¶ … History of Ultrasound Physics and the Properties of the Transducer
Today, innovations in medical imaging allow clinicians to view the soft tissues, organs and blood flow inside the human body in ways that provide the opportunity for early diagnosis and treatment of a wide range of disorders as well as to monitor neonatal health (Goldberg & Verny, 2007). The introduction of ultrasound technologies, though, has only taken place since the second half of the 20th century, although there were a number of earlier attempts in the late 19th century that met with limited success. To determine the facts about this important innovation, this paper reviews the relevant literature concerning the history of ultrasound physics and the properties of the transducers that are used for ultrasound imaging, followed by a summary of the research and important findings concerning these issues in the conclusion.
Review and Discussion
According to Levine (2010), ultrasound is defined as "[S]ound with frequencies above 20 kHz (twenty thousand cycles per second)" (p. 179). Ultrasound physics relate to a physical or electromagnetic wave that is capable of interacting with some type of object; the extent of the interaction, or the crests and waves that are created, is a...
This also serves as an important catalytic effects for the bonding of mothers to their babies even before they are born. It is also called the "re-assurance scans" and misnamed as "entertainment scans." Some specialists do not recommend 3-D and 4-D ultrasound as manadatory development of the conventional 2-D scans. Although these may play a part in the study of fetal embryology. There were many researches done on the in-vitro
Very near the beginning of World War II, Karl Dussik began exploring ultrasound technology for diagnostic purposes by "attempted to locate brain tumors and the cerebral ventricles by measuring the transmission of ultrasound beam through the skull" (Woo 7). This experiment produced disappointing results, and the development of this apparatus was not pursued further because of the elaborate set-up, and lack of clear visual representations of the brain. However, at about
Physics -- History of Ultrasound Physics and Properties of Transducer The history of Ultrasound Physics has involved contributions from many professions from a number of countries over hundreds of years. The first developments, dating as far back as 1794, were made by scientists outside the medical profession and were often disconnected from each other. As science progressed and scientists combined these discoveries, the medical profession gradually realized the value of ultrasound
The student has provided research on various vibration analytic techniques such as the use of Laser Vibrometry for Damage Detection using Lamb Waves in discovery processes to detect microcracks. Outcome 3. The Information Literacy competency was satisfied through the research efforts made by the student through data gathering regarding aircraft structures and vibrations qualification techniques retrieved from the MIL-STD-810F and NASA Langley Research Laboratory. Techniques include Fatigue Damage Spectrum (FDS)
The scanner's ability to translate typewriter characters into bit-mapped image into ASCII text depends on a number of factors, including the sensitivity of the device itself and the legibility and method of preparation of the original document; however, improvements are being made all of the time and even formerly graphic-based scanning systems such as Adobe's notoriously slow PDF applications have incorporated character recognition systems that allow for textual scanning.
Hashimoto Thyroiditis ACRONYMS TSH Thyroid Stimulating Hormone T3 Triiodothyronine T4 Thyroxine Hashimoto Thyroiditis The condition, Hashimoto's Thyroiditis, is named after Hakaru Hashimoto, a Japanese scientist, who uncovered the disease in the year 1912. Amino, DeGroot, and Akamizu (2013) write that Hashimoto explained the conditions of four types of individuals having a chronic thyroid disorder, that he labeled as "struma lymphomatosa." These individuals' thyroid glands had diffused lymphocytic infiltration, parenchymal atrophy, fibrosis, and eosinophilic acinar-cell change. Pathological
