X-ray computed tomography

foreign bodies containing metal are strongly attracted to the magnet, and the improper use of the equipment. Magnetic Resonance Imaging (MRI) is a popular machine used to image the human anatomy in multiple cross sectional slices. Unlike Computed Tomography, MRI machines do not use any ionizing radiation to develop these images. However, an extremely strong magnetic field and with radio waves are used instead. While there is no radiation risks associated with MRI, it is important to understand…

Interventional Radiology is a novel field of medicine that combines the expertise of a radiologist together with the knowledge of therapeutic intervention using advanced techniques using a range of imaging guidance modalities such as X-ray fluoroscopy, ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) to accurately treat a medical condition. By the same token, Baum and Baum (2014, p. S76) implies that using the same diagnostic imaging tools that transformed medicine also…

Nuclear medicine is used by physicians all over the world, pre-dating Computed Tomography (CT), Magnetic Resonance Imaging (MRI), and Ultrasound technology. Tests are conducted using pharmaceuticals in conjunction with specific mechanical imaging, allowing optimal diagnosis for various conditions. Nuclear medicine allows doctors to see inside the body in ways that X-ray, CT, and MRI alone cannot, providing the most accurate way to study and diagnose specific abnormalities within the body’s…

Computed tomography (CT) scanning technology was discovered in 1972 and revolutionized the world of neuroimaging (Sadock, Sadock, & Ruiz, 2014). The CT scan was the first technique to allow the imaging of brain tissue in living patients (Sadock, Sadock, & Ruiz, 2014). During a CT scan, a patient lies on a flat surface, which incrementally moves through what is referred to as a gantry (Sadock, Sadock, & Ruiz, 2014). A gantry is a round shaped structure that contains a motorized x-ray source…

The CT scanner Depends upon several steps:- 1-The x-ray tube and detector transverse (scan) the object. 2-The radiation beam passes through the object and is attenuated. The intensity of radiation beam from x- ray tube and transmitted beam both are detected by suitable detectors. 3-The transmitted beam and the references beam are both converted into electric signals. 4-These output current signals are then converted into digital form by analog –to-digital converter. 5-The digital data are…

Medical Aspect of Nuclear Chemistry Nuclear chemistry is a growing subfield of chemistry. Although it has also has been used for the destruction of humanity in history this paper discuss on how it has been helpful through medical aspects. Nuclear chemistry is related with radioactivity, nuclear processes, and properties. In order to build a nuclear process, radioactive elements are combined with nuclear reactors. In order to identify which chemicals should be used for medical purpose,…

A hero can be classified by many things. A hero can be superman, a police officer, and even your mom, but what makes a hero. Is it someone who can fly or shoot laser beams from their eyes or someone who saves a baby from a burning building. I’ll admit some of these characteristics are far-fetched since I don’t know anyone who can fly or randomly saves babies on a normal day. All heroes, including super ones all, have something in common, they're admired for their courage or an outstanding thing…

Nearly all ancient societies practiced body modification through either piercingss or tattoos. These ancient practices are becoming ever more present in our modern Canadian society, especially tattoos. One writer says, “Permanent tattooing is the process of body modification by deposition of a pigment into the dermis” (Simunovic and Shinohara 525). In the past three decades, magnetic resonance imaging (MRI) has become increasingly popular in the medical field. Magnetic resonance imaging is a…

viewing. The development of the electron microscope in the 1930s revolutionized biology, allowing for organelles, such as mitochondria, to be seen in detail for the first time. Unlike light microscopy, TEM uses a beam of electrons, denoted as a cathode ray, to scan samples. While the traditional optical microscope is restricted in resolution by the wavelength of…

Many Americans go through their days not without the knowledge that they are facing commodities that pay its derivation, to some degree, to some NASA project or other astronomical research. This is particularly true when one is thinking about the medical field and a lot of its advancements. Various medical innovations are the result of NASA 's collaborations with other examiners, and others were derived as a result of NASA researchers who recognized significance in findings and mechanics they…
