Catherine Mill argues that obstetric ultrasound has some impacts upon the embodied experience of pregnancy. For her, Ultrasound does not simply represent an already existing body, but actually constitutes the foetus as an embodied, social being. The basic question whether abortion is morally right or wrong enters into another domain through an analysis of biopolitics of reproduction. The routine use of ultrasound in obstetrics has its impact on the intuitions about the moral status of the foetus. ultrasound plays a significant role in the circulation and realization of norms in reproduction by establishing and shaping embodiment and thereby constitute social and ethical relationships. Ultrasound imaging allows the bodily life of the foetus
Moving larger within basketball's game is one thing that many players execute on consistently. It only would seem sensible when-you're trying to score on the ten-foot holder the better the more odds can bounce you have of getting a larger participant and carrying out more concerns around the courtroom.
Pregnancy is a very exciting time. The photos, the food, and the announcements are enough to make anyone squeal with joy. One of the most exciting times during your pregnancy is learning the gender of your baby. An ultrasound during your second trimester can reveal whether you are having a boy or girl, which will allow you to continue shopping and planning. If you are going in to have an ultrasound soon to determine the gender of your baby, use these four tips to help the ultrasound technician get a good view of your baby:
ABSTRACT: This paper will demonstrate how ultrasound has been a key tool in aiding the Center for Disease Control (CDC) in diagnosing how the outbreak of Zika virus has led pregnant women to develop fetal abnormalities such as microcephaly among others. An ultrasound is used to determine microcephaly by measuring the fetal head circumference (HC). If the HC is more than 2 standard deviations (SD) below the mean compared to other fetuses that same age and gender then this indicates microcephaly. A condition such as microcephaly usually doesn’t present itself until the second or third trimester. It is important for the sonographer to be proficient and to have time on their side in hopes for an early detection, thus recommending regular ultrasounds every few weeks to monitor the progress of the fetus.
Although ultrasound QA guidelines exist for over 35 years, the implementation of QA has been inconsistent.25 One of the reasons for that may be a general opinion that formal QA in ultrasound is unnecessary because it is based on non-ionizing radiation. For imaging modalities where ionizing radiation is used, as mammography, QA is obligatory. The other reasons could be the lack of medical physicists and medical physics departments in hospitals and sonographers workload which limits the access to equipment. Although there are no legislation
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.
Although ultrasound and infrasound are both the study and use of sound waves, they are used for very different applications. Ultrasound is used with its’ reflection off barriers to provide pictures based on the time that the reflection needs to return to its’ original source. Infrasound, provides information by the directional change of its’ waves.
Ultrasound and MRI are devices which are used in medicine. These devices are used to provide patients with a correct diagnosis and treatment. An ultrasound sends sound waves into the body and listens for the sound waves that are bounced back. Whereas, an MRI uses magnetic fields to line up the molecules inside our bodies. The MRI machine is huge and expensive whereas, an ultrasound machine is small and cheap. An ultrasound scanner cannot view through a bone in the body whereas, an MRI can view through the bone. In an MRI, the patient has to remain very still until the procedure ends, while for an ultrasound the radiographer can see what is happening inside the patient, for example, what the tissues do under stress. Ultrasound scanning produce
We have been practicing veterinary medicine since 1900 BCE but have made more progress in the last hundred years because of modern technology. Without modern technology, more and more animals would die each year. Two major tools that have made practicing vet science less dangerous are ultrasounds and laparoscopic procedures.
Ultrasound therapy generates high frequency waves that deliver vibrations into tissues. A special ultrasound gel is positioned on the skin to amplify contact, preventing to overheat, and providing the wand to glide through skin smoothly. The ultrasound therapy treatment wand is traveled throughout the surface of the skin. The wand transmits energy for three to five minutes around the zone of injury. The therapy can be treated twice daily depending if the patient has been diagnosed with acute pain or chronic pain.
Many factors have contributed to the dramatic increase in the clinical applications of medical diagnostic ultrasound: better understanding of the design criteria for transducers; the miniaturization of electronics; the formation of computer-based signal processing; the creation of flexible microprocessor-driven instrumentation; a lacks of demonstrated adverse biologic effects (Hedrick et. al,
Piezoelectric effect was discovered by Currie brothers in 1880. Further, in 1927, Loomis, wood studied the ultrasound therapeutic ability. In 1940, Ludwig and Struthers published first research paper on ultrasound. It was the first pulse-echo mode ultrasound for the detection of gallstones in animal tissues. Howry and Bliss, in 1950 were succeeded in analyzing and depicting the anatomic details of an organ in water bath using B-mode technology. Ultrasound (US) is most widely used diagnostic modality which is cheap as compared to other imaging modalities. Some of its advantages include non-ionizing radiations, real-time data availability, large & scalable imaging depth, portability and cost effectiveness. A highly advanced ultrasound came to a stagnant phase when its hardware was improved along-with its software and algorithms. So, the only place to expand the scope was imaging at cellular and molecular scale. Additionally, providing diagnostic information beyond that of conventional sonography, and usage of contrast agents. To address the cellular and molecular scale, the idea was to spatially localize the contrast between diseased and the health tissue. It is realized that
Ultrasound is nontoxic, noninvasive and does not use ionizing radiation. The ultrasound equipment has the potential to increase efficacy and early detection in diverse medical fields such as anesthesia delivery, cardiac surgery, sports medicine, and emergency medicine. An ultrasound is uniquely powerful in that it is the only imaging technology that can be transported to a patient or used where a patient might most urgently need it. The ultrasound can be utilized on the side of a road after a serious motor accident or in remote communities, as well as, traveling to reach a health center. When considered this massive scope of medical applications, along with the universal necessity for imaging equipment among the country and borough population in India. The evidence shows why India 's ultrasound market poses both a significant business and public health opportunity.
Ultrasound-based approached can facilitate drug and gene delivery by increasing the transport of therapeutic agents across the cell membrane and endothelial barrier. The function of ultrasound is that it can induce cavitation, which is a process of nucleation, growth, and oscillation for gaseous cavities. The cavitation can cause strong physical-chemical and biological effects in tissues1. Subsequently, the collapse of cavitation bubbles will disruptive the membrane of cells and tissues to enhance drug transport.
The main principle of ultra sound imaging system is to transmit ultra sound burst signals into the particular organ and produced echo is processed for imaging.
