Many respiratory motion compensation approaches in radiation therapy of thoracic and abdominal tumors are guided by external breathing signals. Patient-specific correspondence models based on planning 4D data are used to relate signal measurements to internal motion. The motion estimation accuracy of these models during a treatment fraction depends on the degree of inter-fraction motion variati...

In this work, we present an integrated approach for planning collision-free grasping motions. The proposed Grasp–RRT planner combines the three main tasks needed for grasping an object: building a feasible grasp, solving the inverse kinematics problem and searching a collision-free trajectory that brings the hand to the grasping pose. Therefore, RRT-based algorithms are used to build a tree of ...

PURPOSE To evaluate the effectiveness of impedance-controlled microcurrent therapy for managing treatment sequelae in head-and-neck cancer patients. METHODS AND MATERIALS Between January 1998 and June 1999, 26 patients who were experiencing late effects of radiotherapy were treated b.i.d. with impedance-controlled microcurrent therapy for 1 week. Objective range-of-motion measurements were ma...

Inter- and intra-fractional prostate motion can deteriorate the dose distribution in extremely hypofractionated intensity-modulated proton therapy. We used verification CTs data calculated from 1024 records to develop a voxel-wise based 4-dimensional method, which had time resolution of 1 second, assess impact motion. An example 100 fractional simulations revealed that minimal on planning dose,...

A dual-transducer system was used to test concepts for on-line guidance and lesion monitoring during ultrasound therapy. The system used a spherical-cap therapy transducer (4 MHz; 40-mm dia.; 90-mm focus) with a central, collinear transducer (7.5 MHz; 10-mm dia.) for A-mode examination. A digital system provided 3 operational modes, tested in in-vitro liver. Mode 1 senses in-situ therapy-beam h...

This study aims to find out how apply the dominant motion pattern based on video tutorials as a medium for physical therapy children with special needs. The research method used is survey questionnaire instrument. found that therapeutic at home needs in aged 6-11 years get less significant results do home. conclusion application of tutorial-based patterns an ineffective without particular compa...

Given the observed abnormal motion dynamics of patients with heart conditions, quantifying cardiac motion in both normal and pathological cases can provide useful insights for therapy planning. In order to be able to analyse the motion over multiple subjects in a robust manner, it is desirable to represent the motion by a low number of parameters. We propose a reduced order cardiac motion model...

This study aims to socialize an independent therapy program for parents of children with cerebral palsy. Self-therapy can be done at home using simple tools. In practice, this research conducts training through workshops and webinars. The webinars discussed the implementation self-therapy use maracas as a therapeutic tool. method used is qualitative descriptive approach. results were reviewed f...
