    Elizabeth Wins International Poster Award

    January 29, 2021

    "Enhanced visualization of ultrasound contrast agents using normalized singular spectrum area and singular value thresholding"

    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.

    Improving Prostate Cancer Diagnosis: New Coulter Award

    October 12, 2020

    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 Earns Fellowship from the American Heart Association

    January 07, 2020

    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.

    Hossack Lab at IEEE in Scotland

    October 21, 2019

    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. 

    Announcing Our Latest NIH R01

    April 24, 2019

    In 2018 Hossack Laboratory received a new four-year National Institutes of Health R01 grant to investigate catheter-based generation of special-purpose microbubbles for rapid erosion of embolic clots. Venous thromboembolism (VTE), comprising Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE), results in significant mortality, morbidity, and societal cost. There are approximately 900,000 recurrent, fatal and nonfatal VTE events resulting in 300,000 deaths annually in the US. With this four-year grant, extendable to five years, Hossack Lab will be supported by two R01s, and thus will have secure funding for the duration of incoming PhD students. Additionally, Hossack Lab receives significant support from two NIH grants to UVA colleagues, Dr. Sasha Klibanov and Dr. Mark Okusa, with projects involving ultrasound molecular imaging and ultrasound-based therapies for ischemia-reperfusion injury, respectively. The lab has also had a highly successful record with smaller grants such as the Coulter Partnership grant, funded by the Coulter endowment to the UVA BME department, investigating the capabilities of ultrasound for breast cancer therapy monitoring. Taken together, Hossack Lab is well-positioned to grow and thrive in the coming years.
