First Images from Medical Beamline at Canadian Light Source

29.12.2008
A University of Saskatchewan (U of S)-led research team at the Canadian Light Source (CLS) synchrotron has received an early Christmas present. After several years of research, construction and testing, the unique-in-North-America BioMedical Imaging and Therapy facility (BMIT) captured its first X-ray images.

“Our entire team was just thrilled with what we saw – the images we’re getting on BMIT are as good as any I’ve gotten at any other synchrotron. That’s quite an achievement given that we had our first X-rays down the beamline less than a month ago,” said Dean Chapman, U of S Canada Research Chair in X-ray Imaging and BMIT team leader.

“The BMIT team is profoundly grateful to the staff of the CLS who have worked extremely hard over the past several years to bring this facility to fruition. In the coming months, we’ll be working closely with the CLS, the U of S and the Saskatoon Health Region to build the local, national and international research capacity of this world-class facility.”

“This is great news, both for the BMIT team and the Canadian Light Source,” said CLS Executive Director Josef Hormes. “BMIT is such an important facility, not just for the CLS but for the future investigation and treatment of diseases that have an impact on Canadians and people around the world.”

The X-ray images of a mouse were taken using a technique called diffraction-enhanced imaging (DEI), co-discovered by Chapman, U of S professor and former CLS Executive Director William Thomlinson, and U.S. researcher Zhong Zhong. The imaging team included Chapman, Thomlinson, CLS staff scientist Tomasz Wysokinski, U of S researcher David Cooper, graduate students Brian Bewer and Ying Zhu, and Dr. Sheldon Wiebe with the Saskatoon Health Region.

DEI uses the unique properties of synchrotron X-rays to produce images of soft tissues such as muscle, organs and tumours that do not readily absorb X-rays, making them cloudy or invisible to conventional X-ray radiographs and mammograms. For example, the mouse’s lungs are clearly visible in the DEI image, but only appear as a faint blur in the conventional absorption image.

DEI imaging is proving to be a valuable tool in visualizing cancer, imaging bone cartilage and understanding the structure and function of reproductive organs. Other techniques planned for development at BMIT include the delivery of precise beams of high energy X-rays for the treatment of cancer.

Under construction since fall 2005, BMIT is the only facility of its kind in North America and one of a handful in the world. The $17-million lab, consisting of two beamlines and support systems, will be complete in 2009. BMIT will be capable of imaging and therapy research involving plants and animals of all sizes – from hamsters to horses – and one day humans. The project is the result of an international collaboration of researchers from Canada, the U.S., Australia, France and Italy.

The Canadian Light Source is Canada’s national centre for synchrotron research. Located at the University of Saskatchewan in Saskatoon, the CLS is a powerful tool for academic and industrial research in a wide variety of areas including environmental science, natural resources and energy, health and life sciences, and information and communications technology. CLS operations are funded by the Government of Canada, NSERC, NRC, CIHR, the Government of Saskatchewan and the University of Saskatchewan.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
