Teaching Radiology on iPhone

I’ve been writing about Radiopaedia.org, the best radiology wiki managed by Dr Frank Gaillard, for years. And now new teaching files are also available on iPhone. An excerpt from the press release:

Radiopaedia.org is proud to announce the arrival of its iPhone application, ‘Radiology Teaching Files
Version 2.0’.

Radiopeadia.org is the most comprehensive on-line knowledge-sharing tool and learning resource for
the global radiology community.

As an extension of this mission, Radiopaedia’s Radiology Teaching File now available as an iPhone
application, provides access to this global knowledge bank anytime, anyplace, from the convenience of
their iPhone. The app, like the Radiopaedia.org website, includes comprehensive discussion and sample
reports and links to additional online content.

Here are some screenshots that give you a glimpse about how it actually works.

Scan Your Sample Under an Electron Microscope

I’ve recently received an e-mail from ASPEX that offers Scienceroll.com readers the opportunity to scan a sample of their choice with an electron microscope (Desktop SEM) for free. Here are a few examples.

What you have to do:

  • Fill out the form and mail it along with the sample you want scanned to:
ASPEX Corporation

Free Sample Submissions
175 Sheffield Dr.
Delmont, PA 15626
  • Once ASPEX has completed the scan, the images and report will be posted on ASPEX’s website here.
  • It should take about 2 weeks for the results to post to the ASPEX website, and submitters will be notified via email. Samples scanned for free will not be returned.

MRI Puzzle

What happens if you combine magnetic resonance imaging with games and creativity? See the idea of Neil Fraser:

Human Body as a Machine: Video

Fritz Kahn, a German gynaecologist born in 1888, was a real genius of medical illustrations.  More than a hundred years later Henning Lederer, audiovisual artist, paid tribute to this genius by creating the video below based on Kahn’s work. Enjoy:

From 2D MRI to 3D XBOX

Magnetic resonance imaging opened a new chapter in the history of medical diagnostics, but it still cannot answer all the questions. Researchers at the Iowa State University came up with a wonderful solution. They developed a software, BodyViz, that can convert common 2D MRI and CAT scans into 3D visualizations, enabling physicians to navigate inside the body using an Xbox controller.

Two-dimensional imaging technologies have been used in medicine for a long time, said  (BodyViz co-founder) Eliot Winer, an Iowa State associate professor of mechanical engineering and an associate director of Iowa State’s  Virtual Reality Applications Center. But those flat images aren’t easily read and understood by anybody but specialists.

“If I’m a surgeon or an oncologist or a primary care physician, I deal with patients in 3-D,” Winer said.

(The creators) like to quote a doctor who told a reporter that when preparing for complex procedures, “2-D is guessing and 3-D is knowing.”

Lego MRI Scan

The picture of the day award goes to the Voxel123 Flickr user who posted images of a Lego MRI scan.

NeuroTouch

Barbara Duck informed us about a new development, NeuroTouch, that will hopefully lead to a new era in neurosurgery.

NeuroTouch, the prototype simulator developed by Canada’s National Research Council (NRC) and several other research groups, gives surgeons a dry run in virtual reality before entering the operating room, potentially reducing mistakes.

First, patient data from functional magnetic resonance imaging (fMRI) is rendered into a 3-D, high-resolution model of an individual’s brain. After the model is loaded into the system, doctors can touch and manipulate tumors and other virtual objects on screens in real time using a physical instrument resembling a scalpel. The instrument has six degrees of freedom and re-creates the force-feedback of the real tool and the varying resistance of tissue in brain regions with differing toughness. Meanwhile, photo-realistic on-screen imagery shows the simulated surgery, including bleeding and pulsing gray matter.
