Heavy smoker? Consider annual CT scans

The National Cancer Institute isn't changing one of its key messages: don't smoke--it'll kill you.

But the mortality data from its ongoing National Lung Screening Trial (NLST) involving more than 53,000 current and former heavy smokers ages 55 to 74 is so striking that the institute announced initial findings today, ahead of a more comprehensive report.

What the trial shows is that there have been 20 percent fewer deaths from lung cancer among trial participants who receive an annual low-dose CT scan than those who receive an annual standard chest X-ray.

While CT scans are already considered valuable … Read more

High-tech hair brush improves optical brain scans

When it comes to measuring oxygen levels in the brain to chart neurological activity--a technique called functional near infrared spectroscopy (fNIRS)--things can get a little hairy. Literally. As in, the patient's hair gets in the way.

So researchers at the University of Texas have engineered a novel device, which they call a "brush optrode" (variant of word optode), whose fiber tips thread past hair to increase scalp contact, thereby improving signal levels as well as overall cost and efficiency of the optical scanning technique. They will present their findings at the Optical Society's 94th annual … Read more

Basic protection

The bottom line: A new name heralds some big changes for Trend Micro's Titanium suites. The overhaul to Titanium Antivirus+ 2011 brings users a faster suite with a smaller system impact. However, Trend Micro's new security engine is too untested to be able to recommend it.

Review: Trend Micro's updates for 2011 bring a substantially overhauled suite, from the name down to its detection engine. The new version brings a new interface, new cloud-based detection engine, and new features that, on whole, are changes as impressive as those that Norton has gone through the past few years. … Read more

Victimized by a 'legitimate' drive-by download

I know very well to uncheck the preselected software offers that accompany so many program updates these days. In August 2009, I edited a story by Susan Bradley in the Windows Secrets newsletter describing how Sun Microsystems, Apple, and Microsoft were making money by pushing unwanted software on unsuspecting customers.

So I have only myself to blame for the half-hour I wasted this weekend making sure my laptop's antivirus protection was active and up-to-date. That doesn't make me feel any better about Adobe preselecting the download of McAfee's Security Scan Plus freeware along with the Flash Player … Read more

IBM helping Europe scan historical documents

IBM and the European Union are teaming up to offer a better way to scan the massive collection of Europe's treasured historical documents.

Expanding on an existing collaboration project, Big Blue and the EU will now be working with more than two dozen libraries, research institutes, universities, and companies across Europe to help them digitize their rare books and documents.

The project known as Impact (Improving Access to Text), is using new tools and tapping into crowd sourcing to speed up the mass digitization process and ensure that the scanned documents are as accurate as possible. Impact will also … Read more

Drivers ed

Device drivers allow hardware devices and computer programs to interact, so they're obviously an integral part of proper computer function. When drivers go missing or become out of date they can slow down system performance and create other problems. DriverGuide DriverScan is an easy way to scan your computer for outdated drivers. Unfortunately, although the program is free, you're going to have to pay if you want to update your drivers with it.

DriverGuide DriverScan is incredibly easy to use, which is a good thing, because there's no Help file. The program opens with a plain screen … Read more

AT&T embraces bar code scanning with new app, services

Bar code readers and scanning applications have slowly been gaining popularity in the United States thanks to apps such as ShopSavvy, Compare Everywhere, and Google Shopper. AT&T is jumping on board with its own bar code offerings that the carrier announced today.

Designed for Android and BlackBerry phones, AT&T's new Mobile Barcode Services primarily serve as shopping tools, according to the carrier. First up is the free AT&T Code Scanner app that lets users scan 2D and 1D barcodes to receive coupons, promotional materials, movie trailers, and more. To download the free app … Read more

How video game processors could save lives

Are you dreading upgrading your graphics processor yet again just so you can get lost in the alien-infested urban jungle of Crysis 2? Rest assured that the immersive power of these state-of-the-art video processors is now being used for more than just visual pleasure.

A new technique for processing X-rays appears to lower the radiation patients are exposed to during cone beam computed tomography (CBCT) scans by a factor of 10 or more, according to researchers at the University of California, San Diego.

The research is being presented this week at the American Association of Physicists in Medicine's 52nd annual meeting in Philadelphia.

Lead author Xun Jia, a UCSD postdoctoral fellow, based his team's work on recent advances in compressed sensing by developing a CT reconstruction algorithm for graphics processing unit platforms (GPU cards being used for 3D computer graphics, often in video games), thereby increasing computational efficiency to reconstruct a cone beam CT scan in just minutes.… Read more
