Virtual Reality Headset Could Enable Immersive Remote Surgery

Wednesday, July 24th, 2013

A novel headset that completely immerses gamers in a virtual reality has the potential to bring some real-world advances to medical technology. Plextek Consulting (Cambridge, UK) is using the Oculus Rift headset to apply what it calls immersive telepresence to remote examinations and diagnostics. The video communications system (pictured) that simulates ...

Step Aside Google Glass? Fraunhofer’s Data Glasses Said to Truly Augment Reality

To maintain sterility, he can’t touch anything else. If he wants to ...

Scientists Improve X-Ray Microscopic Imaging

Friday, February 8th, 2013

X-ray microscopy requires radiation of extremely high quality. To obtain sharp images, instrument and sample must stay absolutely immobile even at the nanometre scale during recording. Researchers at the Technische Universität München and the Paul Scherrer Institute in Villigen, Switzerland, have now developed a method that relaxes these hard restrictions. ...

New MRI Technique Could Lead to Improved Diagnosis of Neuro-Degenerative Diseases

Tuesday, November 13th, 2012

Researchers at the University of Nottingham have developed a new MRI technique that could aid in the diagnosis and monitoring of neuro-degenerative diseases. The technique shows more detailed information related to the size and direction of nerve fibres, which could help clinicians identify abnormalities in the brain. Typical MRI research ...

Advanced In Vivo Imaging Technology One Step Closer to Clinical Use

Low-Cost Device Could Bring Affordable Ultrasound to Developing Regions

Friday, September 14th, 2012

When sonar technology expert Jeff Neasham and his wife expected a child, they realised how privileged they were to have access to ultrasound technology. Over 250,000 women die annually from complications during pregnancy, but 99% of these deaths could be prevented, according to UN statistics. Access to ultrasound is key ...

Finnish Researchers Combine MEG and MRI in New Device

Thursday, August 2nd, 2012

Finnish researchers have created a device for the mapping of the human brain that combines magnetoencephalography (MEG) and magnetic resonance imaging (MRI), Medical News Today reports. The imaging device will allow patients to only undergo one imaging session instead of two. It can also overcome some of the shortcomings of ...

Medtech Week Recap: Prosthetic Legs Take Centre Stage in 2012 Summer Olympics Debate

Monday, July 30th, 2012

In 2007, a German report led to the International Association of Athletics Federations banning the runner Oscar Pistorius from participating in the Olympics. The report found that his two prosthetic legs gave him an advantage because they absorb levels of stress that his ...

Algorithms Enable Remote Diagnostics, at First Blush

Wednesday, July 25th, 2012

You may blush because you are embarrassed, but software algorithms developed by MIT computer scientists see beyond the emotions. The redness of your face can be an indicator of your pulse, and it can be measured remotely via video, reports Technology Review.

Radiation-Free Technique Detects Breast Tumours with the Use of Ultrasound and Photoacoustics

Tuesday, May 8th, 2012

An imaging device developed by researchers in Netherlands combines photoacoustics (light-induced sound) with ultrasound to detect breast tumours, according to a press release from The Optical Society (OSA). The device, Twente Photoacoustic Mammoscope (PAM), was recently used in clinical testings. Preliminary results were reported yesterday in the open-access journal Optics Express.

3-D X-Ray Technique Depicts Fibres Controlling Heart Rhythm

Wednesday, May 2nd, 2012

[caption id="attachment_27775" align="alignleft" width="126" caption="The heart's conducting tissue"][/caption] When surgeons try to repair a malformed heart, one of the major concerns is to avoid damage to the conducting tissue that distributes electrical waves that trigger heart beats. Until now, experts have had a limited understanding of this network of conducting tissue. A ...
