About the Biomedical electromagnetics research area

Within the research area of Biomedical electromagnetics, new and more effective medical methods and systems are developed for diagnostics and treatment of certain illnesses. Stroke diagnostics, breast cancer detection, microwave tumor treatment and localization of epileptic brain activity are a few examples of applications where Chalmers pursue research using electromagnetics. Researchers also carry out a more general, fundamental type of research with the aim to discover new methods and applications.
 
The goal is to generate more effective tools in the battle against some of society’s most common diseases, increasing the quality of life and survival of patients whilst minimizing total care costs.
 
The research focuses mainly on the development of new methods for signal processing, and developing antenna systems and measuring equipment. Another cornerstone in the process involves numerical modeling and simulation of systems and algorithms under development. Some projects also include the construction of complete prototype systems for clinical tests.
 
The activity encompasses a great part of the electromagnetic spectrum, from low frequencies up to the THz area, with special focus on microwaves. The telecom industry component development has been very useful for the research within electromagnetics with medical applications. Signal processing and the development of algorithms often demand heavy calculations and benefits from the constant and fast IT development.
 
A great part of the research activity is pursued within the CHASE and MedTech West centres and a VR financed framework program.

Research projects

This is a project on the development of systems for hyperthermia treatment of deep-seated cancerous tumors, based on the microwave technique. The Chalmers research team concentrates especially on tumors in the neck area, and brain tumors in children...
 
This project aims to improve currently inadequate diagnostics for correct and anatomically precise localization of the epileptic focus, in order to enable surgical therapy. The reason is that anti-epileptic drugs frequently fail to successfully control epileptic seizures...
 
Chalmers are developing a new method for breast cancer diagnostics based on microwave tomography. This method has the potential of providing more accurate diagnosis than that of X-ray based mammography, which is the main technique today...
 
This project aims to further develop the hardware in microwave based measuring equipment, so that future equipment can be built in a compact and economical way whilst retaining measurement accuracy. The long term goal could be described as “microwave tomography on a chip”...
 
This project investigates how Terahertz frequencies could be used in future medical applications. Compared to visible light, Terahertz waves are affected by different material properties. This means that something which is difficult to visualize with light could become much clearer in the Terahertz area...
 
A stroke patient with a blood clot in the brain needs treatment within four hours in order not to decease or suffer severe disability. Therefore, the Chalmers research team are now developing an instrument for faster stroke diagnostics...
 
This project aims at developing a sensor array of antennas capable of microwave tomography for pharmaceutical processes, together with a post-processing algorithm for data analysis...
 
 
> Electromagnetic Fields in Welding; EMFWELD
​The European fabrication industry is required to ensure that workers exposure to EMF (Electro Magnetic Fields) is below the levels set out by the forthcoming European Commission’s...
 
> Development of Procedures and Instrumentation for Demonstration of Worker´s EM Safety 
WEMS is a EUREKA project with partners from Sweden, Switzerland, Belgium and Austria. There will be a EU-directive on workers exposure to electromagnetic fields demanding that the employers shall show compliance with the limits in the directive...
