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. ...

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 ...

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 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 ...

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.

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 ...

A new imaging method called High Definition Fibre Tracking (HDFT) can reveal broken neural connections in the brain. The method uses data from MRI scanners and processes it through computer algorithms. It was developed by researchers at University of Pittsburgh (PA, USA). The research was reported online in the Journal ...
