主讲人简介：
Professor Zhihong Huang was awarded a BEng in Precision Instrumentation from the Tianjin University, China, and later received a PhD in the field in the Department of Mechanical Engineering at University of Glasgow. In 2002, Zhihong joined the University of Dundee as a lecturer in Department of Mechanical Engineering and was subsequently promoted to Senior Lecturer and Professor. She is currently a Professor of Biomedical Engineering and Associate Dean of International in the School of Science and Engineering.
Zhihong's main research interests are in medical ultrasound and photonics, working closely with clinicians and industrial collaborators to maximise research impact and facilitate translation into practice. She utilises acoustics and optics as tools to understand and explore the mechanisms of tissue response, which in turn support new research initiatives on tissue characterization and interventional medical devices.
She leads a wide range of activities incorporating tissue mimicking phantom fabrication; mechanical, acoustic, thermal and optical characterization of tissue; 3D reconstruction of human anatomy and simulation, vibration analysis and robotics.
报告摘要：
Improving the accuracy and safety is urgently needed during ultrasound guided interventional procedures including anaesthesia and cancer biopsy. There is a universal problem of imaging the needle, particularly the tip, due to poor visibility of the needle. The problem of tip location is further exacerbated by the long narrow gauge needles being easily bent and the tip trajectory deflected. Displacement of the tip can lead to very serious consequences, from pain to internal bleeding and loss of function or biopsy mis-sampling. Despite current improvements in technology such as improved needle design and needle guidance positioning, fine anatomy and needle passage are still rarely detectable, especially in deep locations and at steep insertion angles. One important solution is to design an innovative ultrasound device for enhancing a real time imaging of the needle and surrounding anatomy, easing penetration and reducing the deflection of the needle.
