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

Use of PET for the Detection of Cancer - Prostate cancer imaging with 18F-fluorocholine A combination of prostate-specific antigen (PSA) testing and transrectal ultrasound-guided biopsy is generally used for the detection of prostate cancer [17].

In addition, postradiotherapy prostate biopsies are prone to problems in interpretation (due to the presence of radiation effects and the lack of knowledge of the time required for residual tumour to become nonviable after radiation [20]) and transrectal ultrasound-guided sextant biopsy typically understages disease in patients with...   [tags: Prostate cancer imaging] 1592 words
