On the forefront of an emerging science

Humans have long wished to see beyond what our limited vision permits. For proof, consider the invention of microscopes, telescopes and satellites. Today at the ��Ѹ��Դ��߿�Ƭ of Lethbridge, researchers are using state-of-the-art digital imaging technologies to view even more areas – within the body and across the planet – that would otherwise be inaccessible to mortal eyes. Along the way, vast amounts of data are being collected.

"Solutions to the world's biggest problems can be resolved with high-quality, reliable data," says Dr. Daniel Weeks, the U of L's vice-president (research). "Our researchers are gathering, analyzing and making data more useful so important decisions can be made faster and more easily."

The emerging science of digital imaging is being pushed by researchers across disciplines at the ��Ѹ��Դ��߿�Ƭ of Lethbridge.

For example, using sensors to acquire information about the Earth's surface (a process called remote sensing) can help farmers evaluate the health of their crops. In medicine, similarly, magnetic resonance imaging, which produces 3-D images of soft tissue, can enable doctors to assess a patient's brain after a stroke.

For these reasons, and many more, imaging was named one of the top 20 greatest engineering achievements of the 20th century by the National Academy of Engineering in the United States. Indeed, imaging is effecting enormous change in multiple fields. In recent years, the U of L has attracted numerous international imaging-science researchers in such diverse disciplines as physics, astronomy, kinesiology, geography, neuroscience and new media. As a result, the ��Ѹ��Դ��߿�Ƭ identified imaging as a key area for growth.

There are many on-campus facilities dedicated to supporting imaging research at the U of L. They include two remote-sensing laboratories, a brain-imaging centre and a soon-to-be completed and unique-in-Canada facility for calibrating remote-sensing instruments. Also, the ��Ѹ��Դ��߿�Ƭ is home to a satellite-receiving station that is operated in conjunction with Iunctus Geomatics Corp., founded by U of L alumnus Ryan Johnson (BSc '98, MSc '00).

Two researchers benefiting from those facilities are Dr. Craig Coburn of the Department of Geography and Dr. Albert Cross of the Departments of Neuroscience, and Physics and Astronomy.

Coburn is finding new ways to solve problems with, and extract information from, remotely sensed data. He has built remote-sensing instruments for such clients as the U.S. Naval Research Laboratory and the U.S. Army Corps of Engineers. And while the official use of the instruments is classified, Coburn speculates their job may be to spot disturbances in soil. This data could indicate the presence of landmines, for example.

"Imaging is about more than pictures," says Coburn, reflecting broadly on the field. "These are scientific-grade research instruments floating in space and they can provide a lot of valuable information if we know how to render the image."

The same is true of neuroimaging instruments, says Cross. "Using functional magnetic resonance imaging (MRI), we can track activity in the brain and unravel how the brain is organized."

An MRI physicist, Cross is developing new, minimally invasive techniques for neuroimaging. Using lab rats, Cross is studying the efficacy of manganese as a way to produce contrast changes in regions of the brain that correspond to prior experiences during MRI scans.

Imaging science can effect tremendous change in many fields, Weeks believes. On that note, the ��Ѹ��Դ��߿�Ƭ plans to broaden the impact of its imaging science research. "We're reaching out to potential partners in China, India and Germany, for instance. By finding new collaborators and exploring new avenues of discovery together, we can further increase the ��Ѹ��Դ��߿�Ƭ's global footprint in this exciting area of investigation."

Extraterrestrial

Long before Star Trek popularized the phrase, "To boldly go where no man has gone before," humanity has been interested in the cosmos. But sending people deep into space is dangerous and expensive. Fortunately, extraterrestrial imaging enables us to find faraway stars, galaxies and planets, and puts the universe in closer reach.

Neuroimaging

We already have proof that the brain is a powerful tool. You do, after all, remember the location of your keys (most days). But in what areas of the brain does thinking actually happen? And how does the whole system work? By providing images of the brain as it goes about its business, neuroimaging offers important insights about the process of cognition.

Motion capture

Movement is something many of us take for granted. But researchers know there's more to human motion than heaving yourself out of bed, running around with a to-do list and then crashing on the couch. What are the subtle mechanics of motion? Knowing this information will advance our understanding of how bodies move, and will benefit everything from the fine arts to the field of kinesiology.

Atmospheric

The air that surrounds our planet may appear clear some days and a smoggy soup on others. But no matter the atmosphere's appearance, there's always a mix of gases up there. Some have little impact on our weather. Others, like carbon dioxide, are dramatically changing our climate. Atmospheric imaging researchers study the composition of the Earth's atmosphere and detect the trace gases that can be climatic game-changers.

Satellite

We've come a long way from the days of setting out on long expeditions to record the contours and features of the land. Today, we look above to satellites for a big-picture view of the planet. But small details are significant, too. For instance, what's happening on the Earth's surface in each region of the world? Satellite imaging enables us to see such phenomena as deforestation and the development of deserts.

Building strong academic and public institutions is fundamental to fostering innovation that will lead to a successful and sustainable technology sector.

As well, strong business communities and research hubs are required to create a viable technology economy to provide jobs for graduates and skilled professionals. In that regard, Lethbridge-based Iunctus Geomatics Corp. is leading the way.

The company, which was founded by U of L alumnus Ryan Johnson (BSc '98, MSc '00) and employs a significant number of U of L graduates, was recently an Alberta Science and Technology (ASTech) winner in the Outstanding Achievement in Applied Technology and Innovation category.

Since the company was founded in 2000, Iunctus (a Latin mathematical term meaning "to bring together") has developed leading remote sensing products. Among them is the TerraEngine, which facilitates the storage and transmission of large files of digital imagery over the Internet.

Additionally, their remote sensing data is used to create geographical maps and other data for industries including agriculture, disaster management, forestry, telecommunications planning and oil exploration.

Iunctus has two sister companies, BlackBridge, a data centre company, and PrioraNet Canada, a joint venture with the Swedish Space Corporation which operates ground stations.

The company currently employs more than 50 people who support the satellite operations of the German Space Agency (DLR), French Space Agency (CNES), as well as manage all the data over North America for SPOT Image. Iunctus supports the operational requirements of clients across Canada in all segments of land management from commercial to government.

Iunctus is also a partner with the ��Ѹ��Դ��߿�Ƭ of Lethbridge in a separate business called the Alberta Terrestrial Imaging Corp. (ATIC) that focuses on developing more commercial applications for remote sensing technologies.

True to its name, Iunctus is literally bringing together the geomatics industry in Lethbridge. Iunctus recently invested $1 million into a partnership with the City of Lethbridge to sponsor tecconnect – an Alberta centre for new commerce in a new facility designed to attract, incubate and develop technology companies through commercialization of their products and services.

"We hope to make a big difference in the community by attracting other technology businesses to our city," says Johnson, the Iunctus president. "We are helping young entrepreneurs by building a hub for technology companies to grow and stay in Lethbridge."
