Ultrasound Therapeutic Effect

In 1801 Thomas Young described “phase shifting” in relation to light. Christian Doppler in 1842 created the “Doppler effect” which is how blood flows in pelvic vessels and the fetus. Pierre Curie in 1880 described the piezoelectric effect, where ceramic to generate ultrasonic waves.Paul Langevin in 1915 built the first hydrophone, microphone designed to be used to listen to underwater sound ,also related to measurement of the fetus and abdominal masses. Watson-Watt developed the radar in 1943 using electromagnetic waves. John Read published the first 2D images in 1952. 3D ultrasound was first developed by Olaf von Ramm and Stephen Smith in 1987.

Diagnostic medical sonography is a profession where sonographers direct high-frequency sound waves into a patient’s body through use of specific equipment to diagnose or monitor a patient’s medical condition. As described by the Bureau of Labor Statistics, this examination is referred to as an ultrasound, sonogram, or echocardiogram. The high-frequency sound waves emitted from the handheld device, called a transducer, bounce back creating an echo and therefore produce an image that can be viewed on the sonographers computer screen. This image provides the sonographer and physician with an internal image of the patient’s body that will be used in diagnosis. The most familiar use of ultrasound is used in monitoring pregnancies, and is

The first technique I will suggest to use is Ultrasound. Because it is one of the safest to use and it does not use any radiation that would affect her from having children in the future. Furthermore, the evidence to support this idea of using an Ultrasound is because it only uses high frequency sound waves to create an image that will then be shown on video screen. Ultrasound also uses a device called transducer that contributes sound waves and grasp the echoes as they bounce off the organs. This echoes will then be improved by a computer into black and white images. This procedure can show masses of tumours growing in the liver, which can be tested for cancer.

Ultrasound relies on high frequency sounds to image the body. As stated above, ultrasound are produced by an ultrasound transducer. To produce ultrasound, a piezoelectric crystal has an alternating current applied across it, this causes the crystal to vibrate at a high speed and to produce ultrasound as it converts electrical energy to mechanical energy in sound waves. This sound wave bounces off the object being scanned. This sound triggers the piezoelectric crystal and has its affects reversed. By measuring the time taken to send and receive the sound the computer can produce images. Ultrasound poses no health risks while x rays give off varying degrees of radiation. Exposure to radiation can have long term health although the rates are very low.

Medical ultrasound (also known as diagnostic sonography or ultrasonography) is an diagnostic imaging technique based on the application of ultrasound. It is used to see internal body structures such as tendons, muscles, joints, vessels and internal organs. The aim of often to find a source of a disease or to exclude any pathology. The practice of examining pregnant women using ultrasound is called obstetric ultrasound, and is widely used.

The first practical ultrasound machine was developed in 1973 by the help of a Scottish mountaineer and physiologist named Thomas Graham Brown in Glasgow, who elaborated in a Multiplanar scanner, under the Sonicaid Ltd. With improvements in ultrasonic and computer technology, work on three-dimensional visualization began to appear in the early 1980's. The first person

There is a lot of history relating to ultrasound or another name is sonography. It has come very far for the uses in not only medical situations but other technological situations. Ultrasound has been seen to dates back to the 1700’s. The first inventor known to study ultrasound is Lazzaro Spallanzani in 1794. He was a physiologist to first study ultrasound physics by using bats. Bats use echolocation, which are sound waves that travel in the air till they hit an object and bounce back to the bat so it can in a sense see what is around him by knowing how long the wave took to get back. Ultrasound works similarly to bats echolocation. It uses high frequency sound waves that capture live images from inside the body. This works like how a bat can see with soundwaves but be almost blind. The next person Karl Dussik, physicist was the first doctor to use ultrasound as an instrument for diagnosis called it Hyperphongraphy. They used this to try and locate brain tumors with one transducer on side of the skull

I am sorry for your loss .It is common to experience cramping and spotting for few days after the procedure. It should usually slow down over a time. What point of concern here is, bleeding stopped and started again. Follow up ultrasound is very important after D&C to confirm that procedure is completed. There are chances that bit of placenta continue to stick to uterus and drew a little bit fresh blood.

Another form of imaging is ultrasound. Ultrasound, which uses very high frequency sound, is directed into the body. And because the tissue interference's reflect sound, doctors are able to produce, by use of a computer, a photograph or moving image on a television. Ultrasound has many application uses on the body, but is more commonly used in examinations of the fetus during pregnancy, because use of radiation may affect the outcome of the baby. Some other practices for ultrasound include examination of the arteries, heart, pancreas, urinary system, ovaries, brain, and spinal cord. And because sound travels well through fluids it is a very useful technique for diagnosing cysts( which are filled with fluid), and fluid filled structures such as the bladder. And since sound is absorbed by air and bone it is impossible to use a ultrasound on bones or lungs.

Radiation is energy passed through waves, space or matter. Thinking about energy being passed through matter is pretty scary especially to pregnant women. It is very common for women to take precautions during pregnancies. The energy from the radiation can cause damage to one's fetus, and can be very harmful to a child. Luckily in this day and age, there are machines and safeguards against radiation. In the case of a pregnant woman those safeguards are for Ultrasounds. This procedure uses sound waves to create images of a woman's body using a transducer probe. A safe and painless exam producing no radiation exposure.

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. While some waves may carry on further till they hit another object and then reflected back. The probe picks up these reflected sound waves and relays them to the machine. The distance and time from the probe,

When asked what is ultrasound many people may give answers such as, “Oh that’s when they scan women who are pregnant to see the baby”, but little do people know that ultrasound is much more then that. Not only do people misunderstand the job description but also the salary that comes along with the career. Both job description and salary are based on the specialty you choose to pursue. Ultrasound is a very diverse field with many different specialties to choose from within the field and each specialty has a specific salary along with it depending on the state you live in.

Ultrasound treatment was done according to method by [21] with some modifications. Ultrasonic probe (JY92-IIN, Ningbo Scientz Biotechnology Co. Ltd, Ningbo, China) was used, with maximum power 1000Watt, frequency 25 kHz and probe diameter of 13mm. Pectin solutions were treated at 60% duty cycles, sonication times was fixed at 20 minutes, sonication power (200 and 400 watts). Effect of acidity on sonication was determined at pH 2, 4 and 6, by adjusting solution pH using acetic acid. Native pectin 0.25g was put in 250ml beaker suspended in 100ml deionized water to achieve low viscosity, it was stirred on a magnetic stirrer for 30 minutes, and sonic treatment was done by immersing sonic probe up to 1cm deep in the solution. After treatment, the suspension was precipitated with equal volume of 95%v/v ethanol to precipitate pectin. The content was centrifuged at 7500xg and filtrate removed. the precipitate was left in fume cupboard to remove ethanol traces then re-dissolved in deionized water and frozen at -45ᴼC and eventually freeze dried for further analysis. Ultrasound intensity was predicted according to the following equation
