Extensive use of simulations with a few experiments thrown in for good measure. Upshot of this article is that the standard 15-20% energy windows most people use aren’t optimal for Ga-67 imaging. What I also found interesting was that the optimum windows changed depending on the task being performed (detection vs estimation). Results were based on SNR calculations, but did not look at any changes in image quality. Only planar images were examined in this paper. It would be interesting to see how the modified windows affect Ga-67 SPECT imaging. With 5/8″ crystals coming into vogue now, it would also be interesting to see if the optimum windows change with a thicker crystal. I’ll have to file that away on my list of projects to get to. That might make an interesting subject for a summer student to tackle.
I don’t think I can eat Quizno’s Subs anymore
I really think that Quiznos Subs got ripped off by whatever ad firm created their latest commercials. Maybe you’ve seen them. They feature a freaky looking white turd-like lump with a bad singing voice, which on closer inspection appears to be a dead mouse with really bad teeth and creepy bulgy eyes. And then there’s that pirate looking thing playing the guitar. I don’t know about you, but a dead mouse singing really badly about Quizno’s doesn’t make me want to eat a Quizno’s sub anytime soon. There really isn’t anything about those two (yes, there are two of them) commercials that make me even want to step near a Quizno’s.

A new PDA
Decided to go for the PDA upgrade, so in a few weeks, I should have a new Tungsten T3 to play with.
A few people around here with Tungsten C’s asked why I didn’t get one of those with the cool wireless capabilities. Wireless is nice, but not important to me for what I want to do. I wanted the larger screen to make it easier to deal with the spreadsheets I use while I’m testing equipment.
Can’t wait till it gets here…
MT 3.0 ready for alpha testing soon
Looks like SixApart is ready to start alpha testing MovableType 3.0 soon. I’ll probably wait for beta testing to start, seeing as how there isn’t much activity on this blog to warrant being on the bleeding edge. But ifyou’re interested, drop them a line.
Comet and Galaxy conjunction
APOD had a very cool photo yesterday showing the near conjunction of the Andromeda galaxy and Comet Ikeya-Zhang. More of the photographer’s very cool pictures can be seen at http://www.skylook.net.
