摘要：医学超声目前主要是以成像为主要特点的重要疾病诊断工具，近年来在超声电子、材料、生物医学等学科的发展推动下，其功能不断丰富，集成像、操控与神经调控于一体，应用不断拓展。本报告介绍基于超声微泡的超声非线性成像、超声靶向分子影像以及超声载药技术；以及基于超声辐射力属性的超声生物力学测量与弹性成像技术、超声辐射力操控搬运技术与超声辐射力神经调控技术的最新研究成果。超声微泡在超声声场激烈下会激发成为非线性声学信号散射体和声源，当和靶向生物亲和素和蛋白结合后，能够有效与病变目标细胞结合，并被超声成像有效探测，形成基于声探针的超声分子影像技术。超声辐射力效应及其产生声场的设计可以实现生物组织的瞬态畸变和剪切波震动，可以成为生物力学参数测量的弹性成像技术。利用声辐射力可以实现对于细胞及微纳颗粒和载体的在体空间搬运和精准投放。超声辐射力可通过与神经元细胞表面机械门控离子通道作用从而实现神经调控，有望实现微观和宏观层面的超声无创神经调控及脑神经网络层面的调控，这对于脑科学研究和脑疾病治疗具有重大前景。

第四期报告题目：Computer-Assisted Endoscopic Navigation Systems and Beyond

时间：1月28日下午16:30

地点：学院C505

Abstract

Endoscopy is a widely performed procedure that involves either diagnosis of suspicious lesions or guidance for minimally-invasive surgery in a variety of organs within the body. Conventional endoscopy is on the way to its next generation of computer-assisted endoscopic navigation. To realize the endoscopic navigation, a variety of pre- and intra-operative sensory information, e.g., CT, MRI, endoscopic video sequences, ultrasound images, and external trackers, must be processed to guide endoscopic procedures successfully. This talk will discuss developing different context-aware endoscopic navigation systems with various information processing. Beyond that, recent augmented visualization in robotic prostatectomy is also discussed.

Biography

Prof. Xiongbiao Luo received his PhD degree in Information Science from Nagoya University Japan in 2011. After a half-year postdoctoral fellowship at Nagoya University, he worked as a research assistant professor until March 2014. He has extensive experience in image-guidance methods and external tracking devices for surgical endoscope navigation, clinical ultrasound navigation, computer vision and artificial intelligence for clinical procedures, and information processing in computer assisted interventions with publications on these subjects in flagship journals and conferences including IEEE Transactions on Medical Imaging, Medical Image Analysis, Medical Physics, and IEEE Transactions on Biomedical Engineering, MICCAI and CVPR. Prof. Xiongbiao Luo is also actively involved in his research community. He has been reviewer for the top journals in his research field including IEEE Transactions on Medical Imaging, Medical Image Analysis, IEEE Transactions on Evolutionary Computation, Medical Physics, and IEEE Transactions on Biomedical Engineering.  More recently he has been member of the Local Organizing Committee for MICCAI, the premier conference in this field as well as Program Committee Member for several important conferences. Now he works on image-guided and robotically-assisted procedures for prostate cancer surgery.
