There are many names used to describe the ultrasound, including sonogram, diagnostic sonata, or ultrasound (Leonard 89). The medical sophography (ultrasonic image) is an ultrasonic image processing method used for diagnostic medical purposes, which are used in rendering small and thin bodies of the body, such as muscles, tendons and many internal organs for capturing their size, structure and any pathological damage using tomography images (Chaudhuri 317). The Sonogram uses high frequency sound waves to form images of certain parts of the body of a person, including stomach, liver, heart, tendon, muscle tissue, and other things (Veezy 379). This method uses sound waves as opposed to radiation, so it is considered safer because it does not damage the body (Hoskins 8). The ultrasound can be used to detect any problems in body parts that are checked. The technology in this case is usually less costly and mobile, in particular compared to other methods such as MRI and CT (magnetic resonance imaging and computed tomography) (Alter 56). Thus, this is the most popular diagnostic tool in the world of modern medicine
The history of ultrasonic dates back to 19
Over the past decades, many experiments have been conducted in the army to assess the potential of scientific and industrial ultrasound technology. Despite all these developments up to the 1940s, the use of ultrasound as a diagnostic medical tool has become impossible. This happened when the neurologist and psychiatrist Carl Ducik of the University of Vienna developed the concept of ultrasound. During this period, working with his brother, the scientist used an ultrasound beam to look for brain tumors, and also found stomach acids, and cavities in the brain that contained the spinal fluid
Other pioneers from America and Europe have also developed over time and expanded the coverage of the diagnostic medical ultrasound over the next five decades (Mamou 19-24). Moreover, using it to detect a wide range of medical conditions, they have also made great strides as equipment and image quality. In the 1950s, Jan Donald, working in Glasgow, was the first person to use an ultrasound to monitor the development of the fetus (Rantanen 1) during the same period, he also published in 1958 a seminal diagnostic study in which he worked with a group of researchers to create a prototype ultrasound machine designed specifically for medical diagnosis. Over time, manufacturers could take advantage of technological opportunities to develop smaller and portable ultrasound computers
Development, which has led to clearer, clearer and more high-quality images in the future. Further developments and innovations ultimately led to the invention of two, three and four-dimensional ultrasonic ultrasounds in addition to the image. This latest invention has helped the gates of medical specialists, and even patients are better informed about ultrasound tests. By 1970, health workers had already accepted the sonogram as a special and special occupation, and in 1973 the United States Department of Education had even recognized the field as a profession with its own rights. As this period, sonogram, as a field and profession, has grown considerably and has reached its current state in the medical field
Medical sonography is used in various medical studies, which include anesthesiology in which ultrasound technologies are administered by anesthesiologists when injections are used to administer local aesthetic solutions close to the patient’s ner. At the same time, this technology is used in echocardiography to detect any vacuum on the heart path, as well as to verify the correctness of the heart and valve function. In addition, it is used in emergency medical and emergency departments to speed up the care of patients who may experience gals or experience severe pain in the upper abdomen. Ultrasound technologies are also widely used to manage pregnancy, defining important things such as the heart of the child, the expected delivery time and the location of the fetus. In fact, this technology can be used to indicate the sex of a child during pregnancy (Bruno 325). The Sonogram is used and applied in many health facilities, including Neonatology, Neurology, Otolaryngology and gastroenterology
Ultrasonic impulses transmitting high frequency sound pulses (echoes) into the patient’s body and sound waves, in turn, are transmitted over the body into different tissues at an average speed of 1540 m/s, even if this speed differs depending on the type of tissue. The velocity of the ultrasound through the fat is 1459 m/s and in the bones-4080 m/s. As the sound passes through the fabric with various acoustic properties, there is a proportional power of sound (Hoskins 8). The boundaries between the two different tissues are known as the acoustic interfaces, and the number of sounds reflected in the acoustic interface is determined by the type or properties of the materials on the sides of the interface
Echocardiogram is usually an abbreviation (ECG)-an ultrasound that runs in the heart that uses the echo process. In modern society it is used in many cases in diagnosis, management, and also
As explained, the echocardiogram is a non-invasive ultrasound examination of heart and large vessels, which differ substantially from the ordinary ultrasound, because of its ability to provide relevant information about human anatomy, hemodynamics, functions of dynamic systolic and diastolic heart, as well as for large vessels. It is important to note that the echocardiogram can be either performed as a basic comprehensive assessment or even under controlled stress conditions to carry out a functional assessment of the significance of the vascular erosion. There are different kinds of echocardiograms that can be used in the creation of heart images, and they include an echo, which is said to be the most common type of echocardiogram (St 203)
This assumes that a special device is transmitted on the chest to the syneologist, which then transmits the special sound waves through the wall of the thorax to the heart, resulting in the waves turning back to the computer and automatically converted to images. Stress-cardiography is usually carried out as part of a test, where you can run or take some medicine to make it faster, after which the technician will take echoes from the heart just before the exercise or with the medicine, and immediately after the medicine has been performed. This type of echocardiography can help diagnose certain problems, such as coronary heart disease
The transsexual Echocardiography is a method in which the converter attached to the end of the flexible hose is directed downwards in the oesophagus, allowing the sonologue to obtain a more detailed picture of the heart. Fetal echocardiography, on the other hand, is used to test the heart of the unborn child and is recommended for the 18-22 week of pregnancy. Finally, in three dimensions, echocardiography helps to create three-dimensional images of the heart, as it takes an echo and is used to diagnose various problems with the heart of the children, as well as the planning and monitoring of heart valve surgery
Pain may be caused by various problems which may differ from coronary artery disease, aortic artery, embolism and stomach embolism, reflux esophagus among other factors which include pain in muscle pain, insanity, pleural papers, psychosomatic, psychosomatic and pericardioids. In such cases, many doctors should exclude coronary heart diseases and aortic disks, as they are curable and show most of the symptoms. A careful echo is usually carried out to detect and diagnose the acute syndrome or any other possible infection that can be found in the patient. If the ECG shows that there is any anomaly and rotting around regional movements, it is assumed that the old myocardial infarction is otherwise
Many manufacturers recently started producing harmonics on echocardiography computers. The reason for this visualization is that reflected sound waves can contain second-degree harmonics that have wavelength form, but have a sexual life or half wavelength, so the harmonic system of image creation helps the system emit energy, which is usually lower. The harmonic image also helps to maintain normal frequencies, and this does not affect the quality of the image. However, care must be taken when the application is running, because continuous loading can lead to unusual text in the image
The contrast is another new application that is used in the demonstration of noisy saline injections (Walsh 198). Contrast agents are created on a commercial basis and consist of bubbles that are free and hermetically sealed. In a tiny air bubble, reverse scrolling has been improved to help isolate the fabric that contains the contrast agent. This method is used in various applications, including the filling of the cavity when the blood is rendered in the left ventricle, since the boundaries between the blood and the myocardial stand out. The contrast is also used in the myocardial perfusion, where it is injected by injection, and helps to regulate the changes associated with the increase in the workload, as well as to delimit the myocardium that is supplied by each coronary artery
The contrast is also used to increase the flow of the heart, so that it is introduced in order to increase the number of reflectors and thus increases the intensity of the resulting spectral trace. This is also important in the case studies of dropper. The multivariate echocardiography is used mainly with transosophage and intranecular ultrasound, and it helps in providing real time of processing of the heart structure as well as its functioning. Because it is non-invasive, it is more effective in describing and communicating anomalies with specialists, and can also help to better determine the position of structural defects of the heart in a connection to each other and other heart structures. Thus, this method provides precise descriptions that can be used even for surgical repairs
Echocardiography is recommended for initial diagnosis with a noticeable change in the patient’s clinical condition and, as such, should not be used unless there is a noticeable deterioration in the patient’s condition based on test results. Echocardiogram is important because it helps the doctor easily carry out diagnostics, monitoring and analysis of heart conditions for any abnormal heart rates, heart cancer, infection in the heart, sources of blood clot and lung hypertension among other problems
