Challange for the visual mind November 24, 2008
Posted by tomography in Challange.add a comment
1,500 dollars for a solution? I guess its worth taking a week off of school/work to solve this puzzle. Where to start, though? Look:
Clues given so far:
- Clue 1: The code is read from left to right, beginning with the upper leftmost corner.
- Clue 2: Colors from similar spectral families are considered to be the same (example: pink is equal to red)

Dedicated pdf. search engine November 24, 2008
Posted by tomography in search engine, SEEKRadiology.add a comment
I was happy to hear about PdfGeni, the new dedicated search engine for pdf. type documents, though after I tried it, I had mixed feelings about it. It is not as good as I expected, thought it is not too bad either. The layout is simple, clear, no problem with that, but it tends to bring up fuzzy search results such as main URL’s and unrelevant pages from different books. It did however come up with very useful and never-before-seen results for my keywords: “nuclear medicine” and “pediatric radiology.”
In any case it is a solid engine, though it is still in beta, and if developments continue, this will be a search engine worth putting to our SeekRadiology project.

Dear Readers!
It has come to my attention that the feed offered by TomographyBlog.com for the last couple of months was not working properly, so today I fixed this problem. Starting today, our correct feed URL is: http://feeds.feedburner.com/tomographyblog . I apologize for any inconveniences that this change has or will cause to anybody, but it has been necessary. I hope you will continue reading this blog via feed or by visiting the webpage.

Researchers capture motion of arteries, lungs November 18, 2008
Posted by tomography in CT, Radiology.add a comment
Computer tomography has a very high cost/benefit value, and thus is very popular in medicine in general. Capturing high resolution images of the body in no longer an obstacle with today’s modern scanners. However, even the latest and most expensive scanners may have a hard time capturing the motion of arteries and small airways without considerable distortion. Researchers at the RIKEN Advanced Science Institute in Wako, Japan, have developed a system that allows for the capturing of such high quality images in rodents.
They used synchrotron radiation at the SPring-8 Center in Harima, which is much more powerful and predictable than standard laboratory sources, and so achieves high contrast resolution and minimizes blur (Fig. 1). The shutters for x-ray source and detection were synchronized. The sample rodents were anaesthetized, put onto a ventilator, and connected to an electrocardiogram (ECG) machine. The researchers were then able to acquire data at controlled airway pressures and time observations for the periods between heart contractions. For heart and arteries, image acquisition could be timed for the end of breath expiration.
Images acquired with this technique allow for the calculation of gas exchange in small airways, and of shear stress in blood vessels.

Heath Docs – A weekly overview of health related issues that circulate the Web!
Let’s see what is making the headlines this week in the medical community:
1. Philips develops iPill, the “intelligent pill” that may deliver drugs to targeted locations throughout the digestive system. The pill monitors pH thus pinpointing its location.
2. German doctors cure patient suffering from AIDS. He has been free of disease for 2 years now!
3. Honda makes walking assist device available. It not only helps patients with neurological disorders walk easier, but it also helps hold the weight of patients thus enabling them to “sit” whenever it is necessary.
4. Google helps keep track of the flu epidemic online, 2 weeks ahead of CDC!
5. Attendees to this year’s American Society For Reproductive Medicine conference were lucky enough to receive these USB memory sticks:

Liver fibrosis detected with MRE November 4, 2008
Posted by tomography in MRI, Radiology.Tags: MRE, MRI

Researchers at Mayo Clinic were able to show that magnetic resonance elastography (MRE), a modality that looks at tissue stiffness, can identify early signs of hepatic fibrosis. MRE can possibly become one day a noninvasive diagnostic technology of choice for liver fibrosis, replacing the percutaneous liver biopsy that we have to do nowadays.
