Diagnostic X-rays used in medical imaging have a large contribution of the population(1)exposure to ionising radiation, at least in developed countries, and it is the most significant source of radiation exposure after natural radon(2). Radiological procedures such as plain films or digital equipments, make up 48% of all diagnostic radiology examinations and these are the reasons for 41% collective dose(3). Progress in diagnostic imaging has contributed significantly to improving health care systems worldwide. One of these advances is digital radiography(4). In the past two decades, digital radiography has replaced film-screen radiography in many medical imaging centers. Today, manufacturers provide a diversity of digital imaging assortment …show more content…
Since the radiology image is very important for the radiologist’s diagnosis, this radiation can affect the quality of the image(7). In the period of 1988–2008, the number of X-ray examinations has increased with 128% in the world(8). It was observed that 80 % of patients referred to hospitals at least need a radiographic examination. Paediatric and infants constitute 10 % of the total number of X-ray examinations (9). Radiation protection in paediatric radiology deserves special attention(10) because of the higher radiation risks compared with adults(11).Therefore some of children tissues or organs are more radiosensitive compared with those of adult patients(12). International Commission on Radiological Protection (ICRP) confirmed that the risk from exposure to ionising radiation is subordinate of the age at exposure(13, 14). Thus, radiation exposure induring childhood is evaluated to have, for certain detrimental effects, an attributable lifetime risk three to four times greater when compared with exposures between the ages of 30 and 40 years and five to seven times greater when compared with exposures after the age of 50 …show more content…
Thus, it is important that radiation doses for children radiology were kept as low as possible and reducing the paediatric dose as much as possible, according to ALARA principle(16). Therefore, for avoiding high doses in the case of exposure from diagnostic and interventional medical procedures(17),the diagnostic reference level (DRL) was established, which was then incorporated by International Commission on Radiological Protection (ICRP)(18). Diagnostic reference levels (DRLs) are a valuable and well-accepted instrument for optimisation the radiation protection for the patient during radiographic examinations(19). DRLs are dose levels in medical imaging based on X-ray or, in the case of radiopharmaceuticals, levels of activity, for routine examinations, for groups of standard sized patients or standard phantoms and for broadly defined types of equipment. DRLs are criterion in order to the assessment of the medical examination performance and hereupon could continuously improve the imaging systems. The continuous improvement of the medical procedure can be accomplished via monitoring the DRL in a certain institution for a given medical device and afterward compared with other hospitals

Too much exposure to ionizing radiation can damage the tissues. Children, young women and fetus are more sensitive to this type of radiation than others (Fahey, 2012). • Maintaining the Highest Level of Safety with NM Workers in nuclear medicine should follow safety rules. While working with radioactive materials, personal protective equipment like gloves, protective eye wear and cloths and in some cases fume hoods must be used. NM procedures must be practiced in special closed places.
With the populations growing and the ages of people increase medical imaging and the diagnosis of diseases seems to be in a higher demand. There is nothing but a positive outlook for a Radiologic tech. There is more to being a Radiologic technician that we never thought about. When we visit the health care office for one of these exams we might not have ever thought about the schooling and experience they have had to go threw to be helping you with what they are helping you with today. We might not have even know who the people are called that give you your x-ray exam , MRI, or your CT scan, but now you do and have background knowledge on who
With the shortage of Radiologists and with the expansion of radiology technology, the need for radiologist assistant has great increased in the past year. Radiologist Assistants are comparable to a physician’s assistant. Both of these jobs assist doctors in performing advance medicine. According to the American Society of Radiologic Technologists, radiologist assistants are registered radiographers who have additional education and certification that qualifies them to serve as radiologist extenders (IN TEXT). The extra education allows a higher pay scale and qualified to perform more procedures.
Radiomics lies at the juncture of what I believe to be extremely exciting science in the coming future of personalized medicine. This is what prompted me to approach Dr. Rivka Colen (desired mentor), of the Department of Diagnostic Radiology, to conduct research in her lab. An interplay between research and clinical treatment such as the way Dr. Colen implements will be one of the grounds that I intend to structure my own practice around. The MD Anderson 1st Year Medical Student Program would help me achieve the first steps towards conducting research in my career as a physician-scientist.
Two hundred monitor units (MU) administered during each trial on a clinically calibrated linear accelerator. Ionization Dmax made with each material using an Exradin A12 Farmer chamber and read by a Keithley 35614 digital dosimeter with no temperature or pressure corrections made. The current in the dosimeter set to +300. The dose on the electrometer measure the output of each trial in Coulombs x
Focusing on radiation burns, the most common body part to be burned is the hand and fingers. These burns occur when radiographers touch or come in close contact with a high intensity radiation emitter (Nde-ed.org, 2009). Also, a common effect in healthcare is radiation sickness. This can occur when an employee is exposed to ionizing radiation for a couple of hours. According to Mayo Clinic, symptoms of radiation sickness can be but not limited to nausea and vomiting, weakness and headache.
Medical Research The growth of technology within medical research has made transformed the impossible into reality. The range of things that technology has helped within the medical field is vast. Medical devices have transformed over the years, much due to technology. Less invasive, and less painful procedures have been on the edge of advancements in medical research and testing. Technology has made it possible to examine diseases at the smallest molecular level possible.
As it has already been discussed in this paper, physicians are responsible for any clinical negligence that may cause harm or injury to the patient. In many journal studies researching radiology, various field cases have been identified and studied. They have shown that radiologists who have not been very often accused of clinical negligence have become in trouble. The errors committed while conducting their radiological work are sometimes caused by their lack of experience or out of their care. But in both cases, they are held to be liable and patients may file lawsuits against
Technology is an ever-growing industry which has become a factor in nearly everyone’s daily schedule in one way or another. As a result of the growth in modern technology, innovations in the medical field have developed extraordinarily in the past decade alone. For instance, there is an extensive variety of imaging equipment which could be used to create reliable results, such as the CT scan or even the X-ray machine. However, Sonography has out-smarted the competition when seeking a non-evasive, safe, and affordable method of visualizing the body to assist in the process of immediate care.
In my opinion, yes there is such a thing as "painless cost control. " Healthcare professionals, insurance companies, and hospital administrators have contributed in making healthcare cost very high. That needs to be controlled because when some insurance companies pay for the fee for services while others pay for capitation or payment for Diem, that creates a lot of confusion and competition in the market leading physicians into a more specialized field and Primary care providers practices certain procedures in their interests which cost more money. Due to that, practices that increase Healthcare cost without creating any benefit for the patients, as well as the insurance companies and the population can be reduced as painless cost control by setting up a universal payment system to pay physicians, specialist, and hospitals.
Some advantages of this technique are that there is no radiation involved, it is good at visualizing soft tissue, and that since it can visualize soft tissue so easily it can identify a multitude of different problems. Some disadvantages are that it is time consuming, expensive, and there is extensive training needed to operate it. The last type of imaging technique that will be covered is conventional radiography which can detect foreign bodies and changes or lesions of the skeletal system and is used when the corpse cannot fit into the CT machine. The advantages of this technique are that it is simple, quick, and cost efficient. However, it uses radiation, cannot make three-dimensional reconstructions, has a superimposed image, and it cannot visualize soft tissue
