PhD student position in microwave hyperthermia at Chalmers

At the Department of Signals and Systems, we conduct world-leading research in biomedical engineering, antennas, signal processing,control, automation, mechatronics and communication systems. Our research deals to a large extent with the modeling and development of efficient systems for extracting and processing information. Systems our researchers deal with include for instance e-Health, hearing aids, robotics, power chains, and mobile telephony.

The department has about 120 employees, divided into three research divisions and one administrative unit. A majority of our activities are gathered at campus Johanneberg, except for some research in medical engineering which is done at Sahlgrenska and an education unit at campus Lindholmen. The department offers more than 70 courses, of which are most included in the Masters Programs; ”Biomedical Engineering”, ”Systems, Control and Mechatronics”, and ”Communication Engineering”.

Information about the division

The PhD-position is with the Biomedical electromagnetics research group. The focuses of this group is on the development of new and more effective medical methods and systems 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.  The main activity in the development towards these applications involves mainly, signal processing methods, antenna systems design and design of measurement equipment. Construction of complete prototype systems for clinical tests is a key goal in the projects.

Job description

The goal of the Chalmers hyperthermia project is to develop and perform clinical evaluation of a new applicator for treatment of cancer tumors in the head and neck region. Within the frame of the project you will explore a new approach for safe and effective delivery of the focused heating to the tumor. In particular, you will work on a novel treatment planning method which allows for dynamic steering. Its focusing core component relies on the time-reversal characteristics of electromagnetic waves. An integral part of this aim is a method for determining patient-specific parameters for thermal modeling. In short, you will work on a careful modeling of temperature distribution in a human body, which is the first step towards a clinically viable hyperthermia technology. This project will attempt to answer fundamental questions about the suitability of time-reversal approach for hyperthermia treatment planning.
The main objectives of the project are:

• Improvement the current State-of-the-Art of hyperthemia treatment planning.
• Enhancement of the temperature modeling techniques.

The majority of your working time is devoted to your own research studies. As a PhD student you are expected to develop your own ideas and communicate scientific results orally as well as in written form. In addition, the position will normally include 20% departmental work, mostly teaching duties.

The employment is limited to a maximum of five years.

Project background

Microwave hyperthermia is presently used as an adjuvant to the radiation therapy in the treatment of certain types of cancers. The goal of hyperthermia treatment is to raise the temperature of a localized cancerous tumor to 41 – 45 ºC for an extended period of time while keeping the energy deposition in healthy surrounding tissues under control. The most widely used approach for providing the deep hyperthermia is to use an array of antennas placed in a circumferential array around the patient. The wave interference, i.e heating of certain part of the body, can be driven inside the hyperthermia applicator by changing the amplitude and phase at the feed-points of the antennas. These can be obtained by optimization techniques during the treatment planning phase.


The applicant should have a Master of Science degree in Electrical Engineering or Engineering Physics or similar. Very good knowledge in electromagnetics and computer programing is required. Knowledge in computational electromagnetics is considered a merit. You should be a good team player and have an ability to take initiative. Very good communication skills in english, both written and spoken, is a requirement. Many courses at our bachelor programs are taught in Swedish, therefore good knowledge in the swedish language is considered as a merit.
