C3VD-DEFCOL: A Deformable Colonoscopy Dataset with Time-Resolved 3D Ground Truth and Realistic Appearance
Ethan Luk, Mayank V. Golhar, Anthony Song +5
3D reconstruction could improve colonoscopy by estimating mucosal coverage and alerting clinicians to missed regions during screening. However, algorithm development is limited as…
Virtual 3D H&E Staining from Phase-contrast Back-illumination Interference Tomography
Anthony Song, Boyan Zhou, Mayank Golhar +3
Three-dimensional (3D) histopathology of unprocessed tissues has the potential to transform disease management by enabling volumetric characterization of tissue microarchitecture a…
C3VDv2 -- Colonoscopy 3D video dataset with enhanced realism
Mayank V. Golhar, Lucas Sebastian Galeano Fretes, Loren Ayers +3
Spatial computer vision techniques have the potential to improve the diagnostic performance of colonoscopy. However, the lack of 3D colonoscopy datasets for training and validation…
Multi-contrast laser endoscopy for in vivo gastrointestinal imaging
Taylor L. Bobrow, Mayank Golhar, Suchapa Arayakarnkul +3
White light endoscopy is the clinical gold standard for detecting diseases in the gastrointestinal tract. Most applications involve identifying visual abnormalities in tissue color…
Speckle-illumination spatial frequency domain imaging with a stereo laparoscope for profile-corrected optical property mapping
Anthony A. Song, Mason T. Chen, Taylor L. Bobrow +1
We introduce a compact, two-camera laparoscope that combines active stereo depth estimation and speckle-illumination spatial frequency domain imaging (si-SFDI) to map profile-corre…
fundus imaging and computational refocusing with a diffuser-based fundus camera
Corey Simmerer, Marisa Morakis, Lei Tian +3
Significance: Access to diagnostic eye care could be expanded with high-throughput and easy-to-use tools. Phase mask-based imaging may improve the fundus camera by enabling computa…
