Medical procedures often involve the use of the tactile sense to manipulate organs or tissues
by using special tools. Doctors require extensive preparation in order to perform them …

Detailed finite element modelling of needle insertions into soft tissue phantoms encounters
difficulties of large deformations, high friction, contact loading and material failure. This …

The modeling of breast deformations is of interest in medical applications such as image-
guided biopsy, or image registration for diagnostic purposes. In order to have such …

Purpose Surgical simulators need to simulate interactive cutting of deformable objects in
real time. The goal of this work was to design an interactive cutting algorithm that eliminates …

This paper presents a comprehensive study of the impact of visual-haptic spatial
discrepancies on human performance in a targeting task conducted in a visual-haptic virtual …

Medical palpation is a key skill for clinicians. It is typically trained using animal and synthetic
models, which however raise ethical concerns and produce high volumes of consumables …

This paper focuses on the use of virtual fixtures to improve the learning of basic skills for
laparoscopic surgery. Five virtual fixtures are defined, integrated into a virtual surgical …

Purpose–In this study, a new methodology to evaluate the performance of physics
simulation engines (PSEs) when used in haptic virtual assembly applications is proposed …

Simulators for virtual surgery training need to perform complex calculations very quickly to
provide realistic haptic and visual interactions with a user. The complexity is further …

Visual-haptic interactions are of utmost importance for VR surgical simulators. We
investigate the role of spatial visual-haptic discrepancy by manipulating the presentation …
