Microwave for breast imaging?

by Know Your Images in Know Your Images

When we hear the word microwave, we immediately think about the heating device we have in our kitchen. But the word microwave just means waves with wavelengths from ranging from 1 meter to 1 millimeter (corresponding frequencies are 300MHz to 300 GHz). Microwave technology has been used in several engineering fields, and biomedical engineering is no exception. Microwave technology is used in the Radio Frequency components for MRI, but it also can be used as an imaging modality of its own. Microwave Imaging is research in progress, but there have been a number of groups working on this, which makes me believe that this will be available soon.... Read more »

Zinc: The Perfect Material for Bioabsorbable Stents?

by Perikis Livas in Chilon

In 2012, more than 3 million people had stents inserted in their coronary arteries. These tiny mesh tubes prop open blood vessels healing from procedures like a balloon angioplasty, which widens arteries blocked by clots or plaque deposits. After about six months, most damaged arteries are healed and stay open on their own. The stent, however, is there for a lifetime.... Read more »

UF researchers develop ‘nanotrain’ for targeted cancer drug transport

by Perikis Livas in Chilon

University of Florida researchers have developed a “DNA nanotrain” that fast-tracks its payload of cancer-fighting drugs and bioimaging agents to tumor cells deep within the body. The nanotrain’s ability to cost-effectively deliver high doses of drugs to precisely targeted cancers and other medical maladies without leaving behind toxic nano-clutter has been the elusive Holy Grail for scientists studying the teeny-tiny world of DNA nanotechnology....

Dissecting Art, Intersecting Anatomy - Medical illustration

by Know Your Images in Know Your Images

Pauline Lariviere was an artist whose main contributions were made to the field of medical illustration. As a scientist in the medical field, medical illustrations are essential to education. I have already spent some hours drawing something in the computer for a paper or presentation. In old times, all illustrations were done by hand, but nowadays computers play an important role and medical images are often used as a basis to medical illustrations. Here is an example of a medical illustration based on a CT scan:The video is about an exhibition which pays a tribute to Pauline Lariviere. Dissecting Art; Intersecting Anatomy from Phillip Schalekamp on Vimeo.More about the history of medical illustration and the role of computers can be read in:Tsafrir, J., & Ohry, A. (2001).

What does the Muse CD cover have to do with Medical Imaging?

by Know Your Images in Know Your Images

This is Muse CD cover of their 6th album: "The 2nd Law":Indeed, this image is truly beautiful and remarkable. It is an image of the white matter fibers in the brain obtained with diffusion MRI (link). The image was obtained by the Human Connectome Project, which is a 5-year project funded by NIH to find the networks of the human brain. These networks will show how our brain communicates between different regions and give insight about the anatomical and functional organization of the brain. The project also has the goal to produce data that will help understanding brain diseases such as Alzheimer's disease. The data is available to the scientific community.So how do you obtain these networks? By applying computer algorithms to data obtained with different neuroimaging techniques: MRI, fMRI, diffusion MRI among others. These computer algorithms come from the graph theory. The application of these algorithms is extremely useful, because the algorithms analyze the network, reduce the complexity, find similarities and differences between different networks.A very nice science article for researchers not familiar with the topic:http://www.sciencemag.org/site/products/lst_20130118.xhtmlTo know more about obtaining diffusion MRI data or network methods, look into these two articles:- Hasan, K., Walimuni, I., Abid, H., & Hahn, K.

CT scans help Anthropology studies

by Know Your Images in Know Your Images

This video has caught my attention few days ago. Field Museum in Chicago has used a CT scan to help them with the face reconstruction of an ancient skull (12,000 to 15,000 year old). The great advantage of using a CT scan is that once you have scanned the skull, you can do the processing and reconstruction of the skull on a computer without having to touch it, which means that the skull is never damaged. The problem here is usually the transport of the skull to the CT scan, which are usually located in hospital or clinics. This time, they used a mobile CT scan, which travels to the museum instead of the skull having to travel. Moreover, the researchers used a 3D printer to obtain a model of the skull, which was then used by a forensic artist to do the final face reconstruction. The motivation behind this new scan was that the researchers were not happy with the face reconstruction done before, which made this skull look "too Neanderthal".After watching this video, I have look for publications which describe the techniques used, but I haven't found many detailed publications. However, I found this review publication (Lynnerup, N. (2010). Medical Imaging of Mummies and Bog Bodies – A Mini-Review Gerontology, 56 (5), 441-448 DOI: 10.1159/000266031), which I have read and although not too detailed about the CT scanning procedures, I have learned a few things: - Living tissues require different processing that dead tissues, because Hounsfield units are different. Bone tends to de-mineralize, while soft tissues tend to become denser (probably due to surrounding minerals).- Even that this type of scans are done since the 70's, new CT scans are also done, because technology has improved that new findings arise.- CT data can be easily shared with other scientists, while skulls and mummies can't. ...

Procrastination to find the most cited papers in Medical Imaging

by Know Your Images in Know Your Images

Few day ago, I was wondering what were the most cited (important?) papers in Medical Imaging in the last ten/five/two years. The problem was that I didn't know exactly how to find this information. I googled a bit around and I found a way and tried it out. I found also some extra information about the subject:Published Papers in Radiology, Nuclear Science and Medical Imaging Field: Citations in Radiology, Nuclear Science and Medical Imaging Field:It is interesting to note that it is increasing steadily every year.  Most cited paper in Radiology, Nuclear Science and Medical Imaging Field:- of the last 10 yearsJan, S., Santin, G., Strul, D., Staelens, S., Assié, K., Autret, D., Avner, S., Barbier, R., Bardiès, M., Bloomfield, P., Brasse, D., Breton, V., Bruyndonckx, P., Buvat, I., Chatziioannou, A., Choi, Y., Chung, Y., Comtat, C., Donnarieix, D., Ferrer, L., Glick, S., Groiselle, C., Guez, D., Honore, P., Kerhoas-Cavata, S., Kirov, A., Kohli, V., Koole, M., Krieguer, M., Laan, D., Lamare, F., Largeron, G., Lartizien, C., Lazaro, D., Maas, M., Maigne, L., Mayet, F., Melot, F., Merheb, C., Pennacchio, E., Perez, J., Pietrzyk, U., Rannou, F., Rey, M., Schaart, D., Schmidtlein, C., Simon, L., Song, T., Vieira, J., Visvikis, D., Walle, R., Wieërs, E., & Morel, C.

Seeing Stars

by Perikis Livas in Chilon

“WE’LL BE ABLE to see the beginning of the universe as we know it today,” says Charles Alcock, director of the Harvard-Smithsonian Center for Astrophysics (CfA) and professor of astronomy—imaging the radiation signatures from ancient galaxies billions of light years from his hilltop office on Garden Street, near the Radcliffe Quad. Addressing that same frontier, Abraham (Avi) Loeb, Baird professor of science and chair of the astronomy department, characterizes the research as “the scientific version of the story of Genesis.” Closer to home, so to speak, where the quest for “exoplanets” orbiting other stars has accelerated since the first discovery in 1995—and with it the search for chemical signs of life elsewhere—Wendy Freedman, chair and director of the Observatories of the Carnegie Institution for Science, in Pasadena, California, says, “We can now approach it from a scientific standpoint. It’s no longer science fiction.”... Read more »
