Proton imaging resolution boosted in one step

An international team of researchers has developed a statistical tool that improves the resolution of proton imaging in a single step, without any prior radiographic information. The tool has the potential to boost the accuracy of proton therapy so that less radiation is delivered to healthy tissue.

Software as good as hardware for PET gating

Researchers have demonstrated that software is as good as, if not better than, hardware when it comes to filtering out patient motion during PET. In blind tests, reviewers could spot no difference most of the time, and when differences were seen, software gating was more likely to be rated as superior.

Lead protects pacemakers from radiation

Lead shields provide a simple and inexpensive way to reduce radiation delivered to pacemakers during radiation therapy, according to a new study. The protection is modest in many instances, but can in some cases reduce radiation by 40%, cutting the risk of pacemaker failure.

French report breakthrough in medical isotopes

Medical physicists from Nantes, France, have generated a series of medical isotopes from the irradiation of thorium-232. One of the products decays into a promising isotope for alpha radionuclide therapy, while another product is a sought-after isotope used in diagnostics.

MRI and PET tackle Alzheimer's diagnostics

A new window into the development of Alzheimer's disease may have been opened up by German researchers. They have combined two noninvasive imaging techniques to study b-amyloid plaques and found a connection between their formation in cerebral blood vessels and reduced blood flow in the brain.

3D ultrasound goes ultrafast

Scientists in France have developed a new type of ultrasound that can produce 3D videos at thousands of frames per second. It builds on 2D ultrafast ultrasound, and has already enabled its creators to witness blood flowing through the chambers of a human heart in real-time.

MR-guided HIFU proves safe for liver ablation

MR-guided high-intensity focused ultrasound (MR-HIFU) is "sufficiently reliable and safe" to begin clinical trials in the liver. That's according to researchers in Finland and the Netherlands, who have assessed the use of the technique in a clinically acceptable setting.

Advanced MRI helps unravel mysteries of babies' brains

Some 85 billion neurons and upwards of 100 trillion connections -- the adult human brain is the most complex object in the known universe. But how does such a rich neural network grow from a tiny fetus? And how does that growth affect the way our brains ultimately function?

Superresolution ultrasound maps the brain

Researchers have overcome an inability of ultrasound to map capillaries and other vessels in the brain by injecting micrometer-sized bubbles into the bloodstream. Although the technique has been demonstrated only on a model brain so far, it's a promising new way to map the brain's vascular networks.
