Is it a heart attack or something else? How artificial intelligence can support diagnostics

22.07.2022

Chest pain, shortness of breath, a brief loss of consciousness – warning signs that suggest a heart attack. But it might also be Takotsubo syndrome, also known as stress cardiomyopathy or broken heart syndrome with symptoms that resemble a heart attack. Yet it is of utmost importance to differentiate between the two conditions to initiate the right treatment.

Sonography training – Inexpensive models from the 3D printer

23.05.2022

Many medical disciplines rely on the tenet "Practice makes perfect". Sonography diagnostics is one of them. Unfortunately, constant training can be difficult, as patients with specific diseases are not present at a hospital all the time. The University Hospital Bonn is creating a solution for this problem: 3D printed models of joints and arteries are used in training.

Point-of-care ultrasound helps in emergency diagnosis

01.06.2021

Medical emergencies require quick action and prompt decisions: Point-of-care ultrasound (POCUS) is a valuable diagnostic tool available to the emergency physician. Rather than relying on his/her gut feeling, the device answers specific clinical questions that narrow differentials. The question is, in which settings does POCUS deliver the biggest benefits?

Faster treatment thanks to point-of-care diagnostics – in emergencies and beyond

01.06.2021

Making an informed and immediate treatment decision near or at the patient’s bedside – point-of-care testing (also known as POCT) makes this possible. Unlike stationary devices, special exam rooms or other service infrastructure, POC diagnostic devices offer a multitude of benefits including more flexibility, faster results, and lower costs.

Broader perspective: how Mixed and Virtual Reality transform surgery

01.04.2021

For 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.

Wearables: skin patch as an all-in-one health monitor

17.02.2021

Engineers at the University of California San Diego have developed a soft, stretchy skin patch that can be worn on the neck to continuously track blood pressure and heart rate while measuring the wearer's levels of glucose as well as lactate, alcohol or caffeine. It is the first wearable device that monitors cardiovascular signals and multiple biochemical levels in the human body at the same time.

Augmented reality ultrasound: putting the focus on patients

10.08.2020

This 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.

Endoprostheses - Ultrasound to detect loosening?

27.02.2019

Many patients suffering from arthrosis or other kinds of damage in the hip joint need an endoprosthesis at some point. However, this prosthesis can loosen again after some time, so that it must be replaced. In order to delay this replacement surgery for as long as possible, the TH Mittelhessen University of Applied Sciences develops a new diagnostic method.
