My assignment for the AAPM task group I'm on is to write a background blurb on the effect of reconstruction filters on CT images.
It's always hard for me to get started when it comes to writing stuff like this, or writing papers. Where to begin, what to talk about, how to organize it... Once I can get started, I'm usually OK though. Getting started is the hard part.
So far, my plan is to have a brief overview of the image reconstruction algorithm, emphasizing the filter. Then a discussion on different classes of filters along with how they affect the image.
