Working together at Henry Ford Hospital in Detroit, medical physicists and clinicians have developed a new procedure that treats spinal tumors and relieves patient discomfort faster that current treatments. Called intensity-modulated spinal radiosurgery, this technique pinpoints a tumors location to deliver a powerful dose of radiation that avoids healthy areas of the spinal cord, kidneys, and lungs. This research was presented last month at the annual meeting of the American Association for Physicists in Medicine in Montreal.
"Each year roughly 100,000 people are diagnosed with spinal tumors in the U.S.," says Fang-Fang Yin, a medical physicist at Henry Ford Hospital Systems, "Most spinal tumors are located very close to the spinal cord, which is sensitive to radiation."
Because the spinal cord is so vulnerable, current spinal tumor treatments such as conventional radiotherapy and decompressive surgery require multiple lower does of radiation to protect the spinal cord while treating the tumor.

Two prominent X-ray emission lines of highly charged iron have puzzled astrophysicists for decades: their measured and calculated brightness ratios always disagree. This hinders good determinations of plasma temperatures and densities. New, careful high-precision measurements, together with top-level calculations now exclude all hitherto proposed explanations for this discrepancy, and thus deepen the problem.
Hot astrophysical plasmas fill the intergalactic space, and brightly shine in stellar coronae, active galactic nuclei, and supernova remnants. They contain...
In living cells, enzymes drive biochemical metabolic processes enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. Researchers now identified an enzyme that, when illuminated with blue light, becomes catalytically active and initiates a reaction that was previously unknown in enzymatics. The study was published in "Nature Communications".
Enzymes: they are the central drivers for biochemical metabolic processes in every living cell, enabling reactions to take place efficiently. It is this very...
Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick out even very small tumors from normal tissue. The work is published May 25 in the journal Nature Nanotechnology.

Microelectronics as a key technology enables numerous innovations in the field of intelligent medical technology. The Fraunhofer Institute for Biomedical Engineering IBMT coordinates the BMBF cooperative project "I-call" realizing the first electronic system for ultrasound-based, safe and interference-resistant data transmission between implants in the human body.
When microelectronic systems are used for medical applications, they have to meet high requirements in terms of biocompatibility, reliability, energy...
