Radiography

PLANMECA One of many duties a dental assistant is responsible for is to take radiographs for patients before the dental appointment or during if the doctor request them. These radiographs are used so the doctor can diagnose if there is any cavities, diseases ECT. As well dental hygienist use those radiographs to identify calculus and periodontal diseases. Radiographs take a big role in dentistry. As a student graduating as a dental assistant I have notice and experienced with patients that…

Computed Tomography A CT scan is produced using plenty of x-ray images from lots of different angles using computerized axial tomography (cat). It produces cross-sectional images or slices of bones, tissues and the angio portion which is produced through a CTA (cat scan angio) allows professionals to view the blood vessels. It is a great medical tool, with interesting history and of course like everything else in the worldwide medicine, it has its pros and cons. A Computed Tomography scan is a…

X-rays is one type of electromagnetic radiation that can send waves through the body which makes us see through the body tissue but it doesn’t go through the bone. Therefore it is used in hospitals to see if a person has a broken bone or any diseases. Because it can go through clothes and the human skin it is also used in airports to see if anybody has a knife or anything dangerous with them. X-rays were first discovered by German scientist Wilhelm Conrad Roentgen in 1985. Roentgen found x-rays…

In the late summer of 2015, I needed a career change and wanted to do something that would be rewarding, meaningful, and challenging. In November 2015, I was invited for a trial and interview in the clinical imaging department at West Middlesex Hospital for an assistant administration role. I did not get the position, but I learned a lot from it as I worked a day filing the pending forms into the RMS system. I found it interesting that each scan had a different code. It was also good to find…

The American Registry of Radiologic Technologists, founded in 1922 is the world's largest authorization association that specializes in certifying technologists. The organization focuses on certifying and registering people in the work force. This association is important because it's required to be registered in order to be able to work in the desired field. The technologists are certified with various extensive tests and exams. In addition to the job opportunities one can get by becoming…

How exactly do medical imaging and geometry relate to each other, you may ask. They are certainly different things, but maybe not as different as people might believe. The property that connects these two subjects is 3D reconstruction, which plays a major role in the geometry aspect of medical imaging. First of all, I should explain specifically what 3D reconstruction is: the use of numerical approximation to rebuild 2D images by a computer taking the 2D data slices, reading the data, and…

eliminate patient’s pain. My knowledge and experience about the importance of diagnosis convinced me of the importance of radiography and cemented my ambition to become a Diagnostic Radiography. My biggest ultimate goal is to become a Superintendent Radiographer, working with Hospitals to help train the future generation of radiographers. I want to study Diagnostic Radiography to learn the requisite knowledge and practical experience to achieve my goal and help diagnosed diseases before it…

Mammograms, ultrasounds, x-rays, and MRIs have helped women with breast cancer since 1895 (x-ray) 1956 (ultrasound) 1977 (MRI), and 1992 (mammogram). They have all been very beneficial to women. Breast cancer is the most common type of cancer in women. About one of three cancers are diagnosed. Cancer is a group of diseases that cause cells in the body to change and grow out of control. Most cancers will form a lump or mass in the breast, which is called a tumor. It is named after a part of the…

I travel the St. Louis-Boston air route on an almost weekly basis. At times Boston Transportation Security Administration (TSA) stops me. Every time I am being stopped, I end up exhausted, confused and even a bit shaky. As I get prepared to cross the TSA security checkpoint the rush starts. I tend to feel somehow naked. A sensation I believe might be shared with those who actually did strip naked to show TSA screeners that they were not carrying a bomb, as John Brennan did in 2012. Once all…

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…
