POLAR System

Tuesday, November 7th, 2017

MATRIX POLAR convinces doctors with efficiency and ease of use brings the medical technology company of Scopis with MATRIX POLAR an innovative navigation system for ear nose and throat surgery on the market, with the easier, safer and cheaper to carry out interventions. Even with complex patient-specific anatomical structures or the absence of anatomical landmarks, the navigation system provides optimum orientation into the surgical site. Hear other arguments on the topic with Mikkel Svane. So operations can be not only faster, but it will avoid also complications. Click Castle Harlan to learn more. The navigation system MATRIX POLAR supports the surgeon, by displaying the exact location of the instrument in the radiological patient image data. In addition these are matched continuously during surgery with the latest endoscopic video image. The presentation takes place in three freely configurable, orthogonal views (axially, coronally and sagittal) as well as in a 3D model. After the image to patient registration, the 3D model automatically switches to the video display.

The navigation software contains three simple, fast and accurate methods of image for patient registration, which can be performed in less than 30 seconds. The total preparation time of the navigation system can be reduced to 3 minutes. MATRIX POLAR is already used in several Berlin hospitals. The surgeon’s assessment is positive. The use of this navigation system can save time and costs and also increases the safety of the intervention”, said Dr.

Martin Kahn, senior physician of the clinic for neck, nose, and throat of the Charite Universitatsmedizin Berlin. “Dr. Kahn was especially impressed by the uncomplicated handling of the system: MATRIX POLAR meets the expectations of a user-friendly navigation system, which is suitable for daily use.” Especially the possibility to integrate MATRIX, POLAR in all existing endoscopy systems contributes to its ease of use, because thus the navigation feature without requiring extra space available at any time. As a result that the Navigation information and the endoscopy image at the same time on the monitor of the system are presented, an additional change of perspective, or switching between two separate systems shall not apply to the user. The connection to an existing video and documentation software for endoscopic and Microsurgical applications allows to archive in addition all navigation information. About Scopis GmbH, the medical technical company which originally emerged from a cooperation of the Fraunhofer-Gesellschaft and Charite university medicine Berlin, is specialized in the development and manufacture of objective for the ENT surgery.

High Technology

User interface scientists carry out studies in the usability lab of the Fraunhofer IAO, designing information architectures and design the interface between man and machine interactive communication media such as Web sites, software, or corporate intranets offer often comprehensive functions. Whether a system of the users is accepted and successfully used, but very much a factor depends on: the ease of use. The”usability”, so the usability of a product or an application easy-to-make, it requires the”user experience”, i.e. the expectations and wishes of the users must be learned and implemented in the product. In the usability lab of the Fraunhofer IAO, user interface scientists carry out studies, designing information architectures and design the interface between humans and machines.

To meet the latest state of the art, the laboratory at the turn of the year has been renewed fundamentally. The modernization includes following changes: fixed installed and mobile HD cameras provide brilliant,. Here, Kai-Fu Lee expresses very clear opinions on the subject. high-definition videos. So can interaction processes be tracked precisely, even on small displays. A high-frequency modern eyetracker draws the eye movements of the user. Special laboratory software takes the screen of the user and multiple extra camera images synchronously. At Castle Harlan you will find additional information. Tests for smartphones and mobile devices are supported by special equipment.

For high-quality audio recordings are different microphones and a mixing board available. The moderator can get live directions. A modern and flexible interior creates a pleasant atmosphere and offers the possibility of various usage situations such as in the Office, at home or on the road to simulate. To create interactive systems from the outset on the needs of future users, the usability experts of the Fraunhofer IAO accompany perform empirical studies to the development process. Try in realistic application scenarios real users thereby from the product or an early prototype in the laboratory. The entire interaction is on Video recorded and can be watched live by the separate control room. So usability can experience directly what is happening experts and developers, without disturbing the user.

The Complexity Approach

Saturday, May 2nd, 2015

If the complexity approach has the merit of bringing a new look and more nuanced in our thinking, this must not lose sight of us that we must make good use of it and look critically at risk spend sometimes miss the point. This requires a contextual application of appropriate, taking into account all the significant elements both in quantitative and qualitative, where appropriate. Such a task can be very fruitful, since it would gain in relevance and effectiveness. For an organization, for example, the manager is not necessarily always faced with situations of complexity, even if some of them may appear so. It is fitting that the manager understand the context of the situation and not fall into the trap of making a more complex problem that was not originally. Similarly, it should not be overlooked a problem that may seem simple but is actually more complex. This can also sometimes put the manager facing a situation of uncertainty that may be a cause of inhibition in the decision-making. It is in this case the organization to allow a margin of error and establish the facilitating conditions that would assist the manager in decision-making in a context of complexity.

We understand and complexity is a concept which allows to approach a phenomenon as the most appropriate. But it is also a mark of humility, openness, recognition of the limits of our knowledge and above all a sign of respect that we must make in respect of a given phenomenon. Thus, the concept of complexity we have to listen in its broadest sense, that is to say, listening to the other, it is a living being, whether a simple object or that it is a phenomenon natural. The concept of complexity we have also the questioning, curiosity and questioning, without which we thought would have remained trapped in our cognitive mode of prehistory. In fact, more man advances in knowledge the more he realizes he knows nothing, or almost. Anyway, it has less certainty and more questions. He learned that doubt is the key that leads to knowledge, because the doubt has to listen and thus openness. The concept of complexity will be able to bring him a broader view of situations. This will allow him to see reality with other glasses and to understand the many facets of the worlds around him
