Ultrasound Essay

within the tissue. Although there is obvious evidence that ultrasound temperature heats up thetarget tissue, there is a lack of evidence depicting exactly how much the tissue is heated, so themajority of evidence-based science regarding this aspect is qualitative in nature (Haar, 1999). Itis theorized that the positive effects of ultrasound therapy, referring to strictly the thermal effects,result from increased flexibility of tendons, ligaments, and scar tissue. These effects increasejoint movability

joints, blood vessels, and internal organs” (“Medical” par. 1). Therefore, the use of ultrasounds can evaluate these specific parts of the body. X-rays can not evaluate the internal organs of the body. As BBC states, “Compared to x-ray photographs, ultrasound scans: Produce images of soft tissue” (“GCSE” par. 1). It is important that we have ultrasounds to evaluate the internal organs of the body. Ultrasounds also examine pregnant women for nine months. According to the Wikimedia Foundation, “The

Instrumentation techniques are used for screening patients, diagnosis of patient illness and for treatment of patients. Non-ionising radiation is used to describe the part of the electromagnetic spectrum and it does not carry enough energy. MRI MRI stands for magnetic resonance imaging and it is a scanner which uses magnetism to see the position of hydrogen atoms in water molecules inside the body. This will allow it to build up an image of the internal structures. Quality of information is very

ones that work in the hospital, physicians offices, imaging clinics, medical and diagnostic laboratories. Sonographers can be called ultrasound technicians and diagnostic medical sonographers. The field of ultrasound has many different specialties such as cardiac, OB/GYN, ophthalmic, vascular, abdominal, breast, interventional, and etc(how to). Sonographers use ultrasound, high-frequency sound waves to produce images of the body's internal tissue. They use a machine called a sonographic scanner to create

passionate about doing. Due to my past experiences with my health and others around me, I have found a genuine interest in becoming an ultrasound technician also known as a medical sonographer. An ultrasound is an imaging procedure that produces ultra-high frequency sound waves (ultrasound). These sound waves bounce off internal bodily structures (Rugg n.pag.). Ultrasounds are a painless procedure that is performed by a doctor or technician that is specialized with training (Tavolacci 2316). First, the

Sonography employment growth of a whopping 46 percent between 2012 and 2022, which is among the fastest rates on our list of best jobs in 2015.” Diagnostic Sonography is a type of medical imaging that uses high-frequency sound waves, also known as ultrasound, to produce images of organs, tissues, and blood flow. They are many different types of Sonography majors that can interest you. Their is Abdominal Sonography, Breast Sonography, Musculoskeletal Sonography, Neuro-Sonography, Obstetric and Gynecologic

Using low-intensity ultrasound to evaluate foods quality was first employed in 60 years ago; until recently, the full potential of the technique has been realized (Povey and McClements, 1988). Examples of using of such technologies are found in the location of foreign bodies

The density of material 1 id 25 kg ms-3 and the density of material 2 is 18 kg m-3. The speed of sound in material 1 is 1900 ms-1 and in material 2 is 18 kg m-3. The speed of sound in material 1 is 1900 ms-1 and in material 2 it is 700 ms-1. The acoustic impedance of each material Z= pV Acoustic impedance (Z) Density is (p) Acoustic Velocity (V) For

widely used cell disruption technique at laboratory scale. Ultrasound technology has been applied to various fields (Wang et al. 1997). On one hand it is hardly suitable for the industrial purpose, but on the other hand, it requires neither sophisticated devices nor extensive technical training at laboratory (Feliu et al. 1998). Ultrasound, i.e. sound waves of frequency higher than 15-20 kHz, can cause inactivation of cell; besides ultrasound at

Sound is a mechanical wave, propagating through a medium in order for it to travel (Venables 2011a). Ultrasound is defined as high frequency sound waves, above the audible range i.e. >20 kHz (Zidan et al. 2011). These waves are formed using the pulse-echo principle (Venables 2011a). This principle refers to the piezoelectric crystals which are situated in the transducer. When an alternating electrical voltage is applied across the transducer element (Lieu 2010), the element undergoes a series of
