New clinical study demonstrates that the microwave helmet “Strokefinder” can be used for a rapid detection of intracranial bleeding in traumatic brain injuries

A recently published scientific paper shows that health care professionals get vital information and can quickly decide on appropriate treatment if patients are examined using a microwave helmet. The study demonstrates a new health care application for microwave measurements. Previously, microwave measurements have been used to distinguish stroke caused by bleeding in the brain from stroke caused by cloth. The new study shows that the technology also applies to patients affected by traumatic brain injury, which is the most common cause of death and disability among young people. This type of injuries are often caused by traffic accidents, assaults or falls. An estimated 10 million people are affected annually by traumatic brain injuries.

 

 

 

MikaelPersson_150W- Microwave technology has the potential to revolutionize medical diagnostics by enabling faster, more flexible and more cost-effective care, says Mikael Persson, professor of biomedical engineering at MedTech West and Chalmers University of Technology.  In many parts of the world microwave measurements systems can become a complement to CT scans and other imaging systems, which are often missing or have long waiting lists.”

 

 

 

 

 

 

- It is challenging to develop a new clinical methodology, from early tests to a device for clinical use in a hyperacute clinical environment where routine care of patients cannot be delayed. It requires a close collaboration between technical and medical professionals which has been supported by MedTech West, a western Sweden based organization for med-tech research & development driven by clinical need, says Mikael Elam, professor of clinical neurophysiology at MedTech West, the Sahlgrenska Academy and the Sahlgrenska University Hospital.

Facts about microwave measurements
A microwave helmet is placed on the patient's head and the brain tissue is examined with the aid of microwave radiation. The system consists of three parts: a helmet-like antenna system that is put on the patient's head, a microwave unit and a computer that is used to control the equipment, data acquisition and signal processing. Individual antennas in system transmit, in sequence, a weak microwave signals through the brain, while the other receiving antennas measure the reflected signals. Distinct structures and substances in the brain affect the microwave scattering and reflections in different ways and the received signals provides a complex pattern, as interpreted by using advanced algorithms.
