redOrbit Staff & Wire Reports - Your Universe Online Treating early breast cancer patients with an advanced form of radiotherapy known as IMRT could reduce the side effects those women experience, according to the results of a randomized trial presented Sunday during the 2nd Forum of the European Society for Radiotherapy and Oncology (ESTRO) in Geneva, Switzerland. IMRT (intensity modulated radiotherapy) is a high-precision form of treatment that delivers an even dose of radiation,...
redOrbit Staff & Wire Reports - Your Universe Online Head and neck cancer patients who experience dry mouth after being treated with radiotherapy can have that symptom reduced if the radiation dose to a salivary gland on the opposite side of the tumor is minimized, researchers from the Netherlands claim in a new study. Dr. Chris Terhaard, an associate professor and radiation oncologist at the University Medical Center (UMC-Utrecht) in The Netherlands, and colleagues discovered a...
Research suggests 'chemo brain' may involve neurophysiological change For many years, breast cancer patients have reported experiencing difficulties with memory, concentration and other cognitive functions following cancer treatment. Whether this mental "fogginess" is psychosomatic or reflects underlying changes in brain function has been a bone of contention among scientists and physicians. Now, a new study led by Dr. Patricia Ganz, director of cancer prevention and control research at...
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 available...

Prostate-Only Radiation Therapy Centers throughout the United States Consistently Demonstrate the Highest Clinical Quality LAWRENCEVILLE, N.J., April 18, 2013 /PRNewswire-iReach/ -- The Premier Prostate Cancer Center, a partnership between AKSM/Oncology and the Urology Care Alliance (UCA), is the latest in a rapidly growing list of prostate-only treatment centers to earn the high honor of a three-year term of accreditation in radiation oncology. The American College of Radiology...
New system sets benchmark in radiation oncology versatility and capabilities HOUSTON, April 18, 2013 /PRNewswire/ -- The University of Texas MD Anderson Cancer Center (Houston, Texas) has purchased two Elekta Versa HD(TM) linear accelerators. The radiation therapy system, which recently received 510(k) clearance from the U.S. Food and Drug Administration, features the versatility to deliver high-volume conventional techniques, in addition to the most advanced linear-accelerator...
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...

The above image looks at the month of March for the three cycles known as Normal Phase, El-Nino, and La-Nina. The data was recorded for the city of Honolulu Hawaii, during the month of March. Remember this is just data for one month during these cycles. Normal: During this cycle incoming solar activity was upwards to 48% efficient for the month, producing less than 50% of the month which is due to the large amount of daily cloud cover that is seen on the island during the early morning and...
The above image looks at the month of March for the three cycles known as Normal Phase, El-Nino, and La-Nina. The data was recorded for the city of Austin Texas. Remember this is just data for one month during these cycles. Normal: During this cycle incoming solar activity was upwards to 60% efficient for the month, producing enough solar energy that only 40% of the month would have not had strong incoming radiation. EL-Nino: This phase provided the area with an extended number of...
Sunglasses are protective eyewear designed to shield the eyes from damaging or discomforting sunlight and high-energy light. They can also work as a visual aid. The ultraviolet radiation from the sun can cause several serious eye problems and many healthcare professionals recommend eye protection. However, since the 1940s sunglasses have been associated with celebrities more so than eye protection. James Ayscough experimented with tinted lenses in the mid-18th century although they were...
The bolometer, invented in 1878 by Samuel Pierpont Langley, measures the energy of incident electromagnetic radiation. It consists of an absorptive element connected to a heat sink through a thermal link. The absortive element raises its temperature above that of the heat sink when radiation impinges on it. The higher the energy the higher the temperature rises. Old bolometers used metals while newer ones used semiconductors and superconductors as the absorptive elements. Bolometers can...
A telescope, designed to aid the observation of remote objects, collects some form of electromagnetic radiation (such as visible light). The Netherlands developed the first known practical telescope in the 17th century. The term "telescope" was termed in order to describe Galileo's instruments in 1611. However, Galileo was not the inventor of the telescope. It was Hans Lippershey, Zacharias Janssen, and Jacob Metius who are credited with the creation of the telescope. In 1668, Isaac Newton...
