Fernando Eleazar García Ramírez : "Integration and study of a MOEMS-based endomicroscopic system for early detection of gastrointestinal cancers by SS-OCT3

 Abstract: "In 2018, gastrointestinal (GI) cancers represented the 26.3 % of all the cases worldwide. Many imaging modalities are used for detection and diagnosis of GI cancers, but some are invasive, slow, expensive or they do not provide enough resolution and penetration depth for early detection. A promising imaging technique for GI cancers detection at initial stages is Optical Coherence Tomography (OCT) due to its non-invasiveness, high axial resolution and capacity to produce cross- sectional images. Furthermore, OCT is compatible with robotic endoscopic arms but requires the insertion of miniaturized probes through the endoscope. This demand has been addressed through Micro-Opto-Electro-Mechanical Systems (MOEMS) technology which enables batch fabrication of the key components of these probes. A 2-axis electrothermal micro scanner and a Mirau micro- interferometer were developed at the FEMTO-ST Institute for OCT endoscopic applications. The main objectives of this thesis are to fabricate the miniature endoscopic OCT probe by the integration of all the MOEMS components, to characterize its scanning performances and to develop the OCT experimental system for OCT signals acquisition, scanner control to perform Lissajous scanning and 2D and 3D image production."[...]
