We take a look at some point-of-care applications in our Topic of the Month.
01/04/2021For surgeons, nothing is more important than intimate knowledge and a spatial understanding of their operating field. Yet even three-dimensional imaging methods only provide limited assistance because the data is viewed on two-dimensional screens. When it comes to surgical planning or medical education, Mixed and Virtual Reality foster a better spatial understanding of the human body.
01/04/2021The job of surgeons starts long before they step into the operating room. They must use two-dimensional MRI or CT scans to plan the surgical steps on a three-dimensional patient, relying on their experience, skill, and spatial sense. Using mixed reality (MR) to view human anatomical models allows for better visualization and navigation.
01/04/2021Surgeons do not only have to gather theoretical knowledge and practice to perform successful interventions. They also need a good visual thinking and have to know the anatomical characteristics of each individual patient. Some of these tasks will become easier when Virtual and Mixed Reality bring three-dimensional, digital models into their profession.
08/10/2020Surgery can be very strenuous for a surgeon, as he often has to bend over the patient in a rigid position for hours.

24/08/2020For the annual MEDICA trade fair, companies from all over the world assemble in Düsseldorf. The Israel Export Institute has been a part of it for the last couple of years. They present medical devices and digital innovations from different Israeli companies at their joint booth.
10/08/2020This is how a conventional ultrasound scan works: patients lie down on a table next to the ultrasound machine. A doctor uses a probe to scan the part of the body in question, while he or she looks at the pictures on a monitor. In other words, the physician either focuses on his/her hand on the patient or the monitor. The Fraunhofer IGD wants to change this process as part of the "sonAR" project.
02/06/2020After a stroke, a patient’s life depends on getting acute care at a hospital. Vital monitoring systems ensure safe and effective treatment. An innovative tomographic imaging system is designed to help prevent the patient’s risky journey to radiology and to enable bedside monitoring of cerebral blood flow.
02/06/2020Stroke can affect anyone – older as well as younger people. The minutes after the stroke determine whether disability or death is the result. Only if acute care, inpatient treatment and rehabilitation are carried out in a targeted and effective manner, the chances are greater that only minor damage remains or that impairments even recede.
02/06/2020"Time is brain!" – a fundamental rule in stroke care because time is of the essence when brain regions are undersupplied with oxygen and glucose. If circulation is not restored quickly, brain damage can be permanent. However, the key point here is not just to "be fast", but also to "use the time to treat stroke effectively".
08/04/2020The University Hospital Bonn has recently introduced an ultrasound device that's small enough to fit in your coat pocket. It's ready to use once you have connected it to a tablet or smartphone. The portable system makes bedside physical exams possible. The device primarily benefits students as it allows them to combine basic knowledge and clinical application.
09/03/2020Treatment of a heart attack or stroke caused by vascular occlusion must be prompt to prevent further damage to vital tissue.

AI might perform this task in the future.
22/01/2020Patients have to undergo a gastroscopy to rule out gastrointestinal conditions. Many dread this procedure since a thin, flexible tube is being pushed through the esophagus and stomach. Ovesco Endoscopy AG has teamed up with other project partners in the nuEndo research project to develop a capsule endoscopy device that is tiny, easy to swallow and makes the test more comfortable for the patient.
01/01/2020Surgery is required if you need an artificial joint. Patients and doctors must select the type of surgery that’s best suited and choose between robot-assisted, traditional or minimally invasive surgical approaches. Post-operative risks should be kept to a minimum, while benefits should outweigh any possible complications.
01/01/2020Joints can suddenly or gradually deteriorate and lose their natural strength, whether it’s due to accidents, diseases or simple wear and tear. In some of these cases, implants of artificial joints – endoprostheses - can help. As a joint replacement, they are designed to stay in the body for as long as needed and as such improve the patient’s quality of life and mobility.
14/11/2019Acute respiratory distress syndrome (ARDS) is a life-threatening illness in which the lungs are severely damaged.

02/09/2019In modern medicine, especially in the field of imaging, huge amounts of data are produced – so much that radiologists can hardly keep up with diagnosing the images. Artificial Intelligence could be the solution to this problem. But how exactly can it help in this task? How can man and machine work together? And what else will be possible in the future with the support of intelligent systems?
02/09/2019More patients, more examinations, more CT images – in radiology there is too much work for too few physicians. CT scans are evaluated in the shortest possible time, which leads to anomalies being overlooked. Artificial intelligence, on the other hand, works with constant speed and performance, which is why radiological routine increasingly relies on its support.
02/09/2019Radiology is a field that produces large volumes of data, which can no longer be managed without the help of intelligent systems. This is especially true when it comes to the interpretation of medical images. While this takes physicians years of training and experience, several hours of work and the highest level of concentration, AI only requires a few seconds to accomplish the same task.
02/09/2019Artificial intelligence is no longer a dream of the future in medicine. Many studies and initial application examples show that it sometimes achieves better results than human physicians. At Jena University Hospital, the work with AI is already lived practice. It is the first institution in the world to use algorithms in radiological routine to reconstruct CT images.

08/08/2019After their tumor has been removed, some patients have to return to the hospital to undergo surgery again. That's because the tumor was not precisely identified and was subsequently not completely removed. That's both an ethical and financial dilemma. A new surgery-adjacent procedure is designed to rapidly and accurately detect tumors.
22/07/2019Modern imaging opens news doors to surgeries. Yet it also poses major problems for surgeons: They use two-dimensional images to navigate through a three-dimensional surgical environment, while they continuously have to switch their focus back and forth between the images and the patient. Now help is on the way in the form of interactive 3D projections and mixed reality (MR).
24/06/2019Improving technology transfer from research to industry and driving robotics development - that's the idea behind the KUKA Innovation Award. This year’s topic is "Healthy Living".

11/06/2019Epilepsy patients are currently treated with either medication or surgical options. The aim is to remove the distinct regions of the brain that cause epileptic seizures. Laser ablation for epilepsy is a new, catheter-based surgical procedure that is now also available in Europe, preventing patients from having to undergo open brain surgery.
23/04/2019It's noisy, tight and scary - that's how children feel about a magnetic resonance imaging (MRI) machine. Because they are scared, they are often too fidgety and anxious during the procedure, causing the images to blur or the scan to be stopped. Researchers have now developed a VR app called Pingunauten Trainer that’s designed to gently prepare the little patients for MRI scans.
08/04/2019Cardiac arrhythmia is a group of conditions where nerve cells trigger uncontrolled contractions of the heart muscle. They are treated with either medicine or catheter ablation of the tissue. In an interdisciplinary collaboration, cardiologists and radiotherapists took a different approach and used high-precision radiation therapy to treat a patient for whom the other options proved unfeasible.
01/04/2019A surgery already begins before the patient is lying on the operating table – namely with the planning. For example, if brain surgery is imminent, the brain must first be mapped. This makes the activity level of certain brain areas visible. Functional magnetic resonance imaging makes this possible.
01/04/2019All information from our body and the environment converges in our brain and is transformed into reactions in milliseconds. It is essential for medicine and research to know what our switching centre looks like. Functional methods are used to observe it more closely during work.
01/04/2019Our brain is the command center of our body. This is where all information and impressions are collected and converted into responses and movements. Modern imaging techniques offer physicians and researchers unique insights into the actions of the human central nervous system. The functional imaging technique allows them to watch our brain in action.
01/04/2019In an ischaemic stroke, rapid treatment is essential. In this moment good imaging data is particularly important to enable doctors to make the best possible decision for therapy. Modern CT scanners are increasingly being used to assess stroke patients because they can show the blood flow to the brain over time.
01/03/2019People suffering from lung disease temporarily need ventilator support because they are unable to breathe naturally. Mechanical ventilation is designed to ensure the survival of these patients. The goal is to adapt the ventilator settings and tailor them the patient's specific needs and prevent lung tissue damage.
25/01/2019CT scan, MRI or X-ray: All these methods allow doctors to see inside the body - including inside the lungs - and make a diagnosis. The clinic for Nuclear Medicine at the RWTH Aachen University Hospital uses a state-of-the-art gamma camera that combines SPECT and CT.
19/12/2018Continuous monitoring is an essential process with every disease. In the case of eye disorders, frequent retina measurements can facilitate early detection of deterioration to quickly initiate intervention. This calls for comprehensive care settings, easy ways to take measurements and prompt results. However, in reality, this is rarely the case.
14/11/2018Whether CT, MRT, X-rays or ultrasound – imaging methods provide insights into the human body and are irreplaceable for diagnostics. They are part of everyday hospital life since a long time, but what is currently happening in this field? We took a look – at MEDICA 2018.
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.
23/07/2018Every year, more than 250,000 patients worldwide receive heart valve implants. Children require repeated replacement surgery because their bodies are still growing, the prosthetic heart valves are not. Regenerative heart valves solve this problem. Until now, we have only been able to monitor how these living implants develop in the body after the fact. Computer models now make this predictable.
22/06/2018A drop of blood provides a lot of valuable information. However, it takes several hours to analyze the blood of a patient and make a diagnosis. This takes away a lot of time that's crucial for treatment. A new method intends to considerably speed up this process by testing the cells in the blood in terms of their deformability and immune response.
21/06/2018Biomechanical measuring systems are used in orthopedics to diagnose and treat misalignments and diseases. The Velamed Company uses its high-tech solutions to measure biomechanical parameters that enable a holistic analysis of human movement and posture. We took a closer look at how this works.
17/05/2018Ventricular fibrillation is a life-threatening condition that occurs when the heart muscle exhibits a rapid, erratic beat. The cause might be a circulatory system disease or heart attack. Researchers in Göttingen are now developing an ultrasound technique to get to the bottom of ventricular fibrillation and cardiac arrhythmias and facilitate better treatment options.
08/03/2018Automation makes work life easier in many ways but is it also a solution for analyzing medical images? Is a computer actually reliable enough to assist in the medical decision making process? Researchers in Landshut examine how machine learning algorithms can work more reliably and support radiologists.
06/03/2018With the help of surgical navigation systems, prostheses or implants can be better inserted. During the procedure, surgeons can see exactly where they need to operate on a screen. Just like a navigation system in the car, navigation in the OR guides you precisely to your destination. At the Uniklinik RWTH Aachen we can find out what advantages this has for physicians and patients.
08/02/2018When body tissue is reconnected during a tumor operation in the gastrointestinal tract, surgeons need information about the current state of these so-called anastomoses. The new, non-invasive hyperspectral imaging technology now makes it possible to measure the crucial parameters during surgery and thereby increase surgical precision.
