The functional microstructure of tendon collagen revealed by high-field MRI

The recent edition of Magnetic Resonance in Medicine has our article on using T2 to assess tendon microstructure. Congratulations Kelsey!

Backprojection - filtered vs unfiltered

I previously posted about the concept of reconstructing a CT image using the sinogram by performing the inverse Radon transform. The Radon transform is implemented using backprojection, taking the scan projections <sinogram> to reconstruct the original image. Because the data are digital, simply backprojecting the rays does not properly reconstruct the original image. In the examples shown below, the original image is a square at the centre of the field and the videos below show image reconstruction using backprojection, with and without filtering.

SPIN farming in Kelowna - urban agriculture

pic: SPIN CSA Kelowna Green City AcresI have been watching a double-lot sized garden grow since I moved to Kelowna -- it is on my walk to work. I learned more about the garden at the Farmers' Market this morning. The plot I walk past is one of 6 SPIN urban farming plots operated by Green City Acres. They move produce around the city, to markets, between gardens, and to restaurants using bycicles! They also have a community supported agriculture (CSA) program.

Proof that gmT2 is the reciprocal of gmR2

I just published an article in the journal Concepts in Magnetic Resonance Part A. The concept of this article came out of a debate I had with one of my examiners during my PhD defense <I was right ;-) >.

Tara's pregnant!

I knocked up my highschool girlfriend. :-)

A gadget's life

The Washington Post has a some neat infographics describing household penetration, cost, and annual sales of various gadgets, from monochrome TVs and fax machines to digital TVs and portable mp3 players.

Taking great notes

I wish someone would have sat me down prior to my university courses and outlined a few note-taking tips, like those from Lifehacker. The Cornell Note-taking Method would have been useful back then, and presently I think I'll benefit from Symbolizing the Next Action.

A Native American in Iceland 1000 years ago?

Could a Native American woman returned with Icelandic explorers 1000 years ago? Recent genetic evidence spurs this hypothesis <via BoingBoing>. <American Journal of Physical Anthropology article>
