The end result they come up with is the same as mine, although their work was done on just one gamma camera and had a little more focus on image quality than mine did. I was able to do some cross-camera comparisons with my data and had a little more analysis on the core question (is T1/2 the same between collimators). I think mine still has a good chance of being published. Hopefully the reviewers will also think it's a worthy addition to this other paper. I just won't have first post bragging rights.
