Who is this blog for? 


The videos and blog posts are targeted towards Radiologic Technologist/Radiographers and students in training.

This is for Technologists and students who want a fun way to really understand the physics behind the scanners.

Who is this blog not for? 


This is NOT for Radiologists as they know everything already.

Also if you are a Radiologic Technologist just looking to do the bare minimum to get by this probably isn’t the best fit either.

Rad Newbie

For many students the physics section is the most challenging. If you are new to Radiology consider How Radiology Works an introduction to physics concepts in x-ray and CT. Learning about the physics of Radiology early will help you feel more confident when you cover the material in school.

Rad Student

If you are studying for the x-ray Radiography ARRT certification exam we have content covering important learning objectives identified by the ARRT. Repeated exposure (pun intended) to this material is great preparation to help you understand key concepts so you can ace your exam.

Rad Techspert

If you are a seasoned certified technologist we are here for you to brush up on important concepts and to provide teaching material that you can share with new technologists whom you are mentoring as they grow in their career.

We do plan to offer CE credits in the future. ​

Technologists’ View

Brian has created an easy to navigate website that helps us develop an understanding of the fundamentals of radiologic technologies. His high level of knowledge stemming from his industry experience, and educational background, combined with his low key personality and love of podcasts enables the learner a passive and familiar learning experience. He’s developed great place for us to brush up on radiologic technologies.

How Radiology Works should be a “go to” for hospitals to increase quality in imaging throughout modalities. The education is a perfect addition to a staff meeting or as a foundational guide for a fellow technologist to learn an advanced modality.

Brian did a really good job, he worked hard to make it as simple as possible and accessible to everyone! I’m very proud to be one of his first to take the training and I’m sure he has all the tools to become a benchmark for training for all radiology technologists !

The online radiology education videos are extremely informational and helpful. The use of detailed explanations with supportive graphics makes the information easy to understand. The ending recaps truly highlight the crucial information from each video.

Brian’s lectures are concise, well structured and informative. I would recommend Brian’s videos to any of my colleagues.

Have you ever wondered how the other modalities create their diagnostic images. These trainings will help to clear up the “magic” that is used to generate images across the halls of your department.

I really enjoyed the material presented in the courses. They are quite interesting and rich in radiology physics details.

Teaching the physics concepts with interactive sessions and presentations has really helped the students to learn physics better. I’m deeply inspired by the way How Radiology Works has meticulously created the information on radiological physics in your website.

I find the level of detail to a high standard, well organized and communicated clearly. It is rare to find high quality content such as this in Radiology training materials.

I am here to help you on your journey to be a be a RAD Hero. As a technologist you can improve the care for your patients with the help of RAD Physics. In order to help you on your RAD journey we started How Radiology Works(see About for details). I am using the knowledge from 20 years experience in x-ray and CT Imaging teach you best. I received my PhD from the Medical School at UW Madison. Currently I am an Adjunct Asst. Prof. at UW Madison and a Principal Scientist at GE Healthcare.
