Energy-dispersive X-ray spectroscopy

based on a new class of semiconductor materials, will deliver the best of both worlds, storing data permanently while allowing certain operations to occur up to a thousand times faster than today’s memory devices. So this new approach may be more energy efficient.Their findings provided new insights into the experimental technology of phase-change memory. October- A new study says that human-induced climate change has doubled the area affected by forest fires in the U.S. West over the last 30…

MRI stands for Magnetic Resonance Imaging. Dictionary.com defines it as a noninvasive diagnostic procedure employing an MR scanner to obtain detailed sectional images of the internal structure of the body. From my own prior knowledge, Magnetic Resonance Imaging is a technique that uses a magnetic field and radio waves to create detailed images of the organs and tissues within the human body. The idea for Magnetic Resonance Imaging was initially conceived by Damadian in 1971 after he recognized…

discovered x-rays. X-rays have evolved drastically over the past 120 years and there have been many new discoveries that are used to this day in diagnostic medicine. Some of the different modalities in medical imaging have also been very helpful when studying art and archeology. Both x-rays and CT’s are used to look at art to confirm its authenticity, archeology for the study of mummies, and also archeology to exam the charred scrolls at Herculaneum and pottery. Over the years, x-ray…

An MRI scanner or a magnetic resonance imaging is a common apparatus used within hospitals which uses a scanning technique to show detailed images of the inside of a human body. There are two ways which an MRI scanner takes images of the human body. The two ways are the use of a strong magnetic field and the use of radio waves. There are two ways which MRI scanners work and the first is by hydrogen atoms. How this links within the human body is by the main link of hydrogen protons which are…

Diagnostic testing for the patient with acute appendicitis included magnetic resonance imaging (MRI) and a Karl Storz image of the appendix. An MRI is a non-invasive technique in which the patient is placed in a magnetic field to examine their body anatomy (Pagana & Pagana, 2014). This form of diagnostic testing provides healthcare professionals with imaging on a specific area of the body with the ability to differentiate between blood vessels, necrotic, and healthy tissue (Pagana & Pagana,…

The trauma radiographer should take the important responsible in radiation protection of the patient, member of the trauma team, and the radiographer himself or herself. Member of the trauma team cannot leave the patient in critical situation while imaging procedure are being performed. The unnecessary radiation exposure should be avoid and the trauma radiographer must unsure the team member are protected. In general radiography, common practices should minimal the radiation exposure include…

X-radiations (X-rays) are electromagnetic radiation that is utilised in performing radiographs; radiography is an imaging technique that utilises X-rays to generate a view of the internal anatomy of an individual (National Institute of Biomedical Imaging and Bioengineering 2017). The use of dental X-rays play a fundamental part in every dental clinic in terms of assisting dental professionals in diagnosing a condition, aiding in highlighting and providing early intervention for various dental…

only take X-rays of bones. Actually radiographic images are taken of every part of the human body, including the abdominal structures, lungs,…

Humans may experience daily exposure to genotoxic chemicals. Exposure to these genotoxic chemicals is often inevitable because they can be found in any environment, from an individual’s home to his or her workplace. The exposure to genotoxic chemicals can eventually lead to high levels of DNA damage, which has been suspected of causing cancer. The DNA damage caused by these chemicals can be measured by sister chromatid exchange. Sister chromatid exchange is a sensitive biomarker that is used to…

utilized as part of a multimodality plan geared towards total obliteration of the malformation. Radiosurgey was first figured out by Cushing and Bailey for AVM patients. The principles of stereototactic radiosurgery are based upon delivering high-energy radiation to a well-defined volume containing the nidus of the malformation. Radiosurgery was first performed with a device called the gamma knife [77]. With proper dosimetry the immediate side-effects of radiosurgery have been moderate and…
