X-rays without film. Fewer X-rays taken. Less radiation exposure. Real-time digital images that can be stored electronically or sent anywhere in the world via telecommunications systems. Such will be the change in X-ray technology with the large-scale, amorphous-silicon X-ray detectors developed by GE Medical Systems (Milwaukee, WI). Conventional X-ray film and chemicals are replaced with computer images and a large-format X-ray detector. Measuring up to 41 @ 41 cm in the active area, GE says these are the largest panels available anywhere. The immense format and high pixel density eliminate the need for optical image reduction. Each pixel delivers up to 16 bits of dynamic-range (contrast) information. Officials at GE predict this will revolutionize the way X-ray images are acquired, analyzed and shared. The manufacture of the detector starts with a pizza-box-size, glass-panel substrate. Photolithographic techniques create photodiodes by applying and patterning successive thin-film layers of silicon, metals, and insulators. A final layer of scintillator material, which converts X-ray photons to visible light, is applied over the array. EG&G (Santa Clara, CA) will have exclusive rights to manufacture the panels, available for medical applications by late 1998 or early 1999. Phone (408) 565-0850.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
The Industrial Internet of Things is bringing a previously reluctant process industry into the wireless fold. The ability to connect smart sensors to the Internet has spiked the demand for wireless devices in process manufacturing, according to the new study from ARC Advisory Group.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
