New technology developed by GE may help radiation oncologists more accurately target tumors
A new imaging technology developed by GE Medical Systems and currently being evaluated at the University of Pittsburgh Medical Center (UPMC) may allow radiation oncologists to precisely track tumor movement and avoid excess doses of radiation for patients under treatment for cancer. Preliminary results at UPMC demonstrate that Advantage™ 4D (Adv4D) limits the exposure of radiation to healthy tissue surrounding a tumor by allowing radiation oncologists to precisely visualize and assess its structure and movement.
"One of the challenges of treatment planning for radiation therapy is pinpointing radiation precisely to target a tumor and decreasing the amount of healthy tissue that may be exposed to radiation," said Andrew Wu, Ph.D., director of medical physics at UPMC. "Tumors are akin to moving targets. As a patient inhales and exhales, the tumor moves, making it challenging to target the tumor and to avoid exposure of radiation to the area that surrounds the tumor."

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
