SPECT/CT dramatically cuts radiation dose in some breast cancer patients

December 17, 2010

Dose reduction at one time played second fiddle to image quality, but today it enjoys top billing. New algorithms are coming into play in CT, radiography, and fluoroscopy to maintain image quality at traditional levels by processing out the noise that sneaks in during low-dose exams. In some cases, fear of radiation has gotten so bad that patients forego CT and other sources of ionizing radiation all together.

December 14, 2010

GE introduces wide-band wireless to avoid x-ray traffic jam

December 09, 2010

Wireless x-ray detectors have come into vogue and are now available from a half dozen vendors. They are being offered singly, as a digital upgrade for analog x-ray systems, for example, or as the core of portable and advanced fixed radiography systems. GE Healthcare is among those offering a portfolio of such choices. But GE is putting a twist on its wireless detector, dubbed the FlashPad, one that company execs say will prevent what could be a ticklish problem in the future. This potential problem stems from the success of digital radiography.

Philips RF remote product offers workflow advantages

December 01, 2010

Remote radiography and fluoroscopy systems traditionally have appealed more to Europeans than to practitioners in the U.S. But Philips is betting the time-and design of its new Juno DRF-are right to make a change in old habits. The Juno DRF remote-controlled flat-detector system, recently cleared by the FDA, offers enhancements that Philips Healthcare is promoting in its RSNA booth as the means to faster workflow and patient throughput and maximized return on investment.

Philips unveils new CT and PET/CT platforms

November 30, 2010

Philips is adding to its portfolio a new line of CT scanners and a new line of PET/CTs based on dose-saving technologies.

Philips will not stop making these older models, but will feature them in its product portfolio as alternatives to the latest releases.
