Advantages And Disadvantages Of Using Ultrasound Over Conventional Methods

During a pregnancy, many expecting mothers will travel to the doctor to have a check up with how the pregnancy is doing. Many mothers will get done a special procedure that is called an ultrasound. An ultrasound is a procedure that uses high-frequency sound waves to scan a woman’s abdomen and pelvic cavity, creating a picture (sonogram) of the baby and the placenta.(2-1) Ultrasounds may be performed at any point during a pregnancy, and the results are seen immediately on a monitor during the procedure.(2-2) The ultrasound doesn’t hurt the mother or the fetus. There are many situations where ultrasounds can be used. Some doctors will use an ultrasound to look at someone’s abdomen, especially if there is stomach pains and nausea present. One

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.

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.

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

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.

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:

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.

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 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

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-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.

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,

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
