Siemens has presented the world's first ultrasound system with wireless transducers. The system's transducers, which can be easily operated with one hand, transmit ultrasound images via radio waves to the screen on the base console. The elimination of cables is particularly helpful in operations or during invasive procedures in which the needle visualization needs to be monitored using ultrasound technology. That's because transducer cables can obstruct the people who operate the machines, and despite their sterile protective coverings, the cables can pose a risk in terms of infections. The wireless Acuson Freestyle system transducers function reliably up to three meters from the console and are equipped with remote control buttons for adjusting the image settings. To make wireless data transmission possible, Siemens engineers sharply reduced the amount of data that must be transferred between the transducer and the console. http://medicalxpress.com/news/2013-05-wireless-ultrasound-transducers-physicians.html Other Mon, 20 May 2013 08:00:01 EST news288252886 (HealthDay)—In patients undergoing computed tomography (CT) colonography, reducing the tube voltage from 120 kVp to 100 kVp significantly reduces radiation dose while minimally reducing image quality, regardless of patient size, according to a study published in the March issue of Radiology. http://medicalxpress.com/news/2013-03-lowering-ct-tube-voltage-colonography.html Cancer Thu, 07 Mar 2013 16:30:01 EST news281892108 For the first time, Bochum clinicians have been able to show on the basis of a large sample, that it is possible to examine children's heads in the MRI scanner without general anaesthesia or other medical sedation. In many cases it was sufficient to prepare the young patients for the examination in an age-appropriate manner in order to take away their fear of the tube. And the results speak for themselves: of the 2461 image sequences recorded with 326 patients, the participating radiologists classified 97 percent as "diagnostically relevant". http://medicalxpress.com/news/2012-11-magnetic-resonance-scanner-cuddly-toy.html Other Fri, 16 Nov 2012 09:39:07 EST news272281135 New guidelines for CT-guided biopsies of lung nodules significantly reduce radiation exposure allowing individuals the benefit of the procedure, which may cut down on overall lung cancer deaths.
