background: a method to track liver tumor motion signals from fluoroscopic images without any implanted gold fiducial markers was proposed in this study to overcome the adverse effects on precise tumor irradiation caused by respiratory movement. materials and methods: the method was based on the following idea: (i) before treatment, a series of fluoroscopic images corresponding to different bre...

We present a method to determine the 3D spatial locations of joints of a human body from a monocular video sequence of a Bharatanatyam dance. The proposed method uses domain specific knowledge to track major joints of the human in motion from the two dimensional input data. We then make use of various physical and motion constraints regarding the human body to construct a set of feasible 3D pos...

Background: The aim of this work was to study the feasibility of constructing a fast thorax model suitable for simulating lung motion due to respiration using only one CT dataset. Materials and Methods: For each of six patients with different thorax sizes, two sets of CT images were obtained in single-breath-hold inhale and exhale stages in the supine position. The CT images were then ...

This paper shows how to effectively compute collision-free and dynamically-feasible robot motion trajectories from an initial state to a goal region by combining sampling-based motion planning over the continuous state space with forward and backward discrete search over a workspace decomposition. Backward discrete search is used to estimate the cost of reaching the goal from each workspace reg...

The accessibility verification of the assembly/disassembly plays an important role in the process of product design. In the last decade, the sampling based motion planners have been successfully applied to solve the accessibility verification. However, the narrow passage which is a common problem in the assembly tasks is still a bottleneck. Meanwhile, the requirement of perception and emotion a...

in many infeasible linear programs it is important to construct it to a feasible problem with a minimum pa-rameters changing corresponding to a given nonnegative vector. this paper defines a new inverse problem, called “inverse feasible problem”. for a given infeasible polyhedron and an n-vector a minimum perturba-tion on the parameters can be applied and then a feasible polyhedron is concluded.

Virtual characters often have their motion defined by an animation database, as is typical in video games. We organize an animation database into a parametrized motion graph. Motion graphs structure animation databases: Nodes in the graph represent decision points, and edges represent feasible transitions between motions. Rose et al. [1998] and Heck and Gleicher [2007] extend this structure whe...

Introduction: In radiotherapy with external surrogates, exact information of tumor position is one of the key factors that improves treatment delivery. Many dynamic tumors in thorax region of patient move mainly due to respiration and are known as intra-fractional motion error that must be compensated, as well. One of clinical strategy is using Stereotactic Body Radiation Thera...
