X-rays: What are they and what can they be used for? Within the medical field, doctors and physician assistants use x-rays to help with their diagnoses. X-rays can be used for many practical purposes both in the medical and industrial industry. They both use x-rays to see within something to get a better understanding of what is going on inside. While both modalities use them in relatively the same way, they have key differences in what they need to accomplish. While the industrial industry uses them for more of keeping their equipment maintained, the medical field uses them for diagnoses and proper treatment. It is true that x-rays, when used improperly, can be harmful to people. However, when used properly by a trained technician, they can …show more content…
CT, also known as computed tomography, has many uses in the medical field today. The CT machine looks like a 7-foot doughnut; it has a center circle that has the width of about 4 feet, which is called the gantry. The CT machine uses x-rays and a receiver to collect the images taken. The CT machine can take multiple 1mm to 10mm slices per rotation. This machine is very useful for getting 3D images of the human body. The CT machine can see, with detail, into the human body so radiologists can diagnose different diseases. Unlike regular x-rays, the CT machine can get very detailed images of different types of body parts, inner organs, and artery and veins all within a single scan (Imaginis, 2017). The CT shoots multiple x-rays through the patient while the spinning around the patient. While in rotation, the CT machine collects the x-rays on the other side of the patient to make a 2D image slice of the part scanned. Once the scan of the patient is done, the images are then stitched together by the technologist to make a super detailed image of the body or body parts scanned. The technologist can then form a 3D image of the bones, organs, veins, and arteries within the …show more content…

Courtney Meade Case Study In The Medical Field

...Courtney Meade is an x-ray technologist at Tennova North Hospital in Knoxville, TN. I asked her a series of question on November 20, 2015.Courtney is credential to work in AART (B), CNMT, x-ray, CT scans, and nuclear medicine She always knew she wanted to be in the medical field but wasn’t exactly sure what degree she would to pursue. It wasn’t until Courtney was in a car accident when she was sixteen years old that she knew she wanted to pursue a career in x-ray technology. This decision could be made, because it is really amazing to see what x-rays actually look like, to learn what they are, and how they work. Sometimes it’s hard for even college students to figure out what they want to major in, to hear her say she knew at sixteen what...

The technology in the area of physical science makes it very important on how much is learned and studied in the fields of astronomy, chemistry, physics and even earth sciences. There have been many advances that allow for direct measurements in the field of physics, there are many obstacles and challenges to making direct observations in many circumstances. Physics is the study of energy, matter and the interaction between the two, which are impossible to observe with the naked eye. One common thing the field studies is energy creation to non-particles, all of the most recent discoveries in subatomic particles and the origins of the universe have all creative methods to study things that are extremely tiny. This would be the first major challenge to making direct measurements in physics. To avoid this problem, physicist usually studies these particles indirectly through things like associated radiation, energy, or the displacement of other atoms and/or compounds. Every measurement made on atoms or subatomic particles has caused indirect measurements (Kross). There are certain measurement tools whose invention has been very important through a large range of scientific fields. One example of this is the microscope. The microscope uses electrons to develop high resolution images of small objects...

... Ethical Issues in Radiology Interview Paper Annelia Cyril Adventist University of Health Sciences 2 Abstract As a health care professionals we live through our career with sincere dedication to our patients. Ethics encompasses a variety of issues that all medical professionals, including medical imaging technologists must ultimately tackle. When considering ethics, medical imaging professionals need to take into account their responsibilities to patients, colleagues, employers, the imaging profession, and themselves. This interview will review these responsibilities with respect to medical imaging and the challenges that imaging technologists may face in approaching their work from the perspective of ethics. The American Registry of Radiologic Technologists (ARRT) has developed a Standard of Ethics in which radiologic technologists have to abide by. With the continual invention and improvement of lifesaving medical technology also comes the burden of ethical decision making. Radiologists today face more ethical issues than meet the eye. ...

...microscopes, it would have been impossible to comprehend the composition of the most basic cells. The exact issues are the current issues in the field of physical science today, but it’s particularly true in the world of physics. While new technologies exist to measure phenomenon, it is not always safe to do so in the field that deals with radiation, unstable compounds, particles and atoms. As a result, the technology that we have in the field of physics, but across the board in the physical science field of astronomy, chemistry, physics and earth science. Challenges in Measurements Over the years there have been many adventures that allow for direct measurements within the field of physics, there are still many obstacles and challenges to making direct observations. Physics is the study of energy and matter and the interaction between-both of which are impossible to observe with the naked eye. The first major challenge in making direct measurement in physics is the size of the particles being studied. To solve this issue, physicists study these particles indirectly through things like associated radiation, their energy, or the displacement of other atoms. Almost all measurements that have been made on atoms or subatomic particles has been the result of indirect measurement. The second major obstacle to direct measurement in the field of physics is the Heisenberg Uncertainty Principle. This principle states that it is important to measure both velocity and the location of...

The Journey to Radiography

...called “graceful.” In the first grade, I had dreams of becoming a ballet dancer, so I was enrolled in dance classes. As much as I tried to channel my inner grace, I could not hide my clumsy ways. On one particularly rainy day, my ballet slippers were wet, and I slipped and fell on my right arm, causing it to break. I was taken to the doctor, who put a bright orange cast going from my wrist up to my shoulder. The whole experience of that day is a foggy memory; however, I remember distinctly how fascinated I was by the x-rays taken of my arm, and the machine’s ability to look inside of me. As I entered middle school, I developed a love for soccer. During a game, the ball was kicked high in the air, and an opponent and I collided trying to gain back its control. Unfortunately, the only thing I gained that day was my second broken arm. I was taken to the hospital and examined, again getting x-rays taken to determine the location of the break. As the doctor held up the x-ray to the light, a thousand questions came to my mind. “What bone is that?” “Where is the break?” “Why is the bone showing in the picture, but not the skin?” There were so many things I wanted to know; questions that I didn’t know how to ask at such a young age with my first broken arm. The doctors were all very nice, however, their answers might as well have been in French, because I had no idea what their anatomical lingo meant. At that time, I had no cares in the world and the last thing on my mind was a future career...

Brief History of Medical Imaging

...Brief History of Medical Imaging Medical imaging has played a very significant role in medicine for over the last one hundred years. It is one of the most important diagnostic tools available to doctors and has revolutionized the medical diagnosis of patients. The use of medical imaging has enabled doctors to see inside a patient without having to cut them open. Medical imaging, especially X-ray examinations and sonography which is also known to some as ultrasound, is essential in an everyday medical setting. Preventive medicine as well as healing medicine depends on the proper diagnosis and treatment by physicians, and the use of diagnostic imaging can help evaluate the course of a disease, as well as assess and document the disease in response to the treatment. Medical imaging has rapidly expanded from the first medical image discovered by Professor Wilhelm Conrad Roentgen. During a late night experiment in November of 1895, Roentgen, a physics professor from Germany, was examining Crookes tubes. He noticed that some light had managed to pass through a tube that he had wrapped in thin black cardboard, reflecting on the wall of his dark laboratory. Upon further investigation he found that the light could also be passed through paper, books, and eventually through human flesh. Unintentionally, he had stumbled upon a very important discovery that led to the discovery of what we now call an X-ray. One of the very first x-rays was one that...
