Veterinary Ultrasound Applications - When someone hears the word “ultrasound”, they probably immediately think babies, pregnancy, and those fuzzy black and white computer screens displaying the picture of a developing fetus. Modern medicine has now gone much further than those often grainy flat images a mother used to see. Three dimensional and even 4-D imaging is possible, and not only in medical facilities, but in veterinary clinics. Only a few universities were using this technology in the 1970 and 1980s, but today, modern advancements and availability allows clinics to depend on this technology for all kinds of cases....   [tags: ultrasound, technology,clinics]

The Physics of Ultrasound - Without the use of physics in the medical field today, diagnosis of problems would be challenging, to say the least. The world of medical imaging in particular has benefited greatly from the use of physics. Ultrasound is sound waves that have a frequency above human audible. (Ultrasound Physics and Instrument 111). With a shorter wavelength than audible sound, these waves can be directed into a narrow beam that is used in imaging soft tissues. As with audible sound waves, ultrasound waves must have a medium in which to travel and are subject to interference....   [tags: Physics, Ultrasounds, medical, ] 892 words

Ultrasound Technology - What is Ultrasound. Ultrasound or ultrasonography is a medical imaging technique that uses high frequency sound waves. It is a high pitch frequency that cannot be heard by the human ear. In ultra sound the following happens: High frequency sound pulses (1-5megahertz) are transmitted from the ultrasound machine into your body using a probe. The sound wave will travel into your body until it hits an object such as soft tissue and bone. When the sound wave hits these objects some of the wave will be reflected back to the probe....   [tags: Ultrasonography Medical Imaging] 1525 words

Radiation and Its Uses, Specifically in South Africa - What is radiation. Radiation is energy that comes from a source and travels in the form of waves or high speed particles. Radiation is mainly released from atoms, which is the smallest particle of matter. When radiation is emitted, it excites the orbiting electrons in atoms and causes the electrons to vibrate, which emits the energy. There are two types of radiation, namely Ionizing radiation and non-ionizing radiation. Non- ionizing radiation has a low energy level and therefore cannot change the chemical properties of a substance that it is exposed to....   [tags: Ionization, Energy, Cancer] 1923 words
