The motion track is an important feature to show the spatio-temporal relationship of a video object [2, 5, 7, 8]. In this paper, we propose a novel motion track representation to represent the motion track in the X-Y plane and the trend of velocity changes. Moreover, a new similarity measure for comparing two motion tracks based on the representation is proposed. Furthermore, the motion track s...

Strategies for delivering radiation to a moving lesion each require a margin to compensate for uncertainties in treatment. These motion margins have been determined here by separating the total uncertainty into components. Probability density functions for the individual sources of uncertainty were calculated for ten motion traces obtained from the literature. Motion margins required to compens...

Traditional approaches to the motion-planning problem can be classified into solutions for single-query and multiple-query problems with the tradeoffs on run-time computation cost and adaptability to environment changes. In this paper, we propose a novel approach to the problem that can learn incrementally on every planning query and effectively manage the learned road-map as the process goes o...

Scanned ion beam therapy has special demands for treatment of intra-fractionally moving tumors such as lesions in lung or liver. Interplay effects between beam and organ motion can in those settings lead to under-dosage of the target volume. Dedicated treatment techniques such as gating or abdominal compression are required. In addition 4D treatment planning should be used to determine strategi...

Session management of a telerobotic operation is an important aspect which has not been adequately addressed. This paper describes work performed by the Universities Space Automation/Robotics Consortium (USARC) which allows dynamic connguration and monitoring of a telerobotic system which is distributed over a wide-area network. The Telerobotic Session Manager (TSM) allows the session manager t...

Radiation therapy is subject to uncertainties that need to be accounted for when determining a suitable treatment plan for a cancer patient. For lung and liver tumors, the presence of breathing motion during treatment is a challenge to the effective and reliable delivery of the radiation. In this paper, we build a model of motion uncertainty using probability density functions that describe bre...

In radiation therapy, the estimation of torso deformations due to respiratory motion is an essential component for real-time tumor tracking solutions. Using range imaging (RI) sensors for continuous monitoring during the treatment, the 3-D surface motion field is reconstructed by a non-rigid registration of the patient’s instantaneous body surface to a reference. Typically, surface registration...

Electrowetting (EW)-induced droplet motion has been studied over the last decade in view of its promising applications in the field of microfluidics. The objective of the present work is to analyze the physics underlying two specific EW-based applications for microelectronics thermal management. The first of these involves heat absorption by liquid droplets moving on the surface of a chip under...

[Purpose] The purpose of this study was to investigate the effects of using a device for the self-measurement of cervical range of motion on neck pain experienced by a computer user. [Subject] A 39-year-old male subject with neck pain caused by working on a computer was selected for the study. [Methods] The instrument was developed for the study, and that the instrument is used to self-measure ...
