Ultrasound Physical effects of ultrasound: 1- Thermal effects 2- Non-thermal effects 3- Effect of US in tissue repair First: thermal effect @ It is due to generation of heat within the tissue due to adsorption of US. @ Tissue with high amount of protein absorbs US more than other tissues. @ Generation of heat within the tissue will decrease pain‚ joint stiffness & increase blood flow. @ Thermal effect achieved if the temperature of the tissue is raised to 40°c - 45°c for at least

sonography also known as "ultrasound" was first attempted after WW2 using sonar equipment. But the electronics back then were too slow for the very short distances and high resolutions required for medical imaging. With the development of microchips‚ sonography has made huge advancements. Many individuals around the world have contributed to these incremental advances. The American Institute of Ultrasound in medicine was the first professional organization devoted to ultrasound. The AIUM began in 1951

Ultrasound technicians‚ or sonographers‚ generate diagnostic images for physicians through the use of high-pitched sound waves. These ultrasonic frequencies are affected by the density of the tissues they ’re travelling through‚ and computer processors inside the ultrasound unit interpret the echoes to create a visual image of the tissues. Sonography is one of the highest-paid professions open to those without a bachelor ’s degree. In its May 2011 Occupational Employment Statistics‚ the Bureau of

by research that any factors of health and care can be improved then it is. Researchers found that children are more vulnerable to radiation‚ which can increase the odds of them developing cancer later in life and therefore came up the idea for ultrasound scans to be used on children‚ rather than CT scans where they are exposed to unnecessary radiation. The researchers carried out a trial on 44 children with chronic liver problems‚ the test was able to accurately diagnose patients. Therefore‚ this

this and to design an ultrasound-enhanced process that would lead to homochirality in the absence of glass beads‚ we employed seeding during ultrasound-enhanced deracemization. We theorized that by introducing larger seed crystals to the system after the establishment of the monodispersed sized crystals (~2 hours)‚ we would broaden the crystal size distribution and thus allow the deracemization process to resume. To test this idea we performed seeded experiments using ultrasound‚ in which we introduced

realized that I was going to be a mother. I had scheduled my first ultrasound to see how my baby was growing and on that same day I found out that I was going to have a little boy on February 6‚ 2010. At that same ultrasound we discovered that my son’s left foot was clubbed. As a first time mom I went home and did as much research as possible on club foot. I was then referred to see a perinatal specialist whom did a number of ultrasounds and even performed an amniocentesis to test the chromosomes to

The Negative Effects of SONAR The world was first introduced to SONAR during World War II. It was originally created by the Navy‚ for military use. It has since been used for a number of other things. Many people argue the need for the use of his device because of its powerful effects. Even though sonar can be used for positive medicinal purposes and research applications‚ SONAR technology can have harmful effects on marine life‚ humans‚ and unborn children. To begin‚ SONAR has been used throughout
