A review of MEMS scanner based endoscopic optical imaging probe

Progress toward early diagnosis of cancer would have important clinical benefits in reducing cancer mortality; thus, there is an important need to image cellular features of cancer in vivo and in real-time. In this paper, we describe a review of microelectromechanical systems (MEMS) scanner based endoscopic optical coherence tomography (OCT), two-photon (2P), and confocal imaging. These modalities can provide submicron- and micro-scale resolution to reveal both cells and molecular features of early cancer diagnosis.
