Teletex is a new international telecommunication service that provides direct electronic document exchange between such office text machines as electronic typewriters and word processors that are equipped with transmitting and receiving storages. Teletex is an international standard aimed at integrating office products and worldwide telecommunication. It represents a major step in the developme...

In this paper we describe a test-bed we have developed for simulation of abdominal trauma surgery. The abdominal surgery scene is highly complex and contains many layers of deformable organs. Representing this layered and deformable anatomy with models that can interact, be probed and cut presents a unique challenge. We have met this challenge by applying a variety of technology advances in def...

Deformable models often require some degree of user-interaction to produce an accurate segmentation of the feature object. We propose an automatic deformable surface for segmenting the femur from magnetic resonance volumes of the knee. In order to overcome the limitations of many existing deformable models, probabilistic labelling is used to drive the deformation process, together with a surfac...

Contact involving soft materials often combines dry adhesion, sliding friction, and large deformations. At the local level, these three aspects are rarely captured simultaneously, but included in theoretical models by Mergel et al., (2019). We here develop a corresponding finite element framework that captures 3D finite-strain contact of two deformable bodies. This is suitable to investigate fr...

PURPOSE We evaluated the performance of organ contour propagation from a planning computed tomography to cone-beam computed tomography with deformable image registration by comparing contours to manual contouring. MATERIALS AND METHODS Sixteen patients were retrospectively identified based on showing considerable physical change throughout the course of treatment. Multiple organs in the 3 reg...

Deformable models provide a promising and vigorously researched model-based approach to computer-assisted medical image analysis. The widely recognized potency of deformable models stems from their ability to segment, match, and track images of anatomic structures by exploiting (bottom-up) constraints derived from the image data together with (top-down) a priori knowledge about the location, si...

This paper describes a new approach to the tracking of complex shapes through image sequences, that combines deformable region models and deformable contours. A new deformable region model is presented: its optimisation is based on texture correlation and is constrained by the use of a motion model, such as rigid, aane or homographic. The use of texture information (versus edge information) not...

This thesis presents novel algorithms for deformable dynamics, collision detection and contact resolution between reduced nonlinear 3D deformable objects, for use in interactive computer graphics and haptics. The deformable models investigated are elastic, volumetric, and capable of undergoing large deformations. Each mesh vertex of a general 3D deformable object has three degrees of freedom. N...
