Latest laser ablation Stories
Men with low-risk prostate cancer who previously had to choose between aggressive treatment, with the potential for significant side effects, and active surveillance, with the risk of disease progression, may have a new option. Focal laser ablation uses precisely targeted heat, delivered through a small insertion and guided into the prostate by magnetic resonance imaging, to burn away cancerous cells in the prostate. A small, phase 1 trial, to published early online in the journal...
Engineers have discovered details about the behavior of ultrafast laser pulses that may lead to new applications in manufacturing, diagnostics and other research. Ultrafast laser pulses are used to create features and surface textures in metals, ceramics and other materials for applications including the manufacture of solar cells and biosensors. The lasers pulse at durations of 100 femtoseconds, or quadrillionths of a second, and cause electrons to reach temperatures greater than 60,000...
For people who care about the appearance of their legs, compression hosiery, which is universally recommended for both surgical and non-surgical treatments of varicose veins and spider veins, works to promote leg health and may also be worn to alleviate aching, tired, or restless legs. If vein problems are left untreated, you may develop pain, fatigue, and swelling that can lead to skin discoloration, bleeding, and leg ulcers. Dr. Robin Fleck, MD, founder and medical director of Vein...
Physicians at Mayo Clinic's Florida campus are among the first in the nation to use a technique known as MRI-guided laser ablation to heat up and destroy kidney and liver tumors. So far, five patients have been successfully treated "” meaning no visible tumors remained after the procedure.They join their colleagues at Mayo Clinic's site in Rochester, Minn., who were the first to use laser ablation on patients with recurrent prostate tumors.Although the treatment techniques are in the...
Laser ablation is well known in medical applications like dermatology and dentistry, and for more than a decade it has been used to vaporize materials that are difficult to evaporate for high-tech applications like deposition of superconductors. Now researchers in the Journal of Applied Physics, which is published by the American Institute of Physics have studied the properties of femtosecond laser ablation plumes to better understand how to apply them to specialized films.Salvatore Amoruso...
HOUSTON, Aug. 30 /PRNewswire-USNewswire/ -- As one of the leading medical centers in the U.S. diagnosing and treating twin-to-twin transfusion syndrome (TTTS), Texas Children's Fetal Center is proud to announce the successful completion of its 200th TTTS laser ablation surgery. To view a video about TTTS and learn about the important questions parents should ask their doctor, see: http://bit.ly/cgmn3W. There have been various treatment options used in an attempt to correct the effects of...
A laser technique best known for its use to remove unwanted tattoos from the skin is finding a second life in preserving great sculptures, paintings and other works of art, according to an article in ACS' monthly journal, Accounts of Chemical Research. The technique, called laser ablation, involves removing material from a solid surface by vaporizing the material with a laser beam.Salvatore Siano and Renzo Salimbeni point out that laser cleaning of artworks actually began about 10 years...
A team of Spanish and British scientists has developed a "laser ablation" method that makes it possible to detect variations in the sulphur isotopes of a single hair over time. This information shows up changes in a person's eating habits and their movements between different countries, which could help police to undermine the alibis of international terrorists.A group of researchers from the LGC Chemical Metrology Laboratory in the United Kingdom and the University of Oviedo,...
U.S. National Institute of Standards and Technology scientists say they've created a nanotube coating to enable measurements of high-power military lasers. Researchers said the technology allows the military to quickly and easily calibrate high-power laser systems, such as those intended to defuse unexploded mines. They said their achievement rests with a novel nanotube-coated power measurement device that can measure the light emitted by 10-kilowatt laser systems -- light a million times...
The U.S. military can now calibrate high-power laser systems, such as those intended to defuse unexploded mines, more quickly and easily thanks to a novel nanotube-coated power measurement device developed at the National Institute of Standards and Technology (NIST).The new laser power meter, tested at a U.S. Air Force base last week, will be used to measure the light emitted by 10-kilowatt (kW) laser systems. Light focused from a 10 kW laser is more than a million times more intense than...
