Medical FUSION: Frontier Ultrasound Imaging and Robotic Instrumentation

Abstract:  Medical FUSION (Frontier Ultrasound Imaging and Robotic Instrumentation) Laboratory focuses on the interface of medical robotics, sensing, and imaging, and to develop robotic assisted imaging systems as well as image-guided robotic interventional platforms, where ultrasound and photoacoustic (PA) imaging are two key modalities to be investigated and integrated with robotics. Ultrasound delineates structural information, and compares favorably with other imaging modalities with its high degree of safety, ease of use, and cost-effectiveness. PA imaging is a hybrid imaging modality merging light and sound, and reveals tissue metabolism and molecular distribution with the utilization of endo- and exo-genous contrast agents. With the emergence of PA imaging, conventional ultrasound and PA imaging can comprehensively depict not only anatomical but also functional information of biological tissue. The scope of innovation includes (1) co-robotic imaging, where a robotic component is essential to reduce user-dependency in ultrasound scanning, to build an image with higher resolution and contrast, and to miniaturize and simplify imaging platform and (2) PA-based functional image-guided interventions that give additional information for surgical guidance with high sensitivity and specificity. Further, we will also tackle (3) mathematical and algorithmic challenges behind computer assisted interventions such as hand-eye calibration to support these deployments. The developed systems will synergistically improve both image quality and surgical accuracy and specificity towards diagnostic and interventional applications. To achieve this, we will form a highly interdisciplinary team consisting of individuals who are experienced in robotics, imaging, chemistry, and biology.

Biography:  Dr. Haichong (Kai) Zhang received a B.S. and a M.S. in Human Health Sciences from the Kyoto University, Japan in 2011 and 2013, respectively. He received a M.S. and a Ph.D. in Computer Science at the Johns Hopkins University in 2015 and 2017, respectively. Since 2019, he is a new faculty member in the Biomedical Engineering and Robotics Engineering at the Worcester Polytechnic Institute, and the director of the Medical FUSION Laboratory. His research interests include advanced robotic instrumentation and imaging with emphasis on ultrasound and photoacoustics for biomedical applications.
