Success!

I'm sure this will come as somewhat of a shock to my regular readers, but curiously enough, I actually manage to get some work done here in Switzerland, every so often. Today was one of those days. As some of you have probably heard, the project I'm working on here is a micro-MRI system. Basically, we want to take microscopic MRI's of interesting chemical or biological samples. My job was to build the "gradient" imaging system which is responsible for making the "pictures" -- if you've ever been in an MRI, you'll also recognize it as the thing making the horrible, loud noises that you hear. Although there have been a lot of ups and downs -- mainly downs -- I finally have the prototype system up and mostly working. Last night I took an image, and this morning I did some very, very basic analysis of the data. Here is the result: Fig. 1: MRI image of PDMS sample. The x and y scales are in microns (0.001 mm), thus the total range of the image...
