Self-supervised Dense 3D Reconstruction from Monocular Endoscopic Video [PDF]
arXiv, 2019 We present a self-supervised learning-based pipeline for dense 3D reconstruction from full-length monocular endoscopic videos without a priori modeling of anatomy or shading. Our method only relies on unlabeled monocular endoscopic videos and conventional multi-view stereo algorithms, and requires neither manual interaction nor patient CT in both ...

The Agger Nasi Dacryocystorhinostomy: A New Technique for Endoscopic Dacryocystorhinostomy
European Journal of Rhinology and AllergyObjective: Endoscopic dacryocystorhinostomy (DCR) is the gold-standard procedure for the treatment of nasolacrimal duct obstruction, aiming to open the lacrimal sac (LS) directly into the nasal cavity and thus re-establish drainage of the tear pathways ...

Endoscopic character identities for metaplectic groups [PDF]
arXiv, 2018 In this paper, we prove the conjectural endoscopic character identities for tempered representations of metaplectic group $Mp_{2n}$ based on the formalism of endoscopy theory by J. Adams, D. Renard and W.W. Li.

Fourier holographic endoscopy for label-free imaging through a narrow and curved passage [PDF]
arXiv, 2020 Ultrathin lensless fibre endoscopes offer minimally invasive investigation, but they mostly operate as a rigid type due to the need for prior calibration of a fibre probe. Furthermore, most implementations work in fluorescence mode rather than label-free imaging mode, making them unsuitable for medicine and industry.

Powered Endoscopic Dacryocystorhinostomy: Raising the Bar
Delhi Journal of Ophthalmology, 2019 Purpose: This study was done to assess the efficacy of powered endoscopic dacryocystorhinostomy (DCR) with creation of a large bony ostium exposing fundus of the sac and primary mucosal anastomosis.

Automatic Tip Detection of Surgical Instruments in Biportal Endoscopic Spine Surgery [PDF]
arXiv, 2019 Some endoscopic surgeries require a surgeon to hold the endoscope with one hand and the surgical instruments with the other hand to perform the actual surgery with correct vision. Recent technical advances in deep learning as well as in robotics can introduce robotics to these endoscopic surgeries.
