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. Microw........ 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 »

Bug’s view inspires new digital camera’s unique imaging capabilities

by Perikis Livas in Chilon

An interdisciplinary team of researchers has created the first digital cameras with designs that mimic those of ocular systems found in dragonflies, bees, praying mantises and other insects. This class of technology offers exceptionally wide-angle fields of view, with low aberrations, high acuity to motion, and nearly infinite depth of field.... 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 ........ Read more »

Evolution Doesn’t Need Competition, After All

It’s been taken for granted since Darwin; species evolve through competition with each other for scarce resources. Then, the “more fit” adaptations can reproduce and propel the evolutionary process that much further.... Read more »

Patterned Hearts

by Perikis Livas in Chilon

A team of bioengineers at Brigham and Women’s Hospital (BWH) is the first to report creating artificial heart tissue that closely mimics the functions of natural heart tissue through the use of human-based materials. Their work will advance how clinicians treat the damaging effects caused by heart disease, the leading cause of death in the United States.... Read more »

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 ........ Read more »

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 loc........ Read more »

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 s........

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 researc........ Read more »

Temple of the Autonomus Machine

by Perikis Livas in Chilon

A news item over at Archaeology reports that a little wireless robot called Tlaloc II-TCwill soon “investigate the far reaches of a tunnel found beneath the Temple of the Plumed Serpent at Teotihuacan,” entering a chamber “estimated to be 2,000 years old, and [that] may have been used as a place for royal ceremonies or burials.”...
