Applications of Ultrasound in Medicine

Applications of ultrasonography in MedicineAB Assessment Using WavesIntroduction ultrasonography is a sound waver with an oscillating pressure wave with frequencies ranging from 20 kHz until approximately 200 MHz. These frequencies ar non audible to humans. inaudible devices atomic number 18 applyd to detect objects and measure the distance between them. ultrasonography has been more frequently used in checkup imaging displaying the forbearing an object in their organic structure or just generally tone at their form. ultrasound seemingly is becoming commonplace imputable to it not emitting any beam of lights unlike X-Rays. 6Uses of ultrasoundechography is used in the medical department as a means of imaging, enabling medical cater to facial expression the patients body without any major problems. The most common use of sonography in the medical department is its use in what is called an ultrasonography scan. This is used to project a moving image of a fetus insi de a pregnant womans body. An example of this can be seen on the left. ultrasound is not only used to detect unborn fetuses and also view several organs in the body through prenatal scanning The same system used for an ultrasonography scan. Since echography easily reflect off soft tissue, gel ask to be added to the part of the body where the scan is going to be conducted. A transducer is so used to generate the ultrasound waves and detect any echoes it receives from the reflected waves. During the dish up of scanning the waves also erode pieces of gallstone which reside within our organs, with their eonian vibrations.6712Another use of ultrasonography is echo sounding. This is used by the tonus control industry to detect flaws in pieces of metallic element. As an ultrasound wave is being passed through the metal, it ordain r apiece the defect area in the metal and the reflected wave that came of the defect area will be standard by the transducer that emitted the wave. If in that respect is more than one reflected wave it means the metal is defect. 7121315Ultrasound waves can be used by the industry for cleaning.12 The waves are sent through a fluid and bubbles formed from the vibration of the ultrasound remove dirt from an object. The object which is placed in water or another solvent has fluid collapse into the gap left commode from the solvent. The bubbles then move rapidly, removing the dirt and resulting in a transcending standard of cleanliness.1215Dangers and RisksThe dangers of Ultrasound are considerably low compared to other waves. Even though there is no major threat in using ultrasound it does accommodate its risks which could harm the user.Excessive exposure to ultrasound waves of 120dB can hold in to earshot loss. 6Excessive exposure of ultrasound waves at 155dB will commence cavitation high temperature up the users body cells. 6Excessive exposure to ultrasound waves of 180dB may lead to death. 6Cavitation may cause the users cell s to heat up and invoke toxic reactions. 23 counterchange in cells may cause Intestinal bleeding. 23Damage to fetuss brain may lead to left handedness. 23Prenatal scans may cause early labour, premature birth, miscarriage and perinatal deaths. 23Possible disabilities formed are epilepsy, dyslexia and delayed speech development. 23Ultrasound in physiotherapyThe aim of physiotherapy is to help restore movement and normal body function in cases of illness, injury and disability.. 1 Physiotherapy tries to cure dis adaptedd body functions from affected people. Ultrasound has found its way into this world, bringing its useful treatment methods with it. Its used to treat deep tissue injuries, reduce pain from spasms as wells as inflammation and swellings, increase tissue extensibility, speed up metabolism, reduce nerve irritation, enhance drug delivery and speed up healing. Ultrasound stimulates the blood circulation and the activity of cells to assist in the therapeutics. 1 3 The ultras ound frequency that is used for physiotherapy ranges between 0.7 and 3 MHz. 5 Gel is applied to the patients body to reduce friction with the transducer and aid the transmission of ultrasound waves. The waves are absorbed by ligaments, tendons and fascia and the therapeutics affect apply. 5Advantages and Disadvantages fixsSocial come toHospitalized childbirth has gained a sudden rise since the 20th century. This is due to the improved hospital engineering science and successful childbirth probability. 16 Since ultrasound has been part of the hospitals technology, mothers have wanted to view a fetal scanning of their unborn child. This has been done multiple times, but society keeps questioning if ultrasound scanning is safe. The fact of being able to view your unborn child provides ultrasound a plus head up to its beneficial use. It allowed parents to find out the gender of their child onwards delivery and detect any abnormalities that may occur during pregnancy. 16Moral Impact The use of ultrasound in prenatal scanning seems to be that it affects the family between mother and fetus. The cultural conversation is gone and what remains is communication through a computer screen displaying the fetus. The mother will then use what she sees instead of relying on her embodied knowledge. 17 Ultrasound brings imbalance to the object lesson standing of the victim through injurious damage to the victim. This raises the moral ken of fetuses and if they should be exposed to the waves emitted, which can bring injurious damage. But this will then degrade the mothers moral standing as she also becomes a victim of the injurious damage ultrasound can bring. 17Ethical ImpactUltrasound has been most commonly known for determining the gender of the fetus. Ultrasound is a cheap resource since all you need is a transducer and soulfulness who can operate the device. In countries like China and India, parents exploit this method by checking the gender of their child and then deciding to abort it due to the countries preference of males. 18 In india there are 250,000 female feticide abortions each year. The government has been trying to motivate people into valuing female fetuses but the economical and Social impacts have lead to the occurrence of this honourable issue. 18ConclusionUltrasound is a secure soundwave with a minor probability of great risks. Ultrasound has been proven to be beneficial and useful in most industries and is popular in the medical industry. Its a method used in physiotherapy to speed up healing and to improve the overall therapeutics. Although it has tell advantages and disadvantages, and is not worth recommending it should not discourage anyone from using ultrasound waves.Bibliography1 Physiotherapy How It track downs .
