X-ray Essays

Diagnostic imaging techniques such as MRI and X-ray scans are both use in medical/clinical settings to help doctors with their diagnosis of a patient 's body. By using these techniques, a more accurate diagnosis of a potential or present injury/ illness of a person can be understood and can be visually determined. With that being said one major difference in the way that the two techniques obtain their images is the use of radiation. In an X-ray scan the use of gamma radiation helps with being

tomography, uses X-Rays from many different angels to make a detailed picture of the structures inside the body. It allows doctors to see what is happening inside the body without having to cut somebody open. A CT scan is taken in a donut shaped ring and a bed, the bed gets rolled into the scanner. An MRI, standing for magnetic resonance imagining, use strong magnetic fields to make photos of the organs in a person's body without cutting the body open. An MRI machine does not use X-rays to make photos

was first discovered in the early 19th century. William Herschel discovered infrared radiation, and Johann Wilhelm Ritter discovered ultraviolet. Heinrich Hertz first produced radio waves based on Maxwell’s theories, and Wilhelm Röntgen discovered X-rays. In present time, electromagnetic radiation is important. It is commonly used in telecommunications, household appliances and also medical equipment. Even though electromagnetic radiation has its risks, technology is

diseases seen within the body. Radiologists use many imaging techniques including: X-ray radiography, ultrasound, computed tomography, nuclear medicine including positron emission tomography, and magnetic resonance imaging to diagnose and treat diseases." Some of the experiments they do include testing X-ray dark-field radiography on a living organism for the first time. They test the organism for lung disease. X-Ray dark-field radiography produces very detailed imagines of the lung. They hope to be

professionals to look inside a person’s body through the development of detailed pictures or scans. Computed Tomography (CT) technology is one such modality that takes detailed cross-sectional images using computer controlled X-ray technology (Davis, 2016). Other modalities include standard X-ray and Magnetic Resonance Imaging both of which can also create pictures of inside the body. Since these modalities all serve similar functions, why would doctors need to choose from more than one method to diagnose

n this essay I will be talking about X-rays.I will also talk about how pneumonia is able to be treated by X-rays. X-rays are a kind of radiation called electromagnetic waves. X-ray imaging forms images of the inside of a human body. The picture will show the part of your body in various shades of black and white. This is a result of various tissues taking in various amounts of radiation. Calcium in bones take in X-rays the most, so bones look white. Fat and other soft tissues take in less, and look

There are different types of image modalities in healthcare such as a CAT Scan, MRI, X-Ray and ultrasound imaging modalities. A CAT Scan is an X-ray image made using computerized axial tomography. Magnetic resonance imaging, more known as MRI is a medical imaging technique that is used in radiology to form pictures of the anatomy and the physiological processes of the body in both health and disease. An X-Ray is a photographic or digital image of the internal parts of something, especially a part

achieved, assessment of image quality must be made to balance against patient dose. X-rays are known to cause malignancies, skin damage and other side effects and therefore are potentially dangerous. It is therefore essential and mandatory to reduce the radiation dose to patients in diagnostic radiology to the barest minimum (Watkinson, Moore’s., 1984). Radiographers are technologist who create and analyze the x-ray image. Diagnostic radiography plays an important part in the treatment of neonates

Photoelectric interaction is one of the main interactions in producing x-rays. This occurs when an inner shell electron is knocked out leaving a hole that needs to be filled. It will be filled by an outer shell electron which will be filled by an auger electron eventually. Photoelectric interaction doesn’t have as much scatter compared to the other interactions. This is due to the photons being almost completely absorbed by the patient as the photons pass through the body to hit the image receptor

Ultrasound can be used as an alternative to x-ray for many investigations to minimize the use of radiation. The utility of ultrasound in the NICU lies in its portability, reliability and lack of radiation exposure. In NICU, ultrasound can be used for a wide range of indications, such as research, proceed guidance and rapid assessment of critical emergencies. In addition, ultrasound can be a guidance to improve safety and success rate of clinical procedures, such as umbilical vein catheter (UVC)

The inventor of radiology was scientist, Wilhelm Conrad Roentgen, and the first ever x-ray was actually of his wife's left hand on December 22, 1895. This machinery took off and is used all over the world by a Radiologic Technologist. A Radiologic technologist performs all types of medical imaging procedures, but most commonly x-rays. Radiologic technologists are also known as radiographers or x-ray techs. They provide a high standard of patient care, prepare patients for examinations, and explain

Anything that can be used in a court of law is referred to as forensics. Forensics can be any scientific test that can prove a connection to a crime. The information obtained in any test must be admissible in a court of law. There are many branches of forensic sciences; one branch that is not well known is forensic radiography, or forensic imaging. “Conducting examinations that use ionizing radiation to gather and analyze forensic evidence constitutes forensic radiography” (ASRT. (2010).). Radiography

benefits of a CT scan far exceed the risks. CT scans can provide detailed information to diagnose, plan treatment for, and evaluate many conditions in adults and children. Computed Tomography imaging also known as CT or a CAT scan, combines a series of x-ray images taken for different angles and uses computer processing to create cross- sectional images also known as slices of the bones, blood vessels, and soft

(Computed tomography) and conventional radiography. The most important advantage of MRI compared to other imaging modalities is the fact it uses strong magnetic field strengths for imaging unlike other modalities which use ionizing radiation like x-rays for imaging. The principle of MRI lies in using strong magnetic fields to excite certain atoms within the body and then using radiofrequency

radiation carries energy to ionize atoms and has more energy than non-ionising. Non-ionising is found at the end of a long wavelength where as ionising radiation is found at shorter wavelength. Regions of the spectrum: • Gamma radiation- ionizing • X-ray radiation- ionizing • Ultraviolet radiation- non-ionizing • Infrared radiation- non-ionizing • Microwave radiation- non-ionizing • Radio waves- non-ionizing 3- A) Lethal Dose Effects 5-20 Possible late effects; possible chromosomal damage 20-100

The radioactive agent commonly used to radiolabel the white blood cell include 99mTc -HMPAO and 111In-oxine. Technetium-99m is used in the blood or injected into patients systemic circulation so that it can be detected by medical equipment such as X-ray. Technetium exametazime under brand name of Ceretec which commonly perform radiolabel

the demand of diagnostic imaging to aid diagnosis. In the authors experience, there appears to be a patient preference towards MRI as it does not use ionising radiation to obtain its images, therefore, in the public eye it is much safer than CT and X-ray. At this moment in time there are no known biological effects to those who come in contact with the static magnetic field. Little do the public and many healthcare workers know the injuries that can occur if MRI safety is not adhered to. Due to previous

Discussion The ankle is the most frequently injured major joint in the body. Ultrasonography (US) performed with high-resolution broadband linear-array probes has become increasingly important in the assessment of ligaments around the ankle because it is low cost, fast, readily available, and free of ionizing radiation. US can provide a detailed depiction of normal anatomic structures and is effective for evaluating ligament integrity. In addition, US allows the performance of dynamic maneuvers
