Innovations in medicine and bio-electromagnetics with Tilmann Wittig.

A few weeks ago, we published an introduction to the exciting world of bio-electromagnetic simulation. This highly specialized area of EM simulation boasts some of the most fascinating real world applications for EM simulation. Principal Engineer and Market Coordinator for bio-EM, Tilmann Wittig shares some of the innovations he is most interested in right now. Read on to see how EM simulation can help develop solutions for cancer treatment and detection, diabetes, head injuries, and more.

What in Bio-EM is most interesting for you right now?
The medical world is definitely the most challenging one because we need to see inside the body so,
in a mobile phone, the bio-EM is a parasitic side effect. We need to be careful of it, it’s important, but it’s not very fascinating but everything inside the body is much more fascinating.
I'm interested in all these tiny implants, which hopefully in the future may revolutionize our medical approaches. There’s research now into improving the pacemaker. The classic pacemaker is about 5x5cm wide, and 80% of it is the battery because it needs to last a long time because replacement requires invasive surgery. So why not use a more clever approach, like wireless charging and controlling and programming them from the outside? So, we have some customers who are looking at a pacemaker that’s  5x5x5mm, incredibly small. That means it can be put in laparoscopically which is minimally invasive and when it’s in it can be fully controlled from the outside. For that, you could have a wearable antenna that is both controlling the pacemaker and charging it, That could mean that hopefully in the future, getting a pacemaker is much less of a big deal than it is nowadays.

The second topic I find quite interesting is imaging because we want to be able to see what the body looks like on the inside. We need to be aware that 80-90% of images done of the human body are done by X-ray, which is what’s called “ionizing radiation” and that means it has a lot of power, which is good because it allows us to see inside a body, but it has so much power that could potentially crack our DNA. If that happens, if our DNA is cracked, we are lucky if the cell just dies, but if we are unlucky, it turns into a cancer cell. Today we rely on the use of x-rays, including CT (computer tomography) and mammography. CT is basically a three-dimensional x-ray, which means the dose is even higher, something like 50x the dose of radiation from a normal x-ray. While the levels are still low, there is still a risk of cancer, so researchers are trying to get away from x-ray for this reason.
Modeling Temperature Effects of RF Thermoablation in a
 Human Liver

Are there better, smarter ways to get the same images without putting patients at risk of DNA corruption and cancer? 
Microwave radiation is the answer to that, and we already have microwave imaging in MRI and that’s quite established. There are also other ways that researchers and scientists are developing using the same concept you have in a radar antenna to see into the body. There are research groups working on this by putting an array of 20-50 antennas on different parts of the body and those antennas are sending and receiving signals and from those signals, they try to analyze how it might look inside. The two main applications for that are breast cancer, so any kind of tissue abnormalities and also brain damage.
So, let’s say someone has an accident. It’s very difficult to know what’s wrong with the brain,  whether there is bleeding for example. The dream for the future is to have a helmet with one of these arrays, and you send out these microwave imaging signals and within 20 seconds you can get an answer, everything is fine, or there’s bleeding and the person needs immediate care. It’s common that people with head injuries can show no symptoms, if someone is coherent and speaking the people around them may think nothing is wrong with them, so this kind of quick and easy test can save lives.

CST recently awarded the 2017 University Award for a paper detailing this innovative method of intracranial hemorrhage detection. Read it here!

Treatment is the third area of interest, and there is a lot of innovation happening there. For example, we have an application note on thermal ablation, in which a diode is inserted into a cancerous tumor and it’s heated up to kill those cancer cells. That’s pretty amazing, but now there is an idea to do this non-invasively with just antennas. That works by giving the patient heat sensitive drugs that are designed to pool in a specific part of the body and then we can use antennas to send a small amount of heat to that area and only heat-sensitive drugs get hot enough to kill the cancerous part while not harming the rest of the body.

Researchers have found an antenna-related diabetes solution as well. Today, people must prick themselves to test their blood sugar. There is a concept out there for a contact lens that has sensors in it to read the blood sugar from the eye fluid. This contact has an antenna that can communicate with a person’s phone and their doctor, so they know their blood sugar at any given time without drawing blood. The Internet of Things is really exciting when it comes to biomedical advances, and there is a lot of interest in this area. At our recent workshop in Santa Clara, this was a topic that many of our participants were interested in.

 undergoing hyperthermia 

How is CST supporting these advances?

One of the ways CST is supporting these advances is by having accurate biological material properties for models because a simulation is only as good as the model and that’s complicated in this area. We also provide dedicated post-processing tools which allow medical professionals to be able to understand and to use these simulations. Many of them aren’t engineers, so we have to find a way to convert these EM fields and images into quantities they will understand.

CST Workshops are a great chance to learn about EM Simulation in general, and our bio-EM specific workshops offer detailed insight into IOT, sport wearables, and medical advances. The workshops are always different based on where they occur and who attends, so while providing the same information about our software and the benefits of simulation participants also get to be involved in a variety of interesting conversations.

CST engineers on International Women in Engineering Day 2017


CST is lucky to have incredible engineers working throughout our company. In honor of International Women in Engineering Day, we spoke to some of the women who contribute to CST’s success about what they love about being engineers and how male allies in the field can support gender parity in engineering in the future.

Irina Munteanu, 
Head of market development and strategic projects. 
Ph.D in Electrical Engineering.


Apra Pandey, Senior Application Engineer. Ph.D. in Electrical Engineering, specializing in Photonics and Metamaterials.


Tracey Vincent, support application engineer. Ph.D, Material Science.





What is your favorite thing about being an engineer?

Irina: Diversity – I never get bored in my work as an engineer. Engineering is a combination of precision (but not as much as in mathematics), creativity (but somewhat different from an artist’s), and detective work (“which one of the myriad of tiny technical details in my device is to blame that it doesn’t yet work perfectly?”)

Apra: 
The best part about being an engineer is to be able to conceive new ideas, design and implement them to make our lives better.

We are witnessing tremendous technological growth, and an important ingredient of this is curiosity. Being curious about how things work, why they work, can they work in a better way, how can a certain design be improved, etc. is what helps us progress.

One of the quickest ways to see if an idea would work is by creating a virtual prototype of the design; or in other words, creating a simulation model that represents how the design would work. I enjoy being able to simulate the design ideas and suggest whether an idea would work or if there is something that can be done to improve the design. This leads to not only a reduction of production cost, but also a faster design cycle.

Tracey:
 Engineering is being paid to solve puzzles and I love solving puzzles. I love the interdisciplinary nature of the work I do.




The theme of INWED this year is “men as allies”, what is a way that men can support women working as engineers or getting degrees in an engineering field?


Irina: I find it difficult to give a general answer to this question, but I can give a few examples from my life.

I was lucky to have a father who often asked me to help him when doing small repairs at home, so I knew even as a little girl how to bang in a nail, change a bulb, or what different types of pliers are good for.

My uncle convinced me that studying engineering is not in contradiction with following my literary and liberal-arts interests: “with a safe job and a good salary in your pocket”, he said, “what prevents you from learning foreign languages, write books, or paint?”

Later on, I learned that some male professors or colleagues tend to think of women in engineering in extreme ways – either “this much is still not enough” (and for them, it’s never enough), or exactly the opposite “in your case, this little will suffice”. I am extremely grateful to those several male professors, colleagues, mentors, who asked of me exactly the same as from my male colleagues, not more, but also not less.

Apra: 
I think there are quite a few ways men can be allies. By being more supportive at the domestic front, by fostering a respectful environment and creating more opportunities for women to take up more engineering roles; are a few ways in which men can support women.

Tracey: If you’re a dad and an engineer then build a rocket with your daughter, encourage her to do math and show her how math is the language we use to understand and analyze the world around us. When you talk to your daughter or son, try to use “he” and “she” interchangeably to describe engineers and scientists. As a boss - call on the opinion (especially in meetings) of your female employees or at least have turns – research shows women are constantly interrupted/talked over; give her the time to be heard. If she has good ideas or did good work then laud her publically if possible. Believe she can do it and give her tasks that stretch her. Women wait to do things when they feel they have full competence; men take risks and challenges and use them as opportunities for growth – this is because society is more forgiving of rookie mistakes with men. I would like more men to see and understand this bias.

Are there any publications, workshops, webinars or other work of yours you'd like to share with readers of the CST blog?


Irina: The article that might be of most interest for readers of CST blog is probably a paper I co-authored on Time Domain methods called “It’s About Time”.

Apra: There is an upcoming presentation at IEEE-APS in San Diego on July 10th. The paper is titled, “Accurate and Efficient Simulation of Bioelectromagnetic Models“

Tracey: I will be participating in a New Features 2017 workshop in Framingham, MA (Boston office) on the 13th July. I will also be participating in the “online training series” over the summer geared to new users and college students.

Bio-electromagnetic simulation with Dr. Tilmann Wittig

Following the success of CST's recent bio-electromagnetic (bio-EM) workshops, we sat down with
Dr. Tilmann Wittig, Principal Engineer and Market Coordinator for bio-EM to share an introduction to this challenging and fascinating subject.

First, what do you do at CST?

I coordinate the “Bio-Electromagnetics” market here at CST. We refer to bio-EM whenever we simulate an EM source like e.g. a mobile phone, an MRI, a hearing aid or a pacemaker inside or nearby biological tissue, which in most cases will be a full or partial human body model. In other cases, we may also use animal models or just simplified homogeneous phantom models, representing a kind of average human tissue.

So, what is so special about simulating an EM problem containing tissues? 


One major reason is that bio-EM is one of the few domains where measurement of electromagnetic fields is mostly not an option since we cannot, or at least don’t want to, put field probes into a living human. From a simulation point of view, we face the special challenge of having “wet” tissues with a high content of water that makes both the permittivity and the material losses quite high. In addition, we typically have to deal with complex shapes and various layers of materials with significantly differing properties. Depending on the type of application, these properties can have a severe impact on the device design and functionality. To make such devices work in the presence of complex human tissue distribution is often a challenge!

What kinds of devices are being simulated?

MRI image: Courtesy of German Cancer Research Center (DKFZ)

We have two categories of devices we deal with: First, are devices we want to penetrate human tissue, that’s, for example, MRI or other imaging, pacemaker simulation, where the pacemaker is implanted, or any kind of implant for which there may be wireless charging. So, in that case, we want to be able to send an EM signal inside the body which is much more challenging than it may appear at first glance since high permittivity materials will reflect large amounts of the electromagnetic waves. The problem gets especially hard if we have several layers of biological tissue with very different permittivity e.g. from the skin, via fat and muscle to bone.

Second, we have devices where we just want to communicate in the presence of the body, like a mobile phone or various Bluetooth or soon IoT devices. With such devices, we’d be happy if nothing went inside the body because this means unwanted losses in the body due to penetration. That increases power assumption and affects the battery lifetime of the device but even worse: the problem is, we aren’t quite sure where that energy is placed and what effects it may cause inside the body. The only simulation can give us a hint how much power we have with a certain body position!
Due to the potential hazard, it is also a governmental requirement, every device that’s intended to work in or around the body needs a certificate of its SAR (Specific Absorption Rate) value. You’ll see what the SAR value is, for example, in the small print on your phone and the lower the value, the
better because less energy is going into your body.

Bio-EM is a challenging domain with a large variety of applications. It is important that a device which is intended to work inside or nearby the body is designed taking into consideration a body model to guarantee functionality in this environment, and that at the same time the power levels inside the body are well controlled. It’s interesting that these two kinds of optimization goals are contradictory. We have some customers who need penetration and they are trying to optimize to maximize the penetration like an MRI, and then we have customers who make mobile communication devices and they are optimizing for minimal penetration. 


Dr. Tilmann Wittig
Stay tuned for part two of this interview, in which Dr. Wittig shares the most interesting medical innovations being developed with the help of bio-electromagnetic simulation.
