How advancing technologies and changing market dynamics are creating new services, products and more importantly a platform and virtual culture to allow innovation.

innovation and disruption
Innovation and disruption

The development of new technologies may arise from existing technologies in one field applied to a new field or the convergence of several technologies to create a new technology.

magnetic resonance imaging
Magnetic resonance imaging

Magnetic resonance of nuclei discovered in the 1950s

Explosive growth in the study of Molecular structure in chemistry and biochemistry

In the 1970s Paul Lauterbur discovered how to spatially localize magnetic resonance signal

“The use of telecommunications and information technologies in order to provide clinical health care at a distance.”

early adaptors
Early Adaptors

African villagers used smoke signals to warn people to stay away from villages infected with serious diseases.

Australians used two-way radio’s in the early 1900’s to communicate to flying medical services.

Communications Technology

Similarly the advent of the Internet age and personal computers has redefined Society in the 21st century.

Information is now freely available to remote regions with social networking including oral and video communications transmitted across the globe and often independent of international borders.

communications and medicine
Communications and Medicine

The ability to provide medical services to ever growing numbers of people, in wider and more remote locations, with greater knowledge based sophistication of services is one of the challenges of our Era.


Teleradiology is greater than 50% of all telemedicine

tele something

Through a technology called telepresence, it creates the illusion that students miles apart are in the same classroom.

Interactive television isn't new. Schools have been doing distance learning for years. But the Ojibwe language telepresence classroom at Deer River High School goes well beyond a simple TV monitor and a camera.

At a pair of long desks, teacher Gerald White and eight high school students recently recited Ojibwe phrases. They faced three huge, high-definition screens at the front of the room. In an identical classroom 25 miles away in Remer, Minn., a classmate was in a room with the same furniture, tan walls and carpet. She also recited Ojibwe phrases, giving the impression that they were all a few feet from each other.

White is the only Ojibwe language teacher within the seven districts that comprise the Itasca Area Schools Collaborative. He said telepresence technology makes him a more effective teacher.

visions of the future
Visions of the future

The environment of telemedicine is moving from its infancy to being a more mature and important component of medical service.

The instrumental components that have allowed the initiation of telemedicine will inevitably expand and become more sophisticated. The continued technological, organizational, and political components that will foster telemedicine will be complex and likely evolving over time.

To understand, anticipate, or envisioning of the future requires a look at where we have been and where we are today.
