我公司領(lǐng)軍人應(yīng)蘇州大學(xué)邀請(qǐng)，于4月13日下午在蘇州大學(xué)電子信息樓為蘇大學(xué)子做一份關(guān)于“微型內(nèi)窺鏡三維實(shí)時(shí)成像技術(shù)”的報(bào)告，屆時(shí)謝博士將介紹MEMS加工技術(shù)、MEMS微鏡和微透鏡等微型光學(xué)器件。這些微型光學(xué)器件使無(wú)損實(shí)時(shí)“光學(xué)切片”內(nèi)窺鏡三維影像成為可能，這是內(nèi)窺鏡技術(shù)的一次巨大變革。另外，還將特別介紹基于MEMS的光相干斷層掃描（OCT）,共聚焦和非線性光學(xué)內(nèi)窺鏡影像技術(shù)及其在早期癌癥診斷和腫瘤精準(zhǔn)切除手術(shù)方面的應(yīng)用。 
Abstract:

Over 7 million people die of cancer worldwide each year. The high mortality is mainly due to the lack of early cancer detection modalities especially for internal organs. CT, MRI and ultrasound imaging have issues of low resolution, low contrast, safety, or high cost. Several optical imaging techniques provide high-resolution cross-sectional information suitable for in vivo noninvasive early cancer diagnosis. However, these optical imaging systems are typically bulky and slow, and thus are difficult to apply to internal organs where most cancers are originated. Microelectromechanical systems (MEMS) technology offers the advantages of small size and fast scan speed, providing a tremendous opportunity for realizing real-time in vivo endoscopic imaging. In this talk, a unique MEMS technology that can create large-range, multi-axis, rapid scanning micromirrors and microlenses will be introduced. These MEMS devices in turn enable endoscopic optical “biopsy” modalities, resulting in a paradigm shift of optical imaging of internal organs. In particular, MEMS based 3D endoscopic optical coherence tomography (OCT) imaging, nonlinear optical imaging and confocal imaging will be introduced and in vivo experimental results of animals will be presented.
