01/10/2018A look inside the lungs is a time-consuming process. To identify the boundaries of the respiratory organ from surrounding other organs, tissues, and structures requires between 200 and 500 computed tomographic images and subsequent manual markings – an elaborate process that can take up to six hours. An optimized computer program is now able to do this in only a few seconds.
01/10/2018Thanks to various imaging supplies, it is possible to make the inside of the body accessible for diagnostics, research and treatment. The lung, one of the most important human organs for survival, is also examined in this way. In our Topic of the Month, we looked at how doctors are getting a closer look at the lung, how the procedures differ, and which ones will be available in the near future.
01/10/2018Lung cancer is one of the most common and deadliest cancers. The symptoms tend to be non-specific, often causing its detection to be too late. Currently, there is no comprehensive screening. This could change with the use of low-dose CT scans. It should be noted that this is not just an issue of technical feasibility. A screening test must also make sense from a health policy perspective.
03/09/2018In a Smart Hospital, all devices are designed to be connected and integrated, thus increasing efficiency and reducing time loss – at least, that is how things are meant to work in theory. In reality, there are still countless vendor-specific point solutions that cannot be integrated. That's why there is a need for solutions that bridge the gap between the different applications and formats.
08/08/2018Some solutions are simple, though not necessarily obvious. The WAKE-UP study, which included 70 participating European stroke centers, has now studied a relatively simple procedure to manage the acute care of stroke patients and avoid potential long-term effects. Best of all, it is available wherever MRI is offered.
01/08/2018For years, medicine has been exploring AI techniques aimed at easing physician workload. While computers may not have the medical expertise and skills obtained through years of study, they can recognize patterns and specific features in datasets and draw deductions.
23/07/2018Every year, more than 250,000 patients worldwide receive heart valve implants.
