Abstract

Omnidirectional side-view images from miniaturized catadioptric endoscopes may be used to generate mosaics of the epithelium of tubular organs, enabling the longitudinal monitoring of surface pathologies. Here, previous results are extended to create three-dimensional sub-mm resolution 3.5 cm × 360° reconstructions of pediatric cardiac phantoms. From image stacks with a single annulus of best focus captured via parabolic mirrors, adjacent rings within the focused region may be used to infer depth via parallax while rings of best focus are used to color the inferred geometry. Potential applications include digital reconstruction of pediatric and small-animal organs for diagnostics and surgical guidance at near-cellular resolution.
