medical imaging

December 16th, 2011

So glad I found this great introduction and overview of medical imaging.

I liked the article since it gives a great overview of different techniques together with their genesis. Stuff like a PET scanner does not rain down on humanity. Lots of people needed to work hard to realize it. Ideas, Patents and -as it turns out- the Beatles were needed and involved.

I personally found it fascinating how much ample computation power has enabled. Nothing that mattered in the last 40 years would have been conceivable without massive numerical processing. Even 99.999% of computing power is wasted on Facebook and games it is just awesome that we people deviced instruments to compute so cheaply.

It is probably impossible to estimate the impact that technologies like DfMRI will have on our knowledge and picture of ourselves. The microscope changed the world and each of our lives in the most radical ways. Which might only have dawned on people in the 17th century.

Of course the link was found in Wikipedia. After having set up a monthly donation to them and knowing how good it feels now and will do in the future I wonder why I did not do so earlier. Specially learning new things most Wikipedia pages allow a quick overview about the topic. What I personally really love is how detailed yet concise even very specialized topics are being documented. Quiet brilliant.

This seems to be a caching issues. The workaround was to simply alter the URL in a way that would not have any effect on the feed:
