robotic virtual endoscopy development of a multidirectional Rigid Endoscope commetnaries
Neurosurgery, 2008Co-Authors: Michael J. Levy, Andy Nguyen, Henry E. Aryan, Rahul Jandial, Hal S. Meltzer, Michael L.j. Apuzzo, Felice Esposito, Paolo Cappabianca, Andre J Grotenhuis, Charles Y LiuAbstract:INTRODUCTION: The use of neuroendoscopy has increased in the past 20 years. Despite an increase in the number of indications for use, novel adjuncts and modifications to existing Endoscopes remain all but nonexistent. We introduce a robotic virtual Endoscope with applications for neurosurgery that could serve as a novel step in the evolution of future endoscopic technologies. METHODS: Over the past 8 years, we have worked on the construction of a prototype Endoscope with three degrees of freedom that was designed to allow for enhanced safety while maximizing the benefits of virtual field rendition and robotic control. We have developed a prototype to examine a cerebral ventricular model in vitro that functions via either a direct video- or computer-based interface. RESULTS: Assessment of viewing angulation with robotic feedback has verified the accuracy of the prototype. Models support the ability of the Endoscope to localize regions identified via a software interface. CONCLUSION: The Endoscope is a Rigid virtual robotic Endoscope that provides complete visual coverage of a three-dimensional space by controlling an adjustable viewing direction with three degrees of freedom.

video assisted endoscopic laryngosurgery using a direct laryngoscope and a long Rigid Endoscope
Diagnostic and Therapeutic Endoscopy, 2000Co-Authors: Masahiro Kawaida, Hiroyuki Fukuda, Naoyuki KohnoAbstract:Endolaryngeal microscopic laryngosurgery (microlaryngosurgery) using a direct laryngoscope is the preferred surgical method for treating laryngeal lesions under general anesthesia. However, this method does not provide a wide-angle view of the larynx and does not allow detailed observations of the ventricle and subglottis of the laryngeal cavity, resulting in blind areas. Video-assisted endoscopic laryngosurgery using a direct laryngoscope and a long transurethral Rigid Endoscope was therefore utilized to allow clear observations and complete resection of laryngeal lesions in these blind areas. This endoscopic surgical technique is introduced, and clinical cases are presented.

Polarized multispectral imaging in a Rigid Endoscope based on elastic light scattering spectroscopy
Biomedical Optics Express, 2012Co-Authors: Clement Barriere, Tobias C. Wood, Daniel S. ElsonAbstract:Elastic light scattering spectroscopy (LSS) is widely utilized to investigate cellular structures in cultured cells and various tissues. However, few imaging systems, especially endoscopic imaging systems, can implement LSS. It is the aim of this work to create a polarized multispectral imaging system based around a Rigid Endoscope to detect micrometer sized particles using LSS. The instrument first validated with different sized mono-disperse polystyrene microspheres, then an image is reconstructed based on LSS which shows the differentiation of different sized microspheres. Finally a preliminary experiment is conducted to demonstrate its capability to discriminate different types of cells.

2010 IEEE Photonics Society Winter Topicals Meeting Series (WTM), 2010Co-Authors: Tobias C. Wood, Kevin R. Koh, Daniel S. ElsonAbstract:A hyperspectral fluorescence and polarisation resolved imaging system incorporating a Rigid Endoscope has been developed for tissue characterisation. A full Mueller Matrix has been recorded for two commercial Endoscopes to allow for correction of the complex polarisation properties.
