In this short video with Elekta, filmed at ASTRO 2021, Francisco Nunez introduces ProKnow. The cloud-based ProKnow software is designed to improve quality in radiation therapy. It allows users to perform individual patient analysis, as well as data analysis across large populations of patients, to evaluate treatment outcomes and improve cancer care.

In this short video, filmed at ASTRO 2021, Siemens Healthineers’ Gabriel Haras introduces the company’s portfolio of artificial intelligence (AI)-based products. Such technologies support the entire care pathway for cancer patients, from screening and diagnostics to treatment and follow-up, including innovations such as AI-based autocontouring and generation of synthetic CT from an MRI scan for

As radiation therapy techniques continue to evolve, and the complexity of those treatments increases, quality assurance (QA) processes become more complex alongside. In this short video, filmed at ASTRO 2021, Elekta’s Heath Britt explains how the company is introducing a range of products to improve the QA workflow. Elekta’s portfolio, which includes machine QA and

In this short video, filmed at ASTRO 2021, Justin Turpin introduces the Elekta Unity MR-guided radiotherapy system. Elekta Unity provides real-time imaging whilst the gantry is rotating and the MLCs are moving, enabling treatments to be tailored according to changes in the patient’s tumour and surrounding anatomy. Turpin explains how new sequencing enables users to

The James Webb Space Telescope (JWST) is scheduled to launch on 24 December. To mark the event, Physics World is publishing a series of blog posts on the telescope’s technological innovations and scientific missions. This post is the first in the series.

Griffin said the United States now has to play catchup and needs to increase funding for missile-tracking satellites to help defend against hypersonic threats.   WASHINGTON — China’s successful demonstration of a hypersonic glide vehicle — a weapon that is boosted to space, orbits the Earth and reenters the atmosphere before it strikes a target

TAMPA, Fla. — Investors that rescued Anuvu from bankruptcy in March have thrown $50 million behind plans for the mobile connectivity provider to have its own constellation of small geostationary-orbit (GEO) satellites. The growth capital will support the first two satellites Anuvu ordered in July from Astranis as part of a planned eight-strong constellation, building

WASHINGTON — The Defense Advanced Research Projects Agency in a new program will explore options to conduct biomanufacturing in space, using biological systems like microbes to construct materials for use in orbital operations. The project, led by DARPA’s biological technologies office, is called B-SURE, short for biomanufacturing, survival, utility and reliability beyond Earth. “The B-SURE

Spin crossover signature: disappearing plates and plumes. (Courtesy: Columbia Engineering) Researchers have identified a quantum phase transition taking place in iron more than 1000 kilometres deep within the Earth’s mantle. This transition, known as a spin crossover, also occurs in nanomaterials used for recording information magnetically, meaning that the effect stretches from the macro- to

Lt. Gen. Saltzman: ‘We are seeing a shift to where the first strike advantages are encountered in space’ WASHINGTON — China and Russia for decades have watched the United States display its military power, much of it enabled by satellites in space. China’s recent demonstration of an orbital hypersonic weapon and Russia blowing up a

WASHINGTON — A SpaceX Falcon 9 successfully launched a NASA mission that will deliberately collide with a near Earth asteroid to test a technique that could be used to deflect the trajectory of any future asteroid on a collision course with the Earth. The Falcon 9 lifted off on schedule at 1:21 a.m. Eastern Nov.

Their main drawback is that they can generally be made either stiff or tough, but not both at the

HELSINKI — Spanish launch startup PLD Space has debuted a fully assembled Miura 1 reusable suborbital rocket as a step towards its inaugural flight in 2022. The Miura 1 was unveiled at the National Museum of Natural Science in Madrid Nov. 16. Next, it will be returned to the PLD Space base at Teruel Airport

TAMPA, Fla. — OneWeb is considering options to remove one of its broadband satellites from low Earth orbit after it failed following a software issue last year. “We are looking at all potential suppliers to address de-orbit as and when the tech is safe,” said Chris Mclaughlin, OneWeb’s chief of government, regulation and engagement. The

HELSINKI — A Chinese Kuaizhou-1A rocket launched the experimental Shiyan-11 satellite for China’s main space contractor from northwest China late Nov. 24. The 19.4-meter-long Kuaizhou-1A lifted off from a transporter erector launcher at 6:41 p.m. Eastern Wednesday, rising into pre-dawn skies over the Jiuquan Satellite Launch Center in the Gobi Desert. Aboard was the classified
