1)How to measure the thickness of the cortical mantle – this allows us to quantify when a certain region in the brain is getting affected by a certain disease and losing tissue
2)How to measure shape of subcortical nuclei – quantifying deformations from one shape to another
3)How to compute average shape and variability around the average shape for quantifying anatomy
4)A short introduction to the new Biomedical Engineering Program at School of Engineering Science, SFU.

Here’s what you’ll need to get started on your 3d scanning adventure..
- A camera (e.g. web cam)
- A hand-held line laser
- Two plain boards in the background
- A Windows PC
- DAVID-Laserscanner software (free)Once you’ve got your equipment together, print off the calibration sheets that are included with the David Laserscanner software and apply them to you 2 plain boards.
Your two boards must form a perfect 90 deg right angle, this is key to the scanning process.
Next, point your webcam at your calibration boards and turn off any image enhancements that your camera might have (i.e., ambient light boot, auto exposure, etc…).
Next we fire up the David Laserscanner software and auto calibrate our calibration boards. You must have as bright a room as you can get for this step, you almost want a complete washed out look for perfect calibration.
Once your done grab your line laser and turn all of the lights off, you want to make sure that the room is a pitch black as possible, all we want the camera to do is see the laser. Then, at a high angle, slowly pass your line laser over the object from top down, repeat the scan until you have a solid mesh form of your object.
Export your scan into an .obj format and load it up into your favorite 3d modeling program and enjoy.

iSquint is an iPod video conversion app for Mac OS X.
It’s many times faster than QuickTime Pro, works with almost all popular video formats, and it’s infinitely free-er. It’s also really easy. Just drag in your file, and click Start. You can also choose “TV” or “iPod” size, set your quality, or even go all-out by playing in the Advanced drawer.

- iMainGo
$40
If you want a portable little speaker for your iPod, as well as a protective case for your iPod, why not combine them into a single package? The iMainGo is a zip-open case that has your iPod on one side and a small stereo speaker assembly on the other side. It’s definitely thicker than your typical iPod protective case, but a lot more compact that most speakers…and hey, it sounds just fine for its size. It’s a bit heavy, and it doesn’t stand upright in any elegant way, but it still beats hauling around your typical speaker dock. Requires four AA batteries.Shiny
- very compact
- sounds pretty good
- adds protective layer over screen
Dull
- a bit heavy
- battery compartment awkward
- doesn’t stand upright all that welliMainGo

This site brings you two pictures, and then it’s snap-judgment time. Click the one you like better. Then repeat on a new pair of images. Why? Maybe just to kill time, or maybe after you’ve made your preference known on enough pairs of photos, LikeBetter’s “brain” will know a thing or two about just what kind of person you are . . . and what kind of people it can direct you to make friends with.
