New tool enhances view of muscles

24.01.2012
Simon Fraser University associate professor James Wakeling is adding to the arsenal of increasingly sophisticated medical imaging tools with a new signal-processing method for viewing muscle activation details that have never been seen before.

Fascinated with the mechanics of muscle movement in people and animals, Wakeling has developed a novel method using ultrasound imaging, 3D motion-capture technology and proprietary data-processing software to scan and capture 3D maps of the muscle structure — in just 90 seconds.

It’s a medical-imaging breakthrough because previous methods took 15 minutes to do the job—far too long to ask people to hold a muscle contraction.

The key to the breakthrough is the way the software processes the data, says Wakeling, who teaches in SFU’s department of Biomedical Physiology and Kinesiology. He developed the software with graduate student Manku Rana.

“Now, we can get people to do muscle contractions and we can actually see how the internal structure of the muscle changes,” he says.

Wakeling’s goal is to improve the muscle models used in musculoskeletal simulation software that predicts how people move and the forces on their joints.

Current packages are missing important information about muscle contraction, such as how the muscle shape changes, how it bulges, or how the internal muscle fibres become more curved—all details that Wakeling’s technology can capture.

Wakeling hopes his research will ultimately lead to new software programs for predicting the outcome of orthopaedic surgeries such as tendon-transfers for treating conditions like cerebral palsy in children.

“We’re poised to start making new observations and insights,” he says, “and to do new experiments that haven’t been possible before.”

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
