CT scan reveals ancient long-necked gliding reptile

...dded in stone, but thanks to an industrial-size CT scanner at Penn State's Center for Quantitative Imaging, the bone structure and behavior of these small creatures are now known. The new gliding reptile is named Mecistrotrachelos apeoros meaning "soaring, long-necked" and was found at the Solite Quarry t...

Dinosaur hearing, listening to muscle noise, quieter cubicles

...se that may pose a hazard to both participants and scanner operators. Acoustical researchers are devising various approaches to making the machines quieter. A UK team (including Deborah Hall, MRC Institute of Hearing Research, Nottingham, d.hall@ihr.mrc.ac.uk ) will present an active noise control system ...

Bones in motion: Brown scientists to create new 3-D X-ray system

Ultrasound upgrade produces images that work like 3-D movies

... it has now modified the commercial version of the scanner to produce an even more realistic perception of depth. Paired images seem to pop out of the screen when viewed with the special glasses. The researchers created an updated version of the image-viewing software found on clinical ultrasound scanners...

UCLA: How does your brain respond when you think about gambling or taking risks?

... in a functional magnetic resonance imaging (fMRI) scanner at UCLA's Ahmanson–Lovelace Brain Mapping Center, where researchers studied their brain activity; the technique uses magnetic fields to spot active brain areas by telltale increases in blood oxygen. For each question, the participants answered whe...

New fMRI technology making brain tumor surgery safer

...rformed several days prior to surgery on a 3 Tesla scanner at West Image, a Cincinnati imaging facility owned by Set Shababian, M.D. “We perform various language, motor and vision tasks with the patient in the MRI scanner,?Dr. Leach explained. FMRI scanning takes approximately 75 minutes, about 30 minutes...

New brain-chemistry differences found in depressed women

...re lying in the positron emission tomography (PET) scanner having their brains imaged. The women recalled the death or serious illness of a friend or family member, a past divorce or breakup with a boyfriend, or other major difficulties. They also had their brains imaged during a neutral emotional state. ...

NHGRI aims to make DNA sequencing faster, more cost effective

... on an immobilized primer/template. A fluorescence scanner will be used to scan and identify hundreds of thousands of molecules at once. Then the cycle will be repeated. This phased award will increase if specific milestones are met in the initial experiments. J. Michael Ramsey, Ph.D., University of Nor...

Fast test for low blood flow in dogs detects early heart trouble

Radiologists attempt to solve mystery of Tut's demise

...e said. "The electricity suddenly went out, the CT scanner could not be started and a team member became ill. If we weren't scientists, we might have become believers in the Curse of the Pharaohs." The CT examination of King Tut is part of a five-year initiative called the Egyptian Mummy Project to image ...

3-D ultrasound scanner could guide robotic surgeries

...ers have shown that a three-dimensional ultrasound scanner they developed can successfully guide a surgical robot. The scanner could find application in various medical settings, according to the researchers. They said the scan...

New MRI technique quickly builds 3-D images of knees

... says. To capture an image, a magnetic resonance scanner commonly conducts hundreds to thousands of little "experiments," or encodings, that help to make up the big picture. Block's data-acquisition technique capitalizes on recent magnetic resonance hardware advances that, coupled with a novel way of maint...

Memory loss affects more of the brain than previously thought

Previous studies looking at structural changes alone have sho...

Oops! Researchers publish new findings on the brain's response to costly mistakes

...calize this response even more precisely. The fMRI scanner uses magnetic fields to create images based on blood flow, and can detect tiny changes in the rate of blood flow in and out of various areas of the brain. The more blood flowing to a specific area, the more active the cells in that area are ?and ther...
