Radiography

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…

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…

Mammograms According to the national cancer institute, a mammogram is an x-ray vision of the human breast. The x-ray vision is used for screening purposes in facilitating the detection of tumors in the breast as well as microcalcifications such as calcium deposits that are critical in the detection of breast cancer. Mammograms used for diagnostic purposes in cases where the patient exhibits symptoms of cancer, and a tumor already detected in the breast. The diagnostic mammogram requires more…

MRI and CT scans are important in the medical field because they distinguish between healthy and unhealthy tissue in the human body. Doctors use these tests so they can see through a picture what is wrong with a patient. Even though both tests are important and helpful, they have their pros and cons. Many people may think that MRI’s and CT’s are similar because they both provide images on the inside of the human body. These two machines work differently and are used differently. MRI scans are…
