The Evolution of Radiography: from Analog to Digital Systems

For the better part of the 20th century, film or screen radiology was the prevailing method to produce x-ray images. This analog system was able to provide physicians with a hard-copy image, which they could hold up against light to view and diagnose x-ray images. With the advent of digital systems, patient images would become available almost instantaneously anywhere in the care facility or around the globe. Computed radiography (CR) and digital radiography (DR) are not always perfect. This paper […]

The History and Advancements of Radiography in Different Countries

Wilhelm Conrad Roentgen, a professor from Germany, is credited with being the original founder of radiography in 1895. He stumbled upon this observation while experimenting with a cathode-ray tube. Through his experimentation, he observed crystals that gave off a fluorescent glow near the tube he was using, and from this, he was able to discover a ray that had the capability of passing through a heavy sheet of paper, creating a fluorescent green light. (History of Radiography, 2001) Roentgen was […]

It has become a significant issue in the world today, especially in the developing world. This is just because of the high cost of treating and managing it. It is a disease that is mainly characterized by the growth and multiplication of cells in the human body, making it […]

The Role and Benefits of Interventional Radiology

There are many modalities in radiology, such as magnetic resonance imaging (MRI), computed tomography (CT), radiography, fluoroscopy, ultrasound, interventional radiography (IR), and nuclear medicine. Each modality has its own radiology technician that assists with running the exam. Each technologist is specifically trained in his or her modality. Interventional radiology is part of the operating room. Interventional technologists, or IR technologists, assist the doctors in the operating room. IR technologists have an important role in the patient’s experience by greeting the […]

X-Rays Helping Diagnose Child Abuse

Not too long-ago physical discipline was a common practice and seen as normal part of educating children. It was a common accepted belief that parents had the right to educate and discipline their children in the way they considered to be right. Children’s education was considered to be a private matter between parents and their children which no one had the right to intervene. It was until some physicians started a movement to make people aware of their findings in […]

Exploration of External Beam Radiation Therapy Treatment for Breast Cancer Patients

In 1896, Wilhem Conrad Roentgen (a German physics professor) presented a lecture introducing the x-ray. There was immediate worldwide excitement and systems were quickly developed to utilize this new technology and within three years x-rays were being used to treat cancer. The American Cancer Society (2014) describes that it was common for early radiologists use themselves to test the strength of the radiation coming from machines. They would use the skin on their arms to find a dosage that would […]

Radiation Protection for Angiography Procedure

1. Describe the practice of radiation protection for angiography procedure. Fluoroscopic procedure produces the greatest patient radiation exposure rate in diagnostic radiology. Therefore the radiation protection in fluoroscopy is very important. Several feature and techniques in fluoroscopy are designed for protection to the patient during fluoroscopic procedure. a) Protection to Patient * A dead-man switch is a device (switch) constructed so that a circuit closing contact can only be maintained by continuous pressure on the switch by the operator. Therefore, […]
