Before They...
Jimmy Nelson shares amazing photos from his journeys, documenting everyday life of many tribes. I have a follow up post when I find more of the elusive Copious Free Time.
This project is just amazing. Fashion photographer Jimmy Nelson goes to live with 30 tribes nearing extinction and brings back beautiful photos that will stand the test of time. I think we'll be getting this book...
Project home:
More photos (tons of them, all incredible):

Open-Source CT?
Can you make your own CT scanner? Dr. Jansen has a blog documenting how he did just that and shared it with Make Magazine. It's really well done and impressive. Unfortunately I have to rain on the party just a bit. I doubt many people are going to be able to replicate this and if they do, keep in mind the image quality is nothing near even the cheapest, commercial system. Not many people will have access to an oscilloscope to tune the detector and I didn't see where the Barium-133 source was purchased from. I would guess you can't buy one without a license from your state's radiation safety department.

We converted a specimen scanner, i.e., a 2D x-ray scanner, into a 3D computed tomography scanner, by adding a very precise motor, to rotate the sample. We reported it here:
HiSStology: high spectral and spatial resolution magnetic resonance imaging detection of vasculature validated by histology and micro-computed tomography.

In Fig 8, you can hopefully see some of the blood vessels and bone. Think of it as looking at a chicken drumstick from the side, with the foot on the right. Contrast that with the very pixelated images of the avocado and bell pepper below. Again, I'm sorry to be a party pooper, but I don't think people should expect to build something comparable to a clinical or pre-clinical CT scanner.

Hehe yesss that free time thing... actually I have shared the project with another radiographer and lecturer friend of mine. I'm hoping between us we can find some time and use for it.

Mercy Mercy Me (the Ecology) - The Strokes, Eddie Vedder & Josh Homme (Marvin Gaye cover)
Happy #Earthday and #TuneTuesday .

Woo ah, mercy mercy me
Ah, things ain't what they used to be, no no
Where did all the blue skies go?
Poison is the wind that blows
From the north and south and east

Woo, mercy, mercy me, mercy
Ah, things ain't what they used to be, no no
Oil wasted on the ocean and upon our seas
Fish full of mercury

Ah, oh mercy, mercy me
Ah, things ain't what they used to be, no no
Radiation underground and in the sky
Animals and birds who live nearby are dying

Oh mercy, mercy me
Ah things ain't what they used to be
What about this overcrowded land
How much more abuse from man can she stand?

Oh, na na
My sweet Lord, no, no, no, na na
My lord, my sweet lord

You missed again
Based on +Damon Schooler's post:
I think it's worth re-sharing this.
Hey Ref
Are you pregnant because you missed two periods.

A little. Howard was a big reason game 2 was done after the first period.

This post won't die
Sorry #ScienceSunday  peeps. I'm too lazy busy to write a new post for Easter. So I am yet again, resurrecting this post.

If you want to learn more about CT:
Medical Imaging 101 pt 2: CT
Peeps Show Cancelled
In a previous post, I mentioned that I would image some peeps with Computed Tomography (CT), I did that below. However, I wanted to use the peeps to show the difference between CT and magnetic resonance imaging (MRI). I suspected that the peeps wouldn't have enough free water to image with MRI so I had a plan B. I planned on injecting Barium Sulfate (BaSO4) which would be bright in CT because it's more dense than water and it would hopefully be bright in the MRI because of the water in the BaSO4 solution. It turns out that I could not inject enough. It just oozes out. So the MRI was a bust. Since I'm good at procrastinating, I didn't want to come up with a plan C. Also I couldn't find any Zombie Peeps with cancer to image. Hence the Peeps Show is cancelled.

Since the CT worked, I can at least describe that. The bird peep has a voxel size of 130 micron and the bunny peep has a voxel size of 150 micron. The left column was acquired with 40 keV which, for in vivo imaging, would typically give better soft tissue contrast (not as good as MRI, but that's another story). The right column was acquired with 75 keV which is typically better for bone imaging (not really possible in MRI).

In the bunny peep, you can see the BaSO4 that was injected. The video demonstrates that these are in fact 3D, i.e., tomographic images.

If you are interested in how peeps are made, here's the link.
Now I have to work on something else for #sciencesunday

I'm the medical imaging, Red Wings, Formula One, Tech guy.
I'm a scientist/engineer interested in image based biomarkers, i.e., non-invasively visualizing disease or response to therapy. I mainly research cancer using MRI, PET/SPECT/CT, and EPRI but I'm also interested in cardiovascular research.

Sports: Big formula one fan, Detroit Red Wings, Chicago Bears, and Chicago White Sox.

Music: I like pretty much everything except country. Big fan of Pink Floyd. Bob Marley is a god-like-hero. I love house music when I'm programming or doing image analysis. Miles Davis is a mutical genius (say it in Gumby's voice).

Misc: love dogs, science/technology (gadgets), cars, bicycling... Also Member of The Incorrigibles.

My passion is science and science is my career choice, so I am grateful to be a co-curator for #ScienceSunday.

Don't circle me if you are not open minded and interested in science. I'm very much against the anti-intellectualism/anti-science movement.

There is a cult of ignorance in the United States, and there always has been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that "my ignorance is just as good as your knowledge."
     Isaac Asimov, column in Newsweek (21 January 1980)
