BU researchers develop new metamaterial that can improve MRI quality and reduce scan time

Via EurekAlert | June 10, 2019

Could a small ringlike structure made of plastic and copper amplify the already powerful imaging capabilities of a magnetic resonance imaging (MRI) machine? Xin Zhang, Stephan Anderson, and their team at the Boston University Photonics Center can clearly picture such a feat. With their combined expertise in engineering, materials science, and medical imaging, Zhang and Anderson, along with Guangwu Duan and Xiaoguang Zhao, designed a new magnetic metamaterial, reported in Communications Physics, that can improve MRI quality and cut scan time in half.

Zhang and Anderson say that their magnetic metamaterial could be used as an additive technology to increase the imaging power of lower-strength MRI machines, increasing the number of patients seen by clinics and decreasing associated costs, without any of the risks that come with using higher-strength magnetic fields. They even envision the metamaterial being used with ultra-low field MRI, which uses magnetic fields that are thousands of times lower than the standard machines currently in use. This would open the door for MRI technology to become widely available around the world… Continue reading.


How Magnetic Metamaterial Improves MRI

Via Boston University | June 4, 2019

BU researchers Xin Zhang, Stephan Anderson, and their team at the Boston University Photonics Center, Guangwu Duan and Xiaoguang Zhao, designed a new magnetic metamaterial that can create clearer images at more than double the speed of a standard MRI scanner. In this video, learn how their magnetic metamaterial works. Read the full story, “Magnetic Metamaterial Can ‘Turn Up the Volume’ of MRI” on BU Research.


BU researchers develop ‘acoustic metamaterial’ that cancels sound

Via EurekAlert | March 7, 2019

Boston University researchers, Xin Zhang, a professor at the College of Engineering, and Reza Ghaffarivardavagh, a Ph.D. student in the Department of Mechanical Engineering, released a paper in Physical Review B demonstrating it’s possible to silence noise using an open, ringlike structure, created to mathematically perfect specifications, for cutting out sounds while maintaining airflow.

“Today’s sound barriers are literally thick heavy walls,” says Ghaffarivardavagh. Although noise-mitigating barricades, called sound baffles, can help drown out the whoosh of rush hour traffic or contain the symphony of music within concert hall walls, they are a clunky approach not well suited to situations where airflow is also critical. Imagine barricading a jet engine’s exhaust vent–the plane would never leave the ground. Instead, workers on the tarmac wear earplugs to protect their hearing from the deafening roar… Continue reading.

ENG’s Xin Zhang Is BU’s 2018 Innovator of the Year, First Woman Chosen

Via Boston University | October 24, 2018

Cited for translational research on use of metamaterials in MRI, acoustic technologies

Xin Zhang is well-known for her pioneering work with metamaterials in areas as diverse as magnetic resonance imaging (MRI), downwell sensor technology for the oil industry, and noise-cancellation acoustics. A College of Engineering professor of mechanical engineering and materials science and engineering, she is the director of BU’s Laboratory for Microsystems Technology (LMST), which focuses on interdisciplinary research in microelectromechanical and nanoelectromechanical systems.

“Zhang is a creative innovator. You describe a problem to her and she can solve it,” says Michael Pratt (Questrom’13), managing director of BU’s Office of Technology Development. “She’s a go-to person for getting something done. It’s a true quality of an engineer, right? She can use these fundamental technologies and solve important problems across various domains.”

Zhang’s translational research has earned her this year’s Innovator of the Year award, bestowed annually by the University on a faculty member who “translates his/her world-class research into inventions and innovations that benefit humankind.” The award was presented last night during BU Connect, an annual research and innovation showcase. Zhang is the ninth faculty member and the first woman to win the award… Continue reading.
