X-Rays Imaging Uses Color to ID Bone Fractures

Researchers at the University of Maryland, Baltimore County (UMBC) and the University of Baltimore (UMB) are testing a new method of X-ray imaging that uses color to identify microfractures in bones. Microfractures were previously impossible to see using standard X-ray imaging. The findings associated with this advancement in color (spectral) CT imaging are published in Advanced Functional Materials. Dipanjan Pan, professor of chemical, biochemical and environmental engineering UMBC, and professor of radiology at UMB, is the corresponding author of this new study. Looking ahead to the next generation of X-ray technology, researchers asked, "How can we detect a bone microcrack, something that is not visible using X-ray imaging?" Researchers explained that to examine this question, they developed nanoparticles that navigate and attach specifically to areas where microcracks exist. Researchers call them "GPS particles." They started conducting this research at the University of Illinois Urbana-Champaign. The researchers have programmed the particles to latch onto the correct area of the microcrack. Once the particles attach to microcracks, they remain there, which is crucial to the imaging process. The particles contain the element hafnium. A new X-ray-based technique developed by a New Zealand-based company MARS then take CT images of the body and the hafnium particles appear in color. This provides a very clear image of where the bone microcracks are located. Hafnium is used b...
