Designers favourite in Radiology

leave a comment »

Radiology and Design might not be so different after all. Image editing is something a designer does as well as the radiologist. And they can actually use the same tool: Adobe Photoshop. There is an extended version of Photoshop for medical image viewing and editing. And it seems to be a success (at least Adobe and Dr. Joseph M. Bailey think so)

Visualizing Time and Movement

with one comment

Body-changes over time (like muscle movement, blood flow, brain activity) could be interesting for Radiologists to see. Todays medical scanners are able to track these changes and produce high resolution 4D images. But what is an appropriate way to view and analyse this data. A 3D model in which you can modify the timeline and the viewing direction is the most simpel way to view these images. But are there other smarter solutions and how do we combine images from different scan sessions, scans that are maybe days, weeks or years apart. With upcoming electronic and linked patient records this could be possible. (I need to check if this is needed at all.)

Recreating Movement
is a diploma thesis by Martin Hilpoltsteiner at the University of Applied Sciences Wuerzburg, Germany, Communication Arts. It has some very unique ways of analyzing movement in videos. The basic idea is to extract all single frames of a movie and arrange these in different ways to make it easier to analyze movements. It also uses coloring and tracking filters to emphasize special features of the movement. In his work Martin gave some examples of analyzing sports movements, and car crash tests. I think it could also be applied to analyze medical video or 4D data.

Sports movement – Here you can see the movement of a baseball player. The background is removed so you can only see the player. In the example videos you can also see comparison of two different movements or the same movement with different filters.
