Virtual reality that allows doctors to visualise the heart in three dimensions could help in the diagnosis of heart conditions. A pilot study published today in the open access journal Cardiovascular Ultrasound reveals that doctors can diagnose heart conditions quickly and easily from virtual three-dimensional animated images or ’holograms’ of the heart. Three-dimensional (3D) holograms allow doctors to ’dive’ into the beating heart and see interior parts of the organ.
Annemien van den Bosch and colleagues, from Erasmus MC University Medical Center Rotterdam in The Netherlands, projected ultrasound-generated 3D images of hearts (echocardiograms) in a specially designed four-walled room called the I-Space. In the I-Space, images are projected on three of the walls and the floor, which results in an animated hologram floating in space in front of the viewers. The viewers wear a pair of glasses with polarising lenses allowing them to see the hologram with depth.
Van den Bosch et al. asked ten heart specialists to analyse the holograms of patients with a heart defect that affects the shape of an inside part the heart, and of patients with a healthy heart. The doctors learnt how to use the equipment and were able to virtually ’cut through’ the heart to see inside, using a virtual pointer, within ten minutes. The ten doctors could all distinguish healthy from unhealthy hearts and make the correct diagnosis within only ten minutes.

3D images of cancer cells in the body: Medical physicists from Halle present new method

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
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...
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...
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...
