Feeling a heartbeat via a computer

30.05.2007
The dynamics of a beating heart, the turbulence surrounding the fuselage of an airplane, or the field of forces inside a molecule. All of these things can be felt, not only seen, with a new visualization technology developed at Linköping University in Sweden.

Today's powerful computers have opened previously unimagined possibilities regarding the presentation and analysis of scientific data. Volume data, in particular-such as three-dimensional computer tomographies of the human body-can contain incredible amounts of information. When such data are to be analyzed, it can be an advantage to be able to use to more senses than sight alone.

Karljohan Lundin Palmerius at the Division for Visual Information Technology and Applications.

has developed methods to explore volume data using the sense of touch a branch of science that is often called haptics. He describes his pioneering work in a dissertation titled Direct Volume Haptics for Visualization.

Thanks to new computational algorithms, three-dimensional forms can be freely studied and perceived in a manner natural to the user, who works at a computer screen with a sort of touch tool. The most common type is constructed as an industrial robot in which miniature electric motors provide feedback to the hand.

"Different equations are needed for different applications. I am the first researcher to present the dynamic events of a beating heart in a real patient," says Karljohan Lundin Palmerius.

His Methods can be used to provide a better basis for diagnosis, but also for simulations for doctors to practice on a patient who will then be operated on in reality.

The medical data he works with come from the Center for Medical Image Science and Visualization (CMIV) at Linköping University. From SAAB he has been given access to data from the development of the unmanned airplane Shark and has created a virtual wind tunnel where the constructor can feel how the airstreams move around the fuselage.

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
