The American Society for Radiation Oncology (ASTRO) has issued a new white paper, “Assuring Safety and Quality in Image Guided Delivery of Radiation Therapy,” that recommends best practices to improve the safety and effectiveness of image guided radiation therapy (IGRT), according to the manuscript published as an article in press online in Practical Radiation Oncology (PRO), the official clinical practice journal of ASTRO. The executive summary and supplemental material are...

The estimated size of chest lymph nodes and lung nodules seen on CT images varies significantly when the same nodes or nodules are examined using lower versus higher doses of radiation, a new study shows. The size of lymph nodes and lung nodules is an important determinant of treatment and treatment success. The study, conducted at Massachusetts General Hospital in Boston, used a 3D image processing tool to quantitatively measure the volume of the lymph nodes and lung nodules. "We found...

Radiation dose reduction has moved to the forefront of importance in medical imaging with new techniques being developed in an effort to bring doses down as low as possible. What difference can these techniques make? Researchers at Indiana University School of Medicine aimed to find out. "We conducted a study to quantify dose reduction, comparing two years' worth of data and 11,458 abdomen and pelvic CT exams," said Dr. Jonas Rydberg, lead author of the study. Data on 5,707 consecutive CT...

An algorithm that takes the patient's size into consideration can cut radiation dose by 41% in lumbar spine CT without compromising the diagnostic quality of the images, a new study shows. Researchers at Yeouido St. Mary's Hospital in Seoul, Korea examined 107 patients using semi-automated attenuation-based tube potential selection which optimized tube potential at 100 kilovoltage, rather than the standard 120 kilovoltage. Decreasing the kilovoltage decreased the radiation dose from a mean...

Nuclear Fallout
2013-04-01 10:26:30

Nuclear fallout, or just simply fallout, known also as Black Rain, is the residual radioactive material that is propelled into the upper atmosphere after a nuclear black or a nuclear reaction that is conducted in an unshielded facility. It is so called because it "fall out" of the sky after the explosion and the shock wave have passed. It most commonly refers to the radioactive dust and ash that is created when a nuclear weapon explodes, but such dust can also come from a damaged nuclear...

Solar Radiation -- Solar radiation is radiant energy emitted by the sun due to nuclear fusion reactions. Fusion is the process whereby stars produce huge quantities of energy from the fusion of hydrogen or helium, in one of the most efficient processes of energy generation. The radiation referred to is usually electromagnetic energy, particularly infrared radiation, visible light, and ultraviolet. Some stars are known to emit radiation of other wavelengths. Solar neutrinos are a...
