X-rays may double the risk of cancer for obese patients

A new study has revealed that obese patients who undergo an x-ray are at a greater risk of developing cancer due to the higher dose of radiation required.

Study presents new opportunities for targeted, healthy tissue-sparing cancer therapy

Medical physicist Dr. Aswin Hoffmann and his team from the Institute of Radiooncology - OncoRay at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) are the first researchers worldwide to combine magnetic resonance imaging (MRI) with a proton beam, thus demonstrating that in principle, this commonly used imaging method can indeed work with particle beam cancer treatments.

Scientists figure out way to measure fetal cardiac electrical activity

Electrodes are placed on the patient's chest area to record cardiac electrical activity - e.g. to determine whether the heart rhythm is so irregular that treatment is required; a type of medical examination for which ECG serves well as a diagnostic tool.

Validation of non-invasive stent monitoring techniques

Researchers from the Research Institute Germans Trias i Pujol, the Biomedical Research Networking Center on Cardiovascular Diseases, the University of Barcelona and the the Universitat Politècnica de Catalunya have created a new field probe to detect in a non-invasive and non-ionizing way the presence of metallic stents as well as their potential structural failures through microwave spectrometry.

Could 'natural adaptive therapies' be a better way to keep cancer under control?

While many cancer therapies initially can be very successful, tumors often return and spread when remaining cancer cells develop resistance to treatment.

Pitt bioengineering student develops realistic phantom head for MR research

Phantoms are not just ghostly figures of our imagination, they are also numerical or physical models that represent human characteristics and provide an inexpensive way to test electromagnetic applications. Sossena Wood, a bioengineering PhD candidate at the University of Pittsburgh, has developed a realistic phantom head for magnetic resonance research in the Swanson School of Engineering.

Researchers simulate how different breast tissues respond to heat from MRIs

No woman's breast tissue is the same, so MRIs detecting and monitoring cancer shouldn't treat them all the same.

New multidisciplinary microsurgery microscope, PROVIDO, introduced by Leica

Leica Microsystems launches the first PROVIDO multidisciplinary microsurgery microscope, that sets the bar for a new standard for visualization quality in its class. The top-of-the-line optics and illumination combined for the first time into a responsive, stable floor stand, allow surgeons to see more, simply. PROVIDO features FusionOptics technology only from Leica Microsystems that gives unparalleled depth of field and detail perception at the same time.

'Mystery illness' afflicting diplomats linked to RF/MW radiation

Writing in advance of the September 15 issue of Neural Computation, Beatrice Golomb, MD, PhD, professor of medicine at University of California San Diego School of Medicine, says publicly reported symptoms and experiences of a "mystery illness" afflicting American and Canadian diplomats in Cuba and China strongly match known effects of pulsed radiofrequency/microwave electromagnetic radiation.

UTSA enters Guinness World Records for creating smallest medical robot

It can't be seen with a human eye. It doesn't look anything like C-3PO or R2-D2, or even BB-8. But, nevertheless, it is a robot and its creators from The University of Texas at San Antonio are now world record holders in the Guinness World Records for creating the Smallest Medical Robot.

Magnetic gene in aquarium fish could open doors to treatment for epilepsy, Parkinson's

An aquarium fish that senses the Earth's magnetic field as it swims could help unlock how the human brain works and how diseases such as Parkinson's and other neurological disorders function.

Nanostructured sensor system offers active monitoring of brain aneurysm treatment

Implantation of a stent-like flow diverter can offer one option for less invasive treatment of brain aneurysms – bulges in blood vessels – but the procedure requires frequent monitoring while the vessels heal.
