TL;DR: The proposed approach effectively works with non-fluorescein fundus images and proves highly accurate and robust in complicated regions such as the central reflex, close vessels, and crossover points, despite a high level of illumination noise in the original data.

TL;DR: A model on topology change and deformation of soft tissue, referred to as the hybrid condensed finite element model, based on the volumetric finite element method, which has the ability to achieve an interactive frame rate for the topologychange in surgical simulation on standard PC platform.

TL;DR: An improved scheme of an interactive finite element model for simulating the surgical process of organ deformation, cutting, dragging, and poking, which can maximally compromise the flexibility and reality of soft-tissue models is proposed.

TL;DR: Effective range-computation and confidence-estimation methods are proposed to handle the problems of textureless regions, outliers and detail loss and these difficult problems are handled effectively by a robust model that outputs an accurate and dense reconstruction as the final result from an input of multiple images captured by a normal camera.

TL;DR: In this paper, the authors describe various techniques used in developing a virtual reality system for anatomic visualization and training arthroscopic knee surgeons and present various developments in segmentation, personal-computer-based realtime volume visualization, soft tissue deformation with topological change in real-time using finite element analysis, and soft tissue cutting with tactile feedback.
