"A history of ultrasound physics and the properties of the transducer"

Download file to see previous pages Prior to the second World War, sonar, which is the technique of transmitting waves of sound through water and observing the echoes that return to characterize the objects that are submerged, was an inspiration to the pioneers of ultrasound investigators in exploring ways and in turn applying the medical diagnosis concepts. This paper will highlight the history of ultrasound and discuss the properties of transducers.
History of ultrasound
According to Orenstein, (2008) Pythagoras, popular for his theory about right-angled triangles was the pioneer of ultrasound, since he invented the sonometer, which was used to study musical sounds. Boethius (c. 480-c.525) was the first to give comparison between sound waves to waves that were produced when a pebble was dropped into calm water. Pierre Curie, a French physicist discovered piezoelectricity in 1877, the moment that ultrasound was conceived. Later on, as Orenstein continues to assert, sonographic imaging was developed by French professor and physicist Paul Lavengin. Many scientists had the desire to see inside the human body and in turn developed probes and scopes for diagnosis and treatment during the late 19th and early 20th centuries. For instance, the discovery of X-rays by William Conrad in 1865 played an important role in the history of ultrasound. Moreover, in 1912, when the Titanic sank while on its maiden voyage made people to be curious in detecting submerged substances. Like many other technological advances, ultrasound also owes its development to the World War. Lavengin was called upon by the French government to develop an object that was able to detect the sub marines of the enemy during the World War One. The device he invented applied the piezoelectric effect he had learned as Curies’ student (Orenstein, 2008). The transducer is one of the most critical componenets of any diagnostic ultrasound system. There exists various types of ultrasound transducers that can be chosen prior to performing an ultrasound investigation, therefore, much attention should be accorded towards choosing the most suitable transducer for the ultrasound application (Gibbs, Cole, & Sassano, 2009 p27). However, Lavengin did not complete the device he developed in 1917 so that it could be used during the First World War, but it indeed formed the basis of sonar detection that was developed in the World War II (Orenstein, 2008). In 1928, Sergei Sokolov, a Russian physicist made important suggestions that saw ultrasound being used for industrial purposes that included detecting flaws in metallic devices. Ultrasound is a new aspect in the field of medicine. For instance, in the 1920s and the 1930s, ultrasound was used by members of European football clubs as a physical therapy. Additionally, as reported by Orenstein, ultrasound was utilized in the sterilization of vaccines as well as for cancer therapy in conjunction with radiation therapy. Subsequently, in 1948, other ultrasound pioneers such as Douglas Howry subjected his efforts towards developing a B-mode equipment that compared pathology to cross-sectional anatomy. The late 60s and early 70s was the period of sonic boom. A 2D echo was pioneered by Klaus Bom. Don Baker, John Reid and Dennis Watkins were able to develop a pulsed Doppler in 1966, which was able to detect the flow of blood from the different corners of the heart. Real-time ultrasound was developed in ...Download file to see next pagesRead More

This research paper was always my weak point. I could never complete it well. Still, after I found this particular paper, I understood how it should be done. So, I performed my research afterward and completed the research paper in several hours, instead of weeks as it was previously.

The Physics of Ultrasound
It has been much widely known to the public due to its ease of use as well as being able to generate rapid image analyses (Gill 1). The beginnings of ultrasound imaging can be traced to the pursuits of the mining industry, wherein certain metals can be detected due to the differences between the densities of the layers that the sound waves pass through, and these differences were able to identify if the ground being scanned is pure rock or not (Hoskins 1).

The physical principles underlying ultrasound solely are founded on the frequency of sound transmission. In the study of ultrasound, keen reflection is dedicated to the behavior of sound when transmitted in different media. The most prevalent media used are water and air which are easy to work with.

Ultrasound Technician Profession
He or she carries out processes that are often similar those carried out using X-ray machines (Mitchell and Haroun, 2011). Better stated, an ultrasound technician creates medical imaging of the human body using the device. Such imaging in the human body includes the spinal cord, the abdominal area, the brain, eyes and the correlating muscles.

Ultrasound Treatment of Tremors and Parkinson's Disease
Its prevalence increases with age, and is highest,at around 4%, in individuals above 85 years of age (10). Its pathophysiology involves degeneration of the dopamine-secreting neurons of the substantia nigra, a nucleus in the midbrain. These neurons are normally responsible for an inhibitory and/or excitatory effect on the basal ganglia neurons that control movement; the loss of dopaminergic neurons leads to instability of movement.

But it gained an independent identity in 19th century. New discoveries constantly open new outlook for learning about nature. It is a way of looking at nature from the ground up, and has inspired the philosophies of the twentieth century. Today, the scope of physics is expanding through inter-relationship between various concepts like mechanics, heat, sound, light, electricity and magnetism leading to new fields including microbiology, nano- technologies and financial markets
