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…

Introduction An MRI (or Magnetic Resonance Imaging) scan is a radiology technique that uses a large magnet, radio waves, and a computer to look at organs and structures inside our bodies. Single MRI images are called slices can be stored on a computer or printed on film. An MRI combines images to create a 3-D picture of your internal structures. The MRI scanner is a tube surrounded by a huge circular magnet. The patient is placed on a moveable bed that is inserted into the magnet. An MRI…

Thermal MR Injuries “The number of MR imaging related adverse events has increased steadily since the first years of clinical use, which may be due to the increase in the number of MR procedures” (Hardy& Weil, 2010). The primary type of adverse injuries is skin injuries. The Joint Commission and other organizations have raised awareness of skin injuries that are related to MR imaging. Technologists should always pay close attention to prevent accidents and injuries during MRI procedures.…

aligns all the Hydrogen protons in the body into one direction or plane i.e. to polarise the spin into one direction since all the atoms precess about their own axis. Once all the Hydrogen atoms are aligned along the same axis the Varying Coils labelled X, Y and Magnetic Z Coils in Figure 2 apply a second magnetic field of similar magnitude to the uniform field at a specific target location that is being investigated. The purpose of this is that it will flip the spins of a specific number of…

The position of the source is crucial for accurate treatment planning and delivery. The patient needs to be examined (through ultrasound, CT imaging, etc.) before treatment planning begins and before each treatment so that the geometry and positioning of the source to the intended target is precise and accurate. Each day before HDR treatment, the radiation therapist must utilize a departmental QA checklist. There are several components to this checklist. • Visual inspection of transfer…

What is a X-Ray Technician A X-ray Technician is a person that uses technology to check how well a person's body is doing and to check if the body is damaged. According to the Mulcahy(1971), “On November 8,1895 a scientists named Wilhelm Roentgen discovered the most useful medical technologies we use today X-Ray(pg.73).” X-Ray machines are described as cutting-edge imaging method to visualize the inside of the human body.According to Mulcahy(1971) X-Ray help diagnose and treat illnesses or…

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…

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…
