved this higher hearing range to hear high-frequency sounds made by their preferred prey, small rodents. (wikipedia.org)
  • control
  • Ultrasound generator/speaker systems are sold as electronic pest control devices, which are claimed to frighten away rodents and insects, but there is no scientific evidence that the devices work. (wikipedia.org)
  • areas
  • Samples are taken from different areas of the prostate including any areas that look abnormal on the ultrasound. (cancer.ca)
  • include
  • Other factors that may be involved include a diet high in processed meat, red meat, or milk products or low in certain vegetables. (wikipedia.org)
  • method
  • 7. The method of claim 1 wherein applying the high-frequency output includes forming the cavity such that the urethral passage is enlarged relative to a normal size of the urethral passage. (google.com)
  • 8. The method of claim 1 wherein applying the high-frequency output includes applying the high-frequency output through the ring electrode to a return electrode. (google.com)
  • Scientist are also studying ultrasound using graphene diaphragms as a method of communication. (wikipedia.org)
