What is my goal with How Radiology Works?

          Provide easily accessible online training material.
Emphasize direct explanations.
Focus on important physical concepts in Radiology.


I am a Scientist at GE Healthcare by day and an online instructor running this site by night.


I deliver online training to you (the Radiologic Technologists) to help drive improved medical imaging and better patient outcomes..


I think that understanding radiologic physics will empower you and that it can even be fun to learn.

After working in x-ray medical imaging for fifteen years (x-ray and CT) as part of my day job I began to have more and more interactions with radiologic technologist and radiologists. I realized what should have been obvious from the beginning that you as a radiologic technologist have the greatest impact on the quality of the medical images that are taken for the patients. 

As a developer of new imaging technology it is tempting to always want to solve problems with new fancy features, but after several years of working in that direction I realized that to help patients it is equally important to share useful information on the physics of Radiography and CT.

As a radiologic technologist you have told me that this isn’t your favorite topic but that it is very valuable for patient care that you understand why you are using certain technical parameters.

I was off from work for six weeks after my second son was born. This was a blessing as I didn’t have any formal paternity leave with my first son who had ended up in NICU for a month. During my leave I listened to many podcasts while rocking my new baby to sleep. I stumbled upon some podcasts with the message to make something valuable and worth sharing, aside from what you do at work.

After considering several options I decided to pursue my love of teaching with this online format designed at empowering you as a technologist to have fun with physics (or at least get through it).

So the beginnings of How Radiology Works came from those long days and nights after my son was born, and my genuine desire to help improve your understanding of concepts in Radiology so that all patients get the best scan possible.

New Technology is Cool

As with any self respecting scientist/engineer in medical imaging I am always excited by the newest bells and whistles enabling new clinical applications, improved workflows or significantly improved image quality..

The Fundamentals Rule

Even though machines are getting smarter all the time there is NO SUBSTITUTE for you to have a good baseline knowledge on how the technical parameters affect image quality.

Technologists determine IQ

Since you are driving the scanners day in and day out and changes to the imaging protocols are often required, you need the ability to adapt the imaging techniques to each patient. 

These folks can vouch for me.

Started How Radiology Works Website

After a couple years of putting material together I started adding it to the web.

Started at GE CT

In the first few years at GE CT I had to privilege to contribute to exciting projects like cardiac motion compensation (SnapShot Freeze), widecone image reconstruction (Revolution CT) and neuro image reconstruction.

Visited Erlangen

During a Post Doc with Guang-Hong Chen I was able to spend several weeks over the summer working in Erlangen Germany in Willi Kalendar’s group. The highlight there was tapping the keg and getting covered in beer while executives from Siemens in suits narrowly avoided the spray.

Graduated From UW Madison

I studied Medical Physics, specifically Medical Imaging and within Medical Imaging my dissertation was on image reconstruction for CT within Guang-Hong Chen’s research group. My claim to fame is being the first student to work with Guang-Hong, with Shuai Leng a close second arriving just a few weeks later.

Graduated From Michigan State University

In undergrad I majored in Physics and Computer Science. I worked in the National Superconducting Cyclotron Lab NSCL on campus in Bill Lynch’s lab. While there I proposed and built a laser based alignment system.
Also while at MSU I received the nickname nettforce from my pre-dental room-mate. I still answer to that nickname when hanging out with college friends.
