Imaging Technology

Advanced brain scanner allows neuroimaging in moving subjects

A new innovation in brain scanner technology promises high-resolution neuroimaging in subjects without restricting their head and body movements. Neurons are specialized cells that are designed to generate electrochemical signals. These signals are the currency used to transmit information across the body. Neurons connect the brain, spinal cord, and each nook and cranny of our body to form information highways, transmitting sensory and motor information to different cells and other neurons in the body in the form of electrical impulses. Electrical currents also produce a magnetic field, proportional to the magnitude of the current that is producing it.

MRI device that could enhance medical diagnostics

A Purdue-affiliated startup, MR-Link LLC, is developing a coin-sized, affordable device that once inserted into existing MRI machines could allow researchers and medical professionals to perform multiple imaging scans at once and more efficiently and effectively understand a patient’s physiology.   Ranajay Mandal, a graduate student in Purdue University’s Weldon School of Biomedical Engineering, Nishant Babaria, graduate student in the School of Electrical and Computer Engineering, and Zhongming Liu, an assistant professor of electrical and computer engineering and of biomedical engineering, co-founded MR-Link to further develop and commercialize the technology.

Optical technologies could lead to novel treatments for neurological diseases

Optical technologies previously used to look at the stars in the sky will be miniaturized to look inside the brain, and could lead to new treatments for neurological diseases. The technologies once used to make corrections to space telescopes, along with new lasers, will help answer a fundamental question, according to Prakash Kara, Ph.D., a researcher at the Medical University of South Carolina: “Is there a universal microcircuit that is repeated everywhere in the brain with regard to how neurons communicate with blood vessels?” Kara is part of a team at MUSC that was awarded a $4 million grant from the National Science Foundation through its Experimental Program to Stimulate Competitive Research (EPSCoR). The grant will fund collaborative research between MUSC and the Univers...

Combining Imaging Technologies Could Provide Better Understanding of Brain Function

Combining two imagine technologies, such as MRI for structure and MEG for activity, could provide a new understanding of our how our brain works. New advances related to new uses of imaging technologies could help scientists uncover the brain’s mysteries. Now, European scientists have successfully combined magnetic resonance imagining, or MRI, scanning with an emerging imaging technology called magnetoencephalography, or MEG. There have thus bundled two ways of imaging the brain in one helmet-like device. Because MEG records the magnetic fields produced by our brain, as brain cells fire off messages to one another, it gives scientists a real-time insight into our brain as it processes its world around it. MRI, meanwhile, gives structural images of the brain by looking at blood flow a...
