News briefs for the Hossack Lab
Hossack lab has a new Coulter Partnership Award of $136,00 for the design of a therapeutic ultrasound approach for the treatment of degenerative heart valve disease. The Principal Investigators are: John A. Hossack, Biomedical Engineering and Patricia Rodriguez Lozano, M.D., Cardiovascular Medicine. Clinical Co-Investigators include: Austin Robinson, M.D., Mohamed Morsy, M.D., and Christopher Kramer M.D., Cardiovascular Medicine and Radiology. New designs will be developed using Finite Element Analysis to evaluate technical tradeoffs. The project will involve simulation and in vitro testing. Some ex vivo testing will be performed subject to availability of suitable tissue.
Elizabeth Herbst has won a poster award at the annual European Symposium on Ultrasound Contrast Imaging, a top level inernational meeting in the field of ultrasound contrast. Her presentation for was chosen among a group of 16 presenters in ultrasound contrast imaging. Co-authors on the work include Dr. John Hossack, Dr. F. William Mauldin, and Dr. Alexander Klibanov.
Elizabeth’s project in ultrasound molecular imaging utilizes singular value decomposition-based signal processing techniques to automatically segment and identify ultrasound contrast agent signals based on their unique spatiotemporal signatures. This innovative filtering technique has the potential to improve the visualization of cancer and other vascular diseases in future clinical settings.
Congrats to Yanjun, Feifei and Elizabeth authors of the lab's four most recent publications:
Hossack Lab has been awarded $97K from the UVA-Coulter Partnership for "Super resolution molecular imaging for improved prostate cancer diagnostic performance." Our proposal addresses new methods of ultrasound parameter setting and signal processing to yield approximately five fold improvement in resolution for ultrasound imaging combined with imaging of molecular signature of cancer.
Elizabeth Herbst has won an American Heart Association Pre-Doctoral Fellowship! Her project focuses on the use of ultrasound molecular imaging to characterize the aneurysmal abdominal aorta.
Our publication on microfluidics-based sonothrombolysis was one of the top 10 cited articles published by Annals of Biomedical Engineering in 2018. Check it out!
Hossack Lab grad students Elizabeth Herbst and Yanjun Xie presented their research at the 2019 IEEE International Ultrasonics Symposium in Glasgow, Scotland. Yanjun's research focused on designing a feedback control system on the diameters of microbubbles produced by a flow-focusing microfluidic device. Elizabeth's research was focused on the use of normalized singular spectrum area to isolate unique signals from ultrasound contrast agents.
The second annual Athanasiou ABME Student Award Session will be held at the 2019 BMES Annual Meeting. Just six awardees have been selected from all papers first-authored by students and postdocs in 2018 in the Annals of Biomedical Engineering. Hossack Lab's Adam Dixon (PhD '16) is one of the six.
The World Molecular Imaging Society (WMIS) has awarded Elizabeth the Women In Molecular Imaging Network (WIMIN) Award and a student travel stipend for the upcoming World Molecular Imaging Congress (WMIC). She was selected for both awards based on the scientific merit of her submitted abstract.
Elizabeth is first author on a new paper published in Ultrasound in Medicine and Biology!
